Lidl Parkside 12V Power Tool Battery Stripdown - Very Revealing

[@billconiston8091]

The new 12v batteries in Lidl UK stores this week have "cell balancing - longer battery life. Increased lifespan" written on both the 2ah and the 4ah packs

[@patricksweetman3285]

Looking forward to you testing the individual cells, Julian.

[@marcellucassen8033]

I have a parkside cordless drill and a few years ago after little use one cell went out of balance to about 3.6 volt while the other cells (2) where both at about 4.2 volt When put on the charger it said it was full after a few seconds but then put in the drill it said it was empty! I took it apart and measured the voltages of each cell and charged one cell (the 3.6 volt one) with a li-ion single cell charger by connecting wires from the charger to that single cell and after putting it back together and using it for a few years now and many charge/discharge cycles I can say it seems to have worked, the drill works as it should and charging when it's empty is as normal a couple of hours till full

[@lint2023]

Marcel - I've done the same "manual balancing" on a Hitachi battery pack and also have been using them for years afterwards. It pays to think! Cheers.

[@TomsManShed]

Great vid with interesting info I can vouch for how good Lidl's customer service is....I had a small 12v 2 amp (the single stick pack) drill/driver that after 2 years 10 months of heavyish use started splitting at the back....the 2 halves were coming apart ...tightening the screws didnt help so must be stripped threads in the plastic...it worked but was stuck in 1 speed as switch wouldnt move. I rang them up (keep receipt) and they sent me a new one inc case and battery and said keep old one :) yep nearly 3 years old! (still using it)......great service Have done quite a few reviews of their tools on my channel.

[@mickeyfilmer5551]

They were still at full price in my local Lidl, but the manager said they may go down on Thursday.

[@MrOrangeman18]

Just bought one to open up and use for the cells. And it looks to me like they Are balanced. Each cell is monitored by the board and thus possibly balance as well? Also. Has anyone found a data sheet on these cells?

[@lumsdot]

Today Lidl are selling 20v 2ah drill batteries for 11.99 which is a good buy. Plus on thingyverse you can find 3d designs that allow you to convert them to other battery types. ive done one that converts it to work with an einhell drill, you just need to cut up a tin to make two contacts which are pushed into the 3d print at the end

[@dodgydruid]

I bought Parkside's cordless drill a few years back and its been superb, am surprised the batteries haven't gone yet either as its had a fair few down to the red indicator then charged and over the years and it holds the charge for ages with little dribble of max potential. I have the 20v pack for my Parkside impact driver and that too can be left for months and still be fully charged. I don't know what they use in the Parkside dremel kit but had one of them for coming up two years and apart from a bit noisy at full steam again holds charge without loss in between uses but I haven't seen the dremel tool battery's come up in Lidl's as I would buy another. Parkside is quite unusual in that most of its stuff is still made in Germany rather than some oblique factory in Shenzuen which is becoming a rarity in electrical tools.

[@wintersliam9558]

Over the last couple of years there have been various 12V tools on offer from Lidl. However while the general form factor of the battery has stayed the same, there have been minor subtle changes in the battery shape and in the tool battery receptacle areas. The outcome of this is that batteries which are the same approximate form factor and the same voltage are not interchangeable. Likely a deliberate ploy on Lidl’s part.

[@mattylad8035]

To make them interchangeable, simply remove the plastic splines on the side with a sharp knife - then they should fit.

[@michal6690]

Balncing is not problem when You use device to heavy job's. Please notice that the much of expensive device like Makita also don't have balncing system. However when You check each cells after year using, You can see that each cells have the same voltage to 0.001 volt.is isvery interesting phenomen

[@samdeur]

only person i have heard talking about the balancing of the cells.. thanks for that..

[@foxabilo]

Julian, I believe the method that is used is to short all the +'s together and all the -'s together so any cell that tried to undervolt is pulled up by virtue of being connected to the other cells. I know when I first saw this method I was somewhat stumped and even wrote to some manufactures about it, but it seems to be an accepted industry standard now not to balance cells as used to be done, but as I said to crowbar clamp the cells to one another. But when the cells are in series I am still very concerned that an overvolt situation could arise and cause a fire by overcharging.

