@Mickytdi it's a discontinued model that was based on the DHC BTW300. for the £35 i paid it was a bargain lol

@Mickytdi usually a shorted cell will heat up the battery while it self discharges and drop the volts to 9v give or take, its most likely each cell has dropped a small amount of voltage but can still show a good amp reading, ideally I'd like to get a good carbon pile battery load tester to compare to the conductence Testers as those actually put the battery under load and show up faults these Testers can miss or get wrong

@@azerotha4531Interestingly a friend has a 2023 Tiguan diesel. Has a 700 A battery EFB+. Voltage can be quite low. I often see it at 12.4 volts. Tester says it has its full 700 A EN. Starts fine but i have seen errors flashing up for a second when started up from cold. The car doesn’t get a lot of use so he periodically hooks it up to a charger every so often. I disconnected the sensor on his battery to disable the energy recouperation and start stop. However the battery still struggles to maintain a voltage over 12.4. I think an EFB should be 12.7 fully charged? As comparison my 2024 Octavia vRS diesel has the same battery and according to my BT battery monitor it’s resting at 12.69v

@Mickytdi does your battery tester have a start testing function to monitor what the voltage drops too, when Cranking? If the voltage drops too low it can cause errors in the ecu's which will throw up errors, with the battery connected to the car during testing untill all the systems have shut down there will be power consumption causing the voltage to be lower, best way to test a battery is remove the battery, fully charge then leave to rest 24 hours if after 24 hours the voltage drops back to 12.4v then ideally new battery but if it starts and he's happy to continue then just carry on it won't cause too many problems untill the day it dies lol, I have a T6.1 van and have the battery sensor permanently disconnected been like that 2 years lol

@ yeah it does. I didn’t bother testing cranking voltage because the errors told me it must be low lol. I checked voltage when everything shut down on the tiguan after an hour. Regarding testing cranking voltage i wonder is it that reliable on modern cars? My 2024 (8 months old) car with good resting voltage and tests over it’s 700a EN still gave a low cranking voltage this morning (8.5v according to BM) . Starter sounded brisk and started instantly.

@Mickytdi 8.5v is fine from memory anything bellow 7v on a fully charged battery is too low and each manufacturer will be different toyota hybrids can freak out when they drop bellow 12v, again there are just so many variables when it comes to batteries and each car manufacturer will behave differently. Most modern stop start smart charge cars will only keep the battery at around 12.4v this is to allow the battery to accept plenty of charge when using regenerative breaking, also vw batteries tend to show a lower test rating on the battery than they are actually rated for, the 700 amp efb varta made one is actually a 760amp but they lower the sticker rating to help it pass tests better. It lowers warranty claims lol, the 680 agm is actually a 760 agm with a lower rated sticker, vw audi group are tight on battery warranty claims. There is no hard evidence of this but if you look at the varta brand equivalent you will see a higher rating on those batteries compared to the varter made vag batteries 🤣

I know, hence, I tested some used batteries as well. You can test new batteries perfectly fine with the conductance testers but the batteries won't be at perfect health untill after several start cycles but they should still pass a test, if they fail then its pointless fitting it to the car as it will soon come back with a battery fault. This is also one reason hybrid and EV cars go through 12v batteries faster than standard internal combustion engines the current draw when turning them on isn't helping the plates stay in good condition, or condition them in the first place.

@ i found the cheaper Topdon arti 100 a very reliable indicator of my AGM battery failing over time. It was rated at 680 A EN. I watched it gradually drop to 350 A over the years. I could predict it failing with that tool. It started struggling to start at 350 when cold. The new battery i fitted was 760 A en but only read 560 A when new. After a couple months of use it read 790 A

@Mickytdi I've never actually seen a new battery test 200 Amps bellow the rating obviously not impossible lol most of the new batteries I test tend to be the rated number, higher or around 10% bellow the rated number, but your experience shows how much they can improve over time 👍

@ i have noticed temperature can give different results with these testers. I did come across one 5 year old battery that fooled my tester. A friend had a bad battery. My tester read 40 A over it’s rated A and passed it but was still causing intermittent low cranking issues. Do you see much of a Amperage loss before cranking issues? When someone comes to you with battery issues what’s the average SOH % are they reading? I replaced my last battery at 30% SOH. It still was starting but low cranking in frost.

