Kobalt 24-Volt Battery Output Testing - What Is The Best Battery To Buy?

→ Dewalt 20V Battery Testing - • What Is The Best DEWAL...
----------------------------------------------------------------------
The Kobalt 24-Volt line has some interesting batteries in the lineup. Many of them are very affordable and some are the same Amp-Hour but different sized. For example, we have the 4AH Extended run and the 4Ah Ultimate battery pack. How much difference will you see between those battery packs? From our testing, quite a bit!
We take a new Kobalt 24V drill and watch the voltage dip during different drilling procedures. We can use that data to help decide what batteries are the best to purchase in the future or what ones will work best on heavy-duty tools. In the case of the 4Ah batteries in the Kobalt 24V line, the Ultimate series is by far a better performer if you can find them at a good price.
The Kobalt 8Ah Ultimate battery is a large battery and might be a lot for a drill, but it was awesome at keeping the voltage high and giving the tool the most power to complete any task.
Many people will say that Amp-Hours have no relation to power, and in some ways they are right. The issue is what cells are used in the different amp-hour battery packs. The Amp-Output ratings on these cells are different, so in most cases, a 6Ah battery will outperform a 5Ah battery. But in other cases, a 6Ah battery might outperform a 9Ah battery. So looking at the Ah alone is not a determining factor.
The goal of these batteries is to provide the amps the tool is looking for and if it starts to fail to do so, the voltage will drop. We will see this the most in smaller compact battery packs.
Leave us a comment below as to how you feel about this testing and if you were surprised by the outcome.

For the money it’s hard to beat the performance of the Kobalt 24v lineup. Thanks for doing this test!

[@doug667]

Agreed, those 8ah Kobalt batteries are terrific. They improve the vacuum performance noticeably. I hope Kobalt continues to update the line with new tools.

[@J.Wick.]

Kobalt! Happy to see this video, and the testing. Best traditional batteries out there IMO. 6 Samsung Cells for less money than the 5 cell 18V brands in a very similar size case. Not to mention a glass fiber case that DeWalt & Milwaukee charge extra for in an 'oil resistant' case. They're outstanding for electronic projects as well due to the cost.

[@stephaneroy8415]

There are 10 cells in 18v batteries i tink

[@J.Wick.]

@@stephaneroy8415 Incorrect. There can be 10. But, it's always a multiple of 5. 5 is the minimum. It's just how they're laid out. 4v (3.6) x 5 = 20v (18)

[@SGAOuTLaWz]

This was a great test. Glad to see Kobalt getting some props 👏

[@puffnstuff12]

Thanks for testing the batteries and showing the output differences. I'm going to have to pony up for some 8ah ultimate outputs.

[@toolswithtim2019]

Great testing - always enjoy seeing the difference in output between different batteries. Convinced me that I need some of the U.O. batteries for my XTR Circ. Saw 😅

[@mistercohaagen]

I can run my lawnmower with 2x 4AH Extended Run for like 40 minutes. They're not bad at all. I put in lag bolts for a wall-mounted workbench, and I can jack up my car and remove struts all with the standard 2AH (scissor jacks with drill, 1/2" impact wrench for rusty suspension bolts). Even their cheapest batteries are amazingly capable.

[@dragon76er]

Awesome test🤙

[@jlousy1901]

Subscriber here! I think you're on to something with this battery load test here! would love to see this same test on other manufacturers, specifically Ridgid and their various batteries. Great vid!

[@jacksmith2315]

Ya id love to see this w the regular gen5x 4ah vs the octane 3ah vs the max output 4ah. Then gen 5x 4ah i bet are shit w the octane 3ah being the best since its the only one w 21700

[@ju2067]

Great review. Very helpful!

[@sneeks253]

Thanks for info very much appreciated

[@southsidetom]

I use either the 2AH or Ultimate 4AH. 2AH on impact for most tasks due to light weight. Any saws use 4AH Ultimate. Nice video!

[@jupiter_thawk72]

Very cool ! Thanks for you’re Time

[@stephaneroy8415]

That was usefull , thanks a bunch.

[@MrRubenrivera9649]

The same people who make kobalt make flex and Menards masterforce brand power tools. Good video and review of the battery power comparison I was impressed on how they performed.

[@ericnichols9275]

Would love to see you test the FLEX HAMMER DRILL with the STACKED LITHIUM for power drop 3.5 VS 6.0 VS 10.0

[@SnakeAndTurtleQigong]

Thanks so much

[@nolove5062]

I have the 2 pack of the 4amp high out put battery can hear the difference in it between the extended run battery

[@ccbowers]

Interesting that the "Tools Tested" channel had the 4Ah HO battery testing worse than the standard 4Ah on his dyno. He tested speed and power on the drills on the dyno until it reaches max torque then stops. Channel is quite good, although that result does seem odd.

[@jonspitzley2801]

Good video👍✌️👊 I like my kobalt tools that I do have

[@ARCMASTER1130]

I run my mower with 2 8 amp ultimate batterys,and the power gain is noticable

[@JJ20kil3r]

Both my ultimate outputs shit the bed around the same time and my extended runs are still going strong

[@olgajoachimosmundsen4647]

Hey, how does the flexvolt advantage joist drill compare to the hammer drill in power? Is the difference big?