[@JulianIlett]

It's hugely complicated to switch (electronically) cells from a series string to a parallel array. I thought about this method of balancing but gave up trying to design the switching matrix. That's why I like the inverter balancing technique :)

[@foxabilo]

@@JulianIlett I guess there is a possibility that the newer cell chemistry has a form of negative feedback built in, so that as the cell approaches a fully charged state its internal resistance decreases allowing more of the current to flow into the other cells, be worth an experiment to see.

[@superdau]

@@foxabilo No that's not possible. There is no magic ingredient that makes other cells take more current when one of the cells is getting full. If cells are in series they always get (or deliver) the same current. That is just physics. If they are in parallel they will always be at the same voltage (physics again). That is the whole reason for having external battery protection boards (and balanced charging circuits in some cases) in the first place.

[@foxabilo]

ohh also try a UV light on the cell cases for hidden lettering

4 years ago I bought two 22400mAh powerbanks (8 cells) for £12.99 each on Amazon. I should have bought more since the price per cell was so low that its hard to find them at that price even these days.

[@NOWThatsRichy]

Interesting vid, as I've just bought one of those Parkside drill/drivers, (I've just done a review of it on my channel), seems to be well made & ideal for smaller jobs, instead of getting out the mains powered drill. I've just dismantled an old summerhouse in the garden, using the screwdriver function , the battery is still showing full charge! I was tempted to have a look inside the battery pack, you've saved me the trouble of doing that! I'm surprised at the amount of charge control circuitry in the actual battery pack, I thought most of it would have been in the charger itself. I've bought several of Lidl's mains power tools over the last few years & not had any real problems with them, The 'florabest' lawnmower is on its fifth season & still going strong!

A lot of laptop battery packs are also not balanced. That is the most common design. There should be a law against that.

[@rich1051414]

They want the batteries to kill themselves after a while. Since they are in series, when a cell dies, it usually doesn't cause a fire, so they are ok with it.

[@californiakayaker]

I've bought about 20 or more brands of oem and replacement laptop batteries, have about 200 cells all new, , and a collection of various BMS arrangements which came in them. So far every one of them, all brands types of lithium 18650 laptop batteries had BMS circuit boards with balancing.

[@ChipGuy]

@@californiakayaker Interesting. Than that must have changed within the past few years. When I had loads of dead battery packs from various laptops (like 30 of them) I opened them all out of curiousity and found not one balancing circuit. Only voltage measurement and when the first battery hits max. voltage -> cutoff.

[@californiakayaker]

@@ChipGuyWell, I've got a box of BMS circuits from laptop batteries. Each one has a set of discharge resistors. One thing that is different about them is they require control from the laptop to work.

[@superdau]

@@ChipGuy Out of the 10-15 laptop battery packs I opened I have also yet to see a one with balancing. They sure weren't the newest (luckily they don't break THAT fast), but something between 5-15 years old (not at the time of opening, but relative to now; or let's say from 2005-2015). I've seen newer laptops using pouch cells now (because cramming in everything even tighter to keep the heat in is better, right?). Never took one of those laptops that far apart though that I checked for balancing circuits.

[@lezbriddon]

the cells stay balanced, or at least they do on the 20v packs. I think some of these cheaper ones go for midpoint balancing... stopping charge as soon as any battery hits 4.2 and stopping discharge as soon as any hits 2.8, this way capacity is slightly reduced but keeps evryone safe. would be interesting @julian if you knock a cell out of balance to see if the pack recovers on these ''simpler'' packs, that said, they look a lot better designed than the ferrex packs from aldi.

Cell balancing is overrated. Yes, it works but I don't think is worth the time and energy wasted for it, especially in power tool battery packs that see a lot of quick charge/discharge cycles.