@Mickytdi batteries are a mine field lol I've seen batteries show 800 amps out of 850 but when Cranking the voltage will drop to 2v the fault in the battery can sometimes trick the tester, these Testers are not perfect but they have a good track record, I did a range rover last week because the electronic boot would not lift open but when running it worked fine, the battery passed a test but was only just a pass, new battery on it and the boot was back to normal operation, modern cars have smart charge and stop start and most car manufacturers will have a 60 to 75% SOH replacement figures again this varies between manufacturers, older cars let's say pre 2000 can get away with 45 to 50% SOH before replacement is recommended. If I come across a car that fails a test but only just and once running the battery is accepting 50% or more of the AH then its a good chance a good charge will recover it but if the battery is say accepting less than 30% of its AH it will usually not recover you might get the odd one but most won't tricke chargers can do wonders to recover batteriesbut you will only know once you try to charge it. Temp plays a big part as the temp drops the engine reqs more amps to turn over but the batteries ability to deliver tge Amps drop, so if you have a car that needs say 300 amps to start the car at 20 degrees and the battery has 330 amps it will start fine once you hit say 0 degrees the engine will need say 320 amps but the battery can now only deliver 310 amps it might just catch and start or just not quite make it this is one reason batteries produce more power than needed to allow wear overtime and still be reliable and to deal with the very cold temps some places get, those numbers are just examples lol and not scientifically tested 🤣

@CJ.A-C surprisingly, you don't get instructions, and every video i watched never mentioned it lol, this is why comments help, every day is a school day, and the video wasn't how Accurate is the slider, its how well it tests batteries of certain designs and ages, on a regular basis I get people coming to me saying a various garages that failed a battery using various Testers when I tested it, using my works tester it passed, so I just wanted to try a few and see for my self, not all Testers are the same.

@@azerotha4531 well done .question what was your view on the launch.i use the 7 version overpriced over rated and expensive to run.i know only do a/c on trucks and cars . iknow 7 people who have the launch and not one of them have upgraded after 2 years up

@CJ.A-C it works great for my needs I'm in the breakdown industry and mainly use it for battery coding the dreaded adblue resets and general code reading and clearing, it will struggle to do the resets and coding on cars from 2022 onwards because most manufacturers are using secure diagnostic access which means you need to have accounts with them and pay them to unlock the control units to do the necessary resets coding etc, I also use the companies Bosch diagnostics which can unlock the moduels but it's a fiddley system to use and surprisingly the launch is simpler to use and actually does a better job, but when I need a car unlocked from the manufacturer I'll use the bosch to unlock the moduels which usually gives you an hour or 2 access, then use the launch to do the work, I paid about £700 for that unit with 2 year updates, the unit will continue to work fine once the updates run out but once you need it for a car that has been made after the last update it won't work effectively or at all, but if you tend to work on older cars there shouldn't be any issues. At the moment, it won't work on the brand new transit custom as launch have not yet done the software for it. Hopefully, they release that soon and if I didn't have the free updates I'd have to use bosch which I don't like lol.

@spannerman2887 I was going to get a carbon pile load tester, but I ran out of money child no2 due in 8 weeks, so spending has stopped for a while, well on battery equipment that is lol. I did do another video testing some 202 batteries from toyota lexus and VW and put them on a simple load that simulates a basic drain like lights left on etc, but for now that's about all I can do unless santa sends me one but I don't think he carries carbon pile load Testers 🤣

@ysjmichael can't say i remember seeing LOV before... was the battery still connected to the car? And do you get the same reading on every test?

@@azerotha4531 Yes the battery was still connected. I tested the charged battery after watching your video, so I was quite surprised to see anything other than number. I tested it twice, with same reading of 'LOV' - almost felt like a prank. Ring's website isn't particularly helpful. I had no problem starting the car, and checked the voltage on my return from a shop visit, still topped. I'll test it again soon to find out.

@ysjmichael try testing it with the battery disconnected from the car it's possible the electronics on the car are causing this weirdness this also happens with some battery Testers they put up an error untill the battery is disconnected from the car

@@azerotha4531 Potentially the electronics are causing this. I'll keep an eye on this and try testing again when it's not so windy.

@MrAsadEp it sure is, probably made by the same manufacturer lol, only difference is software and longer leads and button placement

@azerotha4531 glad I found your video re: yuasa unit. Saved me some money. How are you finding this unit?