[@tanthadcork5040]

Can You do this type of video on Milwaukee's M12 batteries testing the differences between the standard and newer high output packs?

[@WorkshopAddict]

Will try. Getting the connection there might be harder.

[@tanthadcork5040]

@@WorkshopAddict Its worth a try.

[@ajmedeiros77]

The 8 amp hr battery is on sale for $99 bucks right now. Best deal on any battery. Love all my kobalt tools and are the best deal for the money. Have had and seen too many dewalt and rigid catch on fire or go up in smoke.

[@MinnesotaBeekeeper]

Interesting. Would love to see some reviews on generic replacement batteries.

[@orijimi]

It's a weak market for knockoff Kobalt batteries because it's a less popular/regionally limited brand and the legit batteries are so affordable.

[@Freedomring1836]

This test would be interesting to see on something like a circ Saw or impact. Maybe try this on a Kobalt 7in Saw and impact driver?

[@stephaneroy8415]

I agree with you , this is when more power makes a huge difference.

[@stephaneroy8415]

IM having a hard time choosing the right battery , maybe you can help. I can get the newest 4ah battery and a 6Ah from previous generation , both for 99.99 canadian. Based on your test , i beleive i'm better off with the 6ah , cause of more stable voltage and recovery time and overall battery capacity , but newer can deliver as much power for short period of time while draining faster in those conditions. My real concern is that i read that 21700 cells are rated for 250 cycle life charges wich is low compared to the advertized 500 cycles for 18650 cells. What's your opinion on this?

[@gcoffey223]

Just started getting into ryobi

[@gcoffey223]

Just started taking back my broken ryobis... for the 2nd time. Got refunds. Now I have Kobalt jigsaw and 18 G nail gun. They feel so much better, and have plenty of power

[@chrish5018]

Nice battery review. I would’ve loved to see the output on that Gardenjoy drill driver you burned up a little while back.

[@Benjbugarin]

Hi. What difference would there be. Compare a 4amp extended to 5 amp extended run time kobalt 24v batteries

[@WorkshopAddict]

Extended runtime is a marketing term. Maybe you get 21700 cells over 18650, but amp hour is amp hour, so a normal 4 amp hour battery would have the same runtime as a 4 amp hour extended runtime battery.

[@troylat9568]

I bought 2 4ah 24v batteries and both are not charging full .. it's like they have cell damage .. thing is bought these while I was in new york now I'm out the country and can't return them

[@damienmcelveen5124]

I need help I’m looking to use my kobalt batteries to run a fish finder and I need to use a buck converter to reduce the bolts from 24v to 12v also the fish finder needs atleast 10amps to run

[@damienmcelveen5124]

Or is the 24v kobalt not a true 24v?

[@ericjones9844]

What about just for screws? Does it make a big difference?

[@james2042]

Any should be fine for small screws. Actually it's probably overkill

[@PrximaCentauri]

How do you think the 6ah extended run would’ve done?

[@WorkshopAddict]

I wish I could have had it for this, but based on the name, Extended Run, I assume it would have done better than the 4Ah ER, but not much.

[@PrximaCentauri]

@@WorkshopAddict gotcha, great video! Would love to see a good review of the new kobalt 24v wet tile saw if you could find one.

[@fusonbradly]

I'd say it'd be close to the 4ah uo

[@KevinmSilveira7]

I like The ultimate battery's but I've had bad luck with them they begin to not want to charge

[@roberth3793]

I've had two of them do that.

[@KevinmSilveira7]

@roberth3793 yup its not good

[@ladyshiva69]

can i use a dewalt or craftman battery on a kobalt

[@WorkshopAddict]

No. Each brand has a specific battery.

[@DanielGomez-cf6vk]

Love kobalt but not buying anymore it’s my favorite for the pole saw and chainsaw no tools required to replace chain fastest blade change on those

[@lenk8374]

I'm not seeing their 5 and 6ah

[@ProxyFinal]

better than Ryobi in terms of value.

[@orijimi]

The more important point is that the tools are better designed, especially before the HP line. Albeit, as if we've seen on the channel, there's reliability issues with some of 'em. But the real delta between Kobalt and Ryobi is the number of tools on the platform.

[@gcoffey223]

My ryobi jigsaw brokebin 4 days. It's replacement broke about 2 weeks later. My ryobib18G nail gun broke in 9 days, it's replacement started acting up about 2 weeks later. Now I have a kobalt jigsaw and ryobi nail gun. Very happy with Kobalt. They feel solid

[@dan260140]

I think kobalt is a very underrated brand. Kobalt > Ridgid

[@AR-hj7sm]

Nah if ur only getting a 3 year warranty milwaukee always better

[@boosted2.4_sky]

Ridgid is better than Kobalt in many ways...☝️

[@sumolax22]

@@boosted2.4_sky what ways? Kobalt takes the cake in power and price. The XTR line is way better once they expand it some more

Absolutely