[@melkiorwiseman5234]

It's definitely needed for lithium techology, because the chemistry in the batteries won't be identical and one will always discharge a bit before the others and conversely not take as much charge as the others. You'll always end up having to either overcharge the other two cells in order to get the lowest cell back to capacity, which risks the overcharged cells bursting into flame, or over-discharging the bad cell and damaging its chemistry which will exacerbate the problem, unless you periodically perform a manual charge of each individual cell (or cell block) to get them into a balanced state. It's safer and less trouble to just use a cheap balancing circuit.

[@caskwith]

I don't think any of these cheaper Li-ion batteries do any kind of balancing. I have some Draper batteries, identical to an Aldi tool system. I have had two packs die now (all draper, none of the aldi interestingly), when I took them apart it was clear that is a simple series circuit with some overvoltage/overheat protection but that's all. In both packs it was one cell that was faulty, then likely overcharged by the other cells and then failed.

[@grahamrdyer6322]

I thought they where balanced, if it checks the cells over voltage parameters (each pair of cells) and the under voltage bit, surely that is balancing ?

[@Pistoletjes]

It depends on the action: if one cell's charged or overcharged and it cuts the charge current, the other cells will not be fully charged, effectively reducing the capacity of the set. If it only cuts the charge to the full cell and remains charging the rest, there's no problem.

[@YodaWhat]

@@Pistoletjes There i also _top balancing, middle balancing, and bottom balancing,_ which each have their own advantages and disadvantages.

[@ranvedsticon2304]

What would be a way to make this charge in a charger from another brand that has 3 pins(t,+,-)

[@PredragMrvic]

Just noticed: on the battery it says PAPK 12V A1 Which means they are old type non-balancing. Although the package says PAPK 12V B1 which ARE balanced type! This is probably why they give them away on such action price. Manufacturing error.

It also doesn’t make sense as the high capacity battery has it but the low capacity battery doesn’t. Further, there’s no connection for the ID pin in the charger, so that could cause issues if you plug a 12v battery into a 20v charger or vice versa

Within the first 40 seconds he says “this is a 12v 2Ah pack, and this one is a 12v 4Ah pack, and this one (the 4Ah battery) has a little button on top that the other one (the 2Ah battery) doesn’t have” Later when he opens it up, the larger capacity battery has 2 paralleled banks of 3x 3.6v batteries in series, giving double the capacity but the same voltage as the smaller capacity battery which just has 3 cells in series. He also flips the battery package over at around the 1 minute mark and it clearly says on the back 12v 4Ah for the larger battery

[@Mandrag0ras]

Julian, if you want cheap cells, you can just buy cheap cells. No need to look for special offers, discounts, surprise boxes, waste time and effort to disassemble, get cells with spikes after removing spot welded tabs, cut yourself, void warranty and gets stuck with overdischarged cells or cells of unknown characteristics. It's too much trouble for nothing unless you do it out of surprise addiction. 1.75 pounds is 1.95 euro. As an example, look for Sanyo UR1865ZL2 2310mAh - 10A at eu dot nkon dot nl. It's 1.99 euro.

Question is - ARE YOU ACTUALLY GETTING the capacity written on the cells? The chenglish translation for 5mAh can be anything up to 3.6Ah. I remember well the sand filled cells from a few years ago. You could do with running a couple up and down a couple of times to see what reality says - ink is cheap at Aldi!

@@YodaWhat Yup - that's Big Clive who's 6'5" and tests batteries to destruction. To be fair to Julian, I like his reviews, but when it comes to batteries and especially LiLon/Lipo the only reason for using them is higher capacity - so its pretty fundamental knowing the real numbers. The point of a review is someone you trust making the investment of time and money on test equipment, then to get the kit and do the legwork and testing for you. It's not that hard - but not everyone has it all to hand. Given their tendency to meltdown - protection is quite important too. Branding (esp of chinesium) is mostly only a printer's whim and doesn't matter. It's the numbers that speak for themselves. BC's reliable numbers are one of the reasons for going back, he occasionally discovers quite splendid deals.