@MrAsadEp it's all good probably not as good as the new midtronics but they are stupidly expensive, for the price this is good and that this can do lithium is a bonus, you do go through printer paper rather quickly lol, unless you just scan the QR code on the screen like I do saves on paper lol

@azerotha4531 Nice one, to be fair, this one isn't cheap cheap at around £300. Appreciate the comparisons.

@daveforster6617 it is strange. I'm personally a big fan of lexus I've had a few over the years, and out of all the cars I've had, they are still the cars I miss the most, hopefully they will get a grip on things and get it sorted

@daveforster6617 that will definitely help you. You just need to be careful with these cars, sitting in them without the ready light on listening to the radio is the main culprit and so is cleaning the inside without the ready light on. The LBX battery is actually less powerful than the yaris battery, which is just weird, I did a comparison video here kzbin.info/www/bejne/hWe3c6Csl9aGkNUsi=p1pHGABrtwmEa4uz

@carpman6495 Sweet, knowledge goes a long way 👍

@Devil_Z786 mine did the same after 6 or 7 months. Fortunately, I registered mine with ring and they sent me a new one.

@wags-waggy cheers, there are lot of people suffering with this issue both LBX and Yaris, the main reason for these videos is to help owners understand some of the problem, especially when dealers fob them off as there's no issue, or blame the owners for the battery going flat, LBX owners who don't know how to use the emergency door open leaver or that it's there, often get locked in the car, recently had one owner call 999 because he couldn't get out of the car.

@@azerotha4531 My LBX should arrive in the next couple of weeks but I've already bought a lithium jump pack in preparation. I've also got the Sealey BT3000 but that's mainly for my campervan which sits on the drive for weeks on end. Thanks for the informative videos!

I forgot to include; when the 12 volt battery goes flat in an EV you are absolutely 'dead in the water', hence the AA callouts. But why should I have to buy a booster? Should Toyota include one with the sale?

@jonnyboi6342 correct on a few things, a warranty claim from most manufacturers is only accepted on bad cell test results caused by manufacturing defects. Anything else is classed as ware and tear, imagine buying 2 new tyres then doing a burn out till they exploded or lost all tread the manufacturer won't cover that as its your fault lol, when im dealing with battery issues there are various things that need to be taken into consideration such as amount of use, milage, vehicle condition such as electrical faults amongst other things, a battery that fails a test or in this case won't hold good voltage is down to ware and tear and not warranty accepted and is fully explained to the owner, With regards the toyota batteries it's more of a quality issue they are the smart price of the battery world. A better quality battery will give better performance and last longer, the older AGM batteries they used lasted years, some 10+ years. With regards the charger I've got 3 of them all different ones, remember if the plates are worn out or damaged they won't recover, yes there are people that claim to be able to fully recover damaged batteries by doing all sorts but they either take a lot of faffing to do or it don't work, end of the day we live in the real world and people just don't want the hassle, new battery and away they go, most that have upgraded the quality of the battery get less issues, no car and no battery is immune to going flat or failing early on unless they are looked after, and everyone I go out to that has a flat battery regardless if the battery is good or bad gets the same advice on how to look after a battery and they all get the options to charge it up and see how they get on buy one from the company i work for or go elsewhere for new batteries, everyone has a choice that's theirs to make. Most yaris owners tend to buy a new battery because they have been the dealers a few times and gave got fed up with going there not having the car for upto a few days to be told stupid things like you need to do 12k per year and getting fobbed off. A good quality battery is always the best option and take things from there.

Yes, 21s century engineering and yet motor manufacturers produce cars like this that aren't fit for purpose. Apparently various Toyota owner's clubs suggest turning off all sorts of mod cons on their cars to minimise this 12v drain. Absolute nonsense. And of course you must not leave the car undriven for a few days.

@zbigniewrichard8291 Most modern cars do monitor the state of charge and state of health them self's. You can use diagnostic computers to see it in live data. Like yourself, I believe that info should be accessible on the dash. Some cars will give you battery voltage and charge voltage, but don't give you a state of health which is the most important, if your car gave you that info or popped up a warning saying battery heath bellow minimum requirement please replace, it would prevent a lot of flat battery breakdowns lol

@@azerotha4531 That is exactly what I want to avoid since most modern cars (including my car) don't even alert you about the battery's state of health. You just find that bad news at the worst possibly moment. I am particulary annoyed about missing SOC value on the dashboard since the electrical system of my car has a Battery Monitoring System device near the negative pole of the battery. That is why I presumed BST360 can send continuous data to my compatible Launch X431 Pro5 tablet that will draw a graph under Battery Test section.

