  • Rechargeable batteries tested for low self-drain or self-discharge. Eneloop, AmazonBasics, IKEA LADDA, Energizer, EBL, Harbor Freight Thunderbolt, PowerEx, Rayovac, and Duracell tested. Additional cells added to testing: Varta and ActiveEnergy (Thank you Tony for sending them to me all the way from Australia). Tested capacity after 25 days of use in exterior, solar-powered lights.

    Many thanks to everyone who requested this video! Rechargeable batteries are known for self-discharging while not in use. So, is the Eneloop better than AmazonBasics NiMH AA battery? The IKEA LADDA, Energizer, EBL, Harbor Freight Thunderbolt, PowerEx, Rayovac, and Duracell were also tested. I also tested 2 new batteries, the Varta and ActiveEnergy (Thank you Tony for sending them to me all the way from Australia). Finally, I measured the capacity of the batteries after 25 days of use in exterior, solar-powered lights. Please keep the video ideas coming. 100% of Project Farm videos come from viewers. Thanks again!

    It's been seven months and I still keep coming back to your battery videos. They're so good! Can't wait for the update video on the rechargeables 😁

    How are the batteries holding up? Interested in an update since last video. Thanks

    I'm really impressed by the Ladda batteries. High capacity and still managed to hold charge really well! I normally use a lot of EBL's and from what I can tell, the 2300's might hold charge longer. It looks like the classic "high capacity means high self-discharge" might hold true for the EBL 2800's. But that doesn't explain how those damn Ladda batteries performed so well!

    Hello from NYC, I have learned a lot on items we use frequently. Can you please explain what may means? How charging on a lower mAh effects rechargeable batteries? Difference between the nmih & lithium rechargeable batteries differ and the best WAY to CHARGE them? Thanks Chris NYC

    I've owned the EBL brand in AA & AAA, purchased from Amazon 12 AA & 12 AAA set during a lightning deal for $18. That was in Nov. of 2016, currently September 10th 2019, so almost 3 years ago. I use them all in various devices like my keyboard, mouse, tv remotes, weather station remote sensor, flashlights and so on. I've never had one sit around long enough to notice any discharge issues. About a month ago I had to replace the batteries in the remote sensor for the weather station, it hadn't been sending a signal for over a week. When I finally decided to go retrieve the batteries and charge them I figured that they may need a refresh so I put them on a Opus BT-C3100 V2 and set it to do the refresh at 500 mAh. The batteries in question are the 2800 mAh AA's that have been recharged around times. The same set has been in used outdoors in the weather station sensor year round in Maryland. The sensor is in the shade about 15' off the ground and subject to temps ranging from around 0 degrees F. to 104 degrees F. Not the ideal situation for any small battery but I usually get 5- 6 months between charges. When I recently did the refresh the EBL 2800 AA's charged to almost 2900. I don't recall exactly but I believe it was somewhere around 2872 mAh and 2887 mAh, well over it's rated capacity. I have noticed that all of the other EBL batteries I use have also increased in capacity. All 24 batteries charge to or above their stated capacity. If there was a way to post pictures I would. I took pictures of completed charges for several sets of batteries, I numbered them all so I could identify which were for which device. I've been very impressed with all of my EBL batteries and took pictures so I could write an Amazon review. I never got around to writing the review but I still have the pics and will write one someday. If I could I'd send you the pics so you could see for yourself.In my opinion the battery cost to capacity ratio is by far the best deal I could find then and now. Yes the Enloop's by panasonic are top of the line but it would cost a small fortune to buy 24 batteries and the same goes for the Energizer. I'd recommend the EBL's to anyone I know!I also use them in items that a battery failure could mean the difference between life & death, in stuff that you don't want to fail if there's an intruder in your home. Another great video.

    Too bad you didn't include the "Battery Plus Bulbs" batteries too! They have two different types.

    No eneloop are absolutely not impressive, they only last 20 recycle's then they are just dead, its the worst i have ever tried.

    Really wish you tested the Eneloop pros, very curious between the eneloop & eneloop pro.

    Those Varta batteries are expensive. A 4 pack costs $30. You should definitely check the long term sustainability of those batteries, but for now I'll stick with Duracell and Eneloop Pro.

    Do you have any videos on socket strength. High dollar,or low,,which one is the best for the money?

    Great idea, just maybe top 3 or 4 performers. Knowing their power rating is close and how many uses we can ACTUALLY get would be paramount at the local (or Amazon) battery station.

    Thanks for the excellent comparisons and testing. I'm very interested in seeing how the longer-term discharge/recharge results pan out. I started using NiMH batteries in, I believe, 2001, and still have a small number of those first AAs that (barely) work. My newest AAs are nearly 10 year old Eneloops most of which continue to work fine although I have no idea how much of a charge they hold. The AAA batteries, regardless of brand, have not fared nearly as well in longevity as the AAs; most have died and the ones that haven't don't last long under load. The worst NiMHs that I've bought were some Energizers, most of which died within 2-3 years.

    Is there going to be a follow up to the discharge part of this video?I would be really interested.

    The two videos you've done on rechargeable AA batteries are great. It looks like it's been 6 months since then... any updates to shelf life and usage cycles coming soon?

    Thanks for testing!! i loved the part about the solar lights. ive got like 40 of them and they all crap out, i was just fixing to get a 48 battery lot from ebay when i saw this video. out of all of them only 2 had defective solar cells. im sure there are alot of people out there that just buy new ones (like me) only to have the same thing happen to the new ones and end up with lights that dont work. the new GOOD batteries will end up costing more than the lights did but all of them came with the crappy knockoff china batteries (purple,green or yellow). thanks for your help... Robby

    I know it’s late but if you still have the batteries I would love to potentially see a 6 month to 1 year update to see which battery keeps the best charge after continuous use

    Are you going to test lithium ion AA rechargeable batteries?

  • mytvchannellock

    I'm curious if it is cost effective to recharge the batteries rather than replace old alkaline. Or AT what point does it become cost effective

    The IKEA LADDA's are by far the cheapest here in Canada out of all the major brands, coming in at <$10 for a 4 pack. Everything else is at least double the price.

    Really good tests. But why missing Eneloop Pro? That's supposed to be superior. EBL did not surprise, it's just a Chinese cheap company, as I know, that doesn't care about quality - only low price and high promises.

    My long term experience with Amazon black & white has been they fail early compared to Energizer and Duracell.

    Did you continue the solar light charge/discharge cycle effects on capacity? It would be nice to see if there's a difference in longevity that way between brands, though I'm not sure a single battery is a large enough sample size...

    The discharge isn’t linear on longer term storage, it starts off discharging lighter then tapers off to almost nothing. Depending on brand the cells will stabilize around the 75-80% range after a few years.

    What's important here is how many times can you charge these cell's.

    Interesting as LADDA, Energiser are rebranded eneloops.

    Is there a rechargeable lithium ion to test?