Which seems very unsafe to me, since it's far safer to have the balancing circuit in the battery pack than in the charger. Still, it's possibly cheaper, and it will work so long as you always use the correct charger, or at least a charger which includes a balance charge circuit.

Balancing adds a lot of complexity.

I get my 18650 batts $8 for a set of 8...brand new Samsung for a buck a piece :)

[@ewenwilby6495]

Hey Julian, Great video, very informative. If you decide to use the cells for a different project, would you consider donating the plastics from the 4Ah battery to me as i dropped my drill with one of those in and the casing has cracked on the top part and the triangular part.

[@Dirt-Diggler]

I use the larger 24V Lidl packs on many older NiCad power tools, cost nowt and it's ni on allways the NiCads that go way before the tool :)

[@Dirt-Diggler]

@Schwalbe262 still sold in Lidl UK stores, they are on Amazon BUT they are £21 !! In store normally £14.99, on sale £7.50 for the 2Ah battery 👍

[@Dirt-Diggler]

@Schwalbe262 just checked on eBay, they are £16.99 ish, PAP20A1 for the 2Ah 👍

These cells are really good and cheap. I stripped the 18volt batteries when they were reduced took the cell holders with cells out trimmed off any excess plastic and stacked them 5 layers high connected them in parallel and put that back in the case with threaded rods instead of the original screws to make to 2 18 volt 10 amp wrapped them in heat shrink. Connected these to batteries in series for my 36 volt electric bike conversion. They work fantastic.

[@fredjoyce4914]

Does anyone know if they work with Milwaukee m12

[@bobbobbins8913]

I bought a couple of the larger packs but without the riser - they only have five cells per pack. No matter...I just wanted some reasonable cells with spot welded tabs so that I could try rebuilding a couple of Hitachi 10.8V packs (only 1500mah). Worked a treat! The Hitachi packs are thoughtfully designed - unsolder a few wires and the three cells can be removed without having to hack into the frame (unlike the Parkside packs). Very pleased with the results - so thanks for the heads up!

[@jamest.5001]

I got a couple dozen LG cells, 6 for $10 or less that way, only 1.5ah, but can do 40amps, about 24 cells. Not so bad for new cells, I guess I'm going to replace nickel cells in my dewalt drill, I wonder if it will handle 6s cells? 24v being 18v components??

[@Andy-df5fj]

Let me guess..Kobalt battery? Most likely the motor can handle the extra 33% voltage fine, the main concern is the speed control.

[@springwoodcottage4248]

Fascinating the economics of 18650 cells. You are buying assembled units for less per cell than I can usually find the individual batteries. How can prices move in such strange ways? The cheapest I have found are the low capacity £1 units from Poundland, but otherwise they are usually over £2 each even if bought at 6 cells at the same time with the every concerning knowledge that what one is being sold might be a low capacity counterfeit. Has buying batteries ever been so Weird? Thanks for sharing!

[@fersunk]

It's the magic of bulk ordering the cells. The manufacturer can buy a no name cell and put their own sleeve for almost nothing, and the simplier and jellybean the components they use on the pack the cheaper it gets. And of course the more you produce the cheaper it gets because the tooling costs and manufacturing optimizations. The brand name cells they sell on specialized websites is grossly overpriced because just 1 cell price, shipping costs, and the biggest increment in price is the "fee" specialized website

[@YTANDY100]

i have an almost identical (pcb is different) battery (small) but is 10.8 volt 3 cell , it does charge to over 12 volt but the charger , battery and tool all day 10.8 volt :-) interesting to know it has no balancing , mine is in bits atm because it runs out quick so something new to check :-)

[@zaprodk]

Sounds like yours is LiFePo4 chemistry, which is pretty well charged at 3,6V per cell.

[@YTANDY100]

@@zaprodk ok , thank you :-)

[@superdau]

They are the same thing. 10.8V is the honest nominal voltage used by many manufacturers (honest, because most of the energy in a cell is around the nominal voltage and not the peak voltage). A cheap manufacturer will mark it as a "12V" battery, because that looks better on the label. Essentially the cells will be charged to 4.2V (so 12.6V for a 3S pack) in almost all types of li-ion batteries. Except for LiFePo4, which are li-ion batteries as well, but have a lower voltage. I doubt you have LiFePo4. They are more durable than other types, but their power and energy density is lower. So you see them mostly in things like e-bike, but almost never in anything like tools, powerbanks and other electronic devices.

