Amazon Basics Rechargeable AAA Batteries, 4-Pack, 800 mAh, NiMH Performance Batteries, Recharge up to 1000x Times, Pre-Charged

These are great. The biggest problem I've had with these rechargeables is keeping everyone else in the household from throwing them away when they run out of juice. Yes these are the 1.2 volt so some electronic stuff doesn't like the lower voltage but they do last good. I checked the MAH rating on a BT-C3400 battery analyzer when they first arrived and sure enough they tested a little higher than the advertised capacity. Amazon has pretty good batteries.

Love these! Saves us so much money and they hold charge for a good amount of time. No more wasting on disposable batteries, and I am sure they'll last long enough to pass down the family tree!

I have been using a Panasonic charger and Panasonic batteries but the Amazon are just as good in every way. They last as long as the Panasonic and charge more quickly. No failures. Standard size.

Addendum 04/29/2025. Just got another set on a "tax free weekend" and all cycled/refreshed fine and charged to 800-850mAh. No duds. These have always been dependable and I expect the same from this set.Addendum 08-09-2024 - Just took the last two sets of four from the chargers. No duds with the replacement order. After cycling/conditioning them most are showing 875mAh and up [one set in the high 700s but that charger always reads low].Addendum 08-06-2024 - Just received another 24 pack and this one has four "duds." I like to condition or cycle my batteries before using them. 20 of them worked fine but four of them would not "stay lit" in the charger. All four were from the same little pack of four. I was using a Maha MH-C3000. Two would not start a charge cycle at all. Two others would erratically start a charge cycle such that I could input "refresh/analyze" and then input the charge and discharge currents (I generally use 200 ma for both charge and discharge - low and slow.) I had to wait for the two erratic ones "came on." After waiting 30s to a minute they did start. I tried the slots with some old working batteries and they "came on" immediately in the same slots so - not the charger. Both batteries would eventually come on and I could input refresh and the current levels but would then not stay on. The screen would go back to its appearance when no batteries are inserted. After 5-6 attempts with the erratic ones (more with the two complete duds) I chose to exchange them. I'll still buy these and I have had the occasional dud or two in previous packages but those would eventually start and cycle in the charger and have been dependable enough over time (see below). The four in this set would not even let me get through the first step. Amazon is great at taking things back so I'll still take my chances. More good, than bad but, this was a bad set. PS: I don't use these in high demand situations or in applications where reliability is a concern. For light, everyday use, they are fine. This is first set of fully non chargeable duds.Addendum 05-19-2024 - Just got another 24 pack on a good sale and am starting to use them. In that time I've noticed a continued trend in that these batteries do not last quite as long, charge to the same level, or tolerate a deep discharge as well as other brands. I still think they are a good value for the sale price (otherwise I would not buy them). As long as I can baby them a bit and make sure they do not discharge too low (motion sensor lights too dim) and swap them out a bit more frequently than other brands (Fujitsu, Ladda, Eneloop [Japanese?] and EBL [Chinese?]). I've not started marking the ones purchased last year with dots to indicate the capacity. I add a dot each time the battery falls below a certain amp hour level. I've had a few die altogether and have about eight from last year's sets that are charging to a lower capacity. On a tangential note - I have had good luck with EBL NiCd AAA.PS - they hold up well enough in dollar store solar recharge yard lights. Not as well as the EBL NiCds but some are still going since last June.Addendum 11/27/2023 - I purchased a 24 pack in March '23 and another 24 in June '23. Overall still pleased but the value for price is fading a little. It is now 5 to 8 months later and I'm going to retire two of them as they are now "dead," bringing my total to 3. These last two are giving an error message or null in multiple chargers. In the past, when this has happened usually I've been able to "wake up" the batteries using an Ansmann charger. Not so, today. The total that I can't recharge is 3 out of 48 so, not all that bad, I guess. The ones that I have been able to rejuvenate (around 8 of 48) tend to have a bit lower capacity and are in general "weaker," fading faster than the remainder. The main WARNING here is to not let them drain completely. I've had several drain to a low level and recharge with no problem BUT, if they go dead, it is difficult to bring them back. [I've had a single one go "dead" with the remaining batteries in a light still giving dim light.] If you place them in devices which have a constant drain, don't forget and leave them for extended periods of time. My most recent two were left in a FireTV remote that was used for three days on vacation about a month ago. Light use but left them in the remote.PS - It has been my experience that these do not hold a charge, long term, as well as other Low Self Discharge brands.On the whole, for the price I got, I would buy them again. I now routinely either remove them or rotate them and am having acceptable results. They're fine for everyday use but I would use something else for demanding uses where reliability may be an issue.I was wary but bought because of price per battery. Others here found a couple of "duds" in the mix when they received theirs. I had 4 of the 24 charge weakly the first time with one less than 100 mAh, two less than 400 mAh, and one just over 700 mAh. I placed these back in the charger with the charger set in the "test" (cycle) mode and they all came out over 800 mAh. I had one that on first charge was >900. Overall pleased. Some are going into yard lights and some will go into keyboards, remotes or old Harbor Freight "giveaway" flashlights.Update 06-10-2023. Just bought two more sets of 24 at a really good price. Switching out AAAs in yard lights. I did notice these don't hold up as well as the 1100 mAh EBL nicads in the yard lights. As before, one set had a couple of duds but after a couple of cycles through a smart charger in test mode, they're all >700mAh with most solidly in the 800 mAh range. When this bunch wears out, I'll gladly buy again.Short version. If you get a couple of duds, try putting them in a charger that can "test" or "cycle" them a few times until they come to a full charge - if your charger has that capability.I've used these before and have been pleased with the value.