@stephenkellett7382 still going strong. I've put a larger capacity panasonic 18650 in it as the keepower isn't the best out there, lol

@Milsmek it was still under VW warranty, so I just gave it to them to fix for free lol

@charliegeorge. cranking amps are not needed on a hybrid as the battery doesn't start the engine, the hybrid battery starts the engine. However, there is usually a corelation with CCA and AH. The higher the CCA, the higher the AH. One of the main issues with these batteries is quality, it's just not great. Any decent quality battery will be an upgrade even if it's the same 35AH, but as they say bigger is better lol, and 45AH is probably the biggest you can get in a battery of that size, as you can't fit a physically larger battery in the space.

@simplywinning1170 I think the mk3 is the same as the mk3.5 and has a lift pump that automatically primes the filter, but if you're not sure? Then, just top up the filter with diesel before putting the top back on. It should be OK. Mk2 and mk1 probably don't have lift pumps and would need priming

This would be a huge help! Pretty please!

@theLavaLounge_a9e The only reason is curiosity, just to see the physical design difference, I've seen people think that the mann filter is wrong because its totally different to the ford oe filter and the bosch, both ford and bosch are the same design and to see if the mann filter affects the remap i have on it, which it doesn't, and I'll compare the 2 filters after 5000 miles, I still have the last bosch filter sealed up so I can compare how they look after 5k miles, the main point of the video is to show how to change the filter and that the new filter doesn't need to look exactly like the old one on design.

@davidjames7325 not yet. However, there was a comment yesterday saying they have changed the design and removed the white pivot arm. I'm surprised that it being a common issue no one on the vw channels have done a video. Maybe comment on some vw repair channels and ask if they want to do a video of it.

@morganmuffel2678 the 2019 yaris should have the AGM type battery in the batteries on those tend to be very hardy. But again, they are a very small battery and very short infrequent journeys will cause this issue. Pre 2020 yaris are no where near as bad as these new ones, if it does have the older AGM battery I think those can be upgraded do a bigger battery it just needs the clamp modifying with hacksaw or grinder. The dealer won't do this, but a good independent could. Most hybrids from other manufacturers suffer this issue with short infrequent drives

Hi, thanks. How did you find out about this? Have you spoken to a VW garage? Thanks

@Dara-jz9hl yaris pre 2020 had agm batteries and had very few issues compared to the ones from 2020 onwards. However, the new ones do seem to be getting better with the latest software but the batteries are still low power compared to other makes of battery. They come with 264 amp batteries which is small compared to the yuasa batteries. The rest of the car tends to be very reliable

@jackbell7193 the dealer changed this one as under warranty so couldn't say how easy it is maybe some one has and can let you know cheers

@Wolves1963 The last time I saw her was 2 months ago in her local supermarket and hadn't had any issues. I've not seen her since, so I can't comment if I do ill post up cheers

@Hasmilton spot on, that is a big contribution factor with having such a small 12v battery. If they had fitted a more powerful battery, these issues wouldn't be as bad, hence why I recommend fitting a more powerful and battery quality 202 battery

Someone else mentioned that. I no longer have the launch battery tester as it wouldn't work on my phone, so I sold it. 👍

@@azerotha4531 right on, thanks for the informational videos on these things. I can’t believe the difference they read from brand to brand. I would have thought they’d all have been much closer to the same

@TalkinTools it is crazy how much there is between Testers the tester that got me thinking was a topdon BT300P as it failed 90% of batteries, even brand new ones came back as a fail.

@@azerotha4531 yeah that’s pretty ridiculous, and to have both topdon’s be so close to each other make one believe that it’s not just a fluke but they design them to read like that. I ended up getting the launch because I have a launch scan tool already but I looked for the sealey and couldn’t find one readily available

@TalkinTools the launch is good just wouldn't work on my phone lol, the sealey seems to be UK only, it's also branded as DHC BTW300 both are the same tester just different App's