Does this bms board can use for juts 3 cell

[@pollywollydo]

Have you looked at MR Dyson's offering ? Built like a tank

[@jakp8777]

Quite odd that the printing on the cells is over the tape.

[@josslevy4240]

Transparent tape?

[@zaprodk]

It's not. The tape is very translucent when there is only one layer of it.

[@jakp8777]

joss levy sure doesn’t look transparent with the yellow color typical of transformer tape. If the tape was transparent or opaque it would be blue or blue under the tape.

[@zaprodk]

@@jakp8777 Look at the video at 03:56. It's clear on the bottom cell that it gets blurry where there is two layers of tape. I've taken a lot of battery packs apart and replaced cells. The cells are printed in the factory with an inkjet head and it would not be practically feasible to put the assembled pack in some sorts of weird shaped jig, move it a lot of times and put it trough the machine to do the printing, so clearly the printing came before the text. My experience is also that if the tape has been sitting there for a long time, some of the ink leaches into it, and will come off if you take off the tape.

A ‘googlewhack’ as popularised by Dave Gorman usually means a term which gives a unique (and correct) result when given to google search ... rather than nil results.

I should've said 'Google lack' :)

You have extreme low prices in UK. we also had these packs in our LIDL stores (Denmark) the 2Ah with also Grizzly cells cost 99 DKK (12 GBP) and the 4Ah also with Grizzly cells was 179 DKK (22GBP) i.imgur.com/z95v8Wz.png so shockingly fare from the MSRP before sale price. and batteries will never come on sale here... just as many of these LIDL tools are not carried here. The only two was the 12vdrill and the 12v multitool for these batteries a few weeks back there both costed 349DKK (42 GBP.) These tools cost 29Euro in Germany and 25GBP in the UK as I recall. Not sure what the reason is why the LIDL Germany (aka Schwarz group) set the prices here so much higher than all our neighboring countries..as they are the only one..even though they are not little here with a triple-digit number of stores. Aldi has the same prices in Denmark as our neighboring countries, so seem weird that LIDL inflate them as much, but the biggest problem is the very little selection of these tools, so if you buy a product with battery and charger, you are often not gonna get the chance for the other power tools that battery lineup also would work in. LIDL Denmark got a very low score amongst the public... bad leadership.

[@JAKOB1977]

Also recall LIDL got a lot of critics here amongst the media after young immigrant gangs terrorized one of their stores and often walk in and almost tried to empty the store for valued products and LIDL didn't dare to stand up for common sense but again and again let it happens and then trying to pay these young immigrant gangs by hiring them on make-believe jobs, like we where some kind of Wild West' where you pay your way out and doing that in such a situation will just unfold even more and make that criminal-offense even more lucrative for others. (lol maybe that is why the prices are higher, the Danes are simply paying for LIDL Denmark's lack of backbone.) Look int he 12v unit i got for these batteries and there is no centerpin for that 4A pack mid-center round pin. so definately not for the 12v angle grinder (B1 version) i.imgur.com/p934bKz.mp4 (brushless??)

[@martincounsell8061]

Thanks julian I have just contributed to global warming, all due to a wasted trip to Lidl at no reduction prices in Cheltenham and no larger packs in stock. Lidl say the price marked is what you pay, they say they don't have any other store tel numbers so I could check elsewhere. USELESS not you but Lidl. Keep up the cell hunting as they need to be about 75p- £1.00 range for 2000ma then things would change big time everyone wants them . Years ago I stupidly thought you could by a 7000mAh 18650 HA HA and now some are selling 9000mAh that's a bomb. Thanks for the hard work!

[@jamest.5001]

They probably do that so most will need to buy new battery packs, when one cell gets low and shuts the pack down!