This is a great product for the price and for a household that goes through Sao many batteries for toys, lights, etc. I have bought multiple packs in the past. They last a while before needing to be recharged.

These batteries work well, last a while and charge quickly. More affordable than most store bought rechargeables. It’s a good choice!

These batteries last a long time

I have previously tested the original AmazonBasics NiMH Precharged Rechargeable Batteries (in black wrappers) back in 2011. Recently I purchased a set of those new AmazonBasics NiMH Pre-Charged Rechargeable Batteries (in white wrappers), because people kept asking me: "Are those rebranded 1st-gen Sanyo eneloop batteries?" Based on my observations so far, the short answer is "NO". But wait, don't leave yet!I measured the capacities of those AmazonBasics AAA batteries, using my La Crosse BC1000 charger. Here are my findings:- Right out of the package, the average remaining charge is 562mAh, or 70% of the rated '800mAh' capacity.- After one recharge/discharge cycle, the average capacity jumped to 797mAh.- After another 2-3 more cycles, the average capacity leveled off at 821mAhThe above behavior is consistent with my previous test results for original (1000-cycle) eneloop, 2nd-gen (1500-cycle) eneloop and 3rd-gen (1800-cycle) eneloop cells. Note that just as in this case with AmazonBasics cells, all eneloop cells are charged to around 70% when they left factory.Based on electrical characteristics, I believe that those white AmazonBasics cells are indeed rebranded Sanyo eneloop cells. But it is impossible to tell whether they are in fact 1st- or 2nd-generation eneloop. This is because to the end-user, there are no measureable performance differences between 1st, 2nd or even 3rd-generation eneloop cells beside their cycle life claims.Because of the '1000-cycle' claim, most people would jump to the conclusion that white AmazonBasics cells are equivalent to 1st-gen Sanyo eneloop. My closer examination, however, suggested that they are more likely to be rebranded SECOND-generation eneloop instead.Please refer to the picture I uploaded to 'Customer Images' section. Look closely at the positive terminals of those three types of batteries, and you'll notice the difference in their so-called 'vent holes' (the name is misleading because those openings are not actually used for venting):In the case of AAA cells:- First-gen eneloop AAA cell has triangular-shaped vent holes- Second-gen eneloop AAA has vent holes with rounded tops- White AmazonBasics AAA has vent holes with rounded topsIn the case of AA cells:- First-gen eneloop AA cell has triangular-shaped vent holes- Second-gen eneloop AA has no vent holes- White AmazonBasics AA has no vent holesTherefore based on their mechanical aspects, I have to say those white AmazonBasics cells are most likely rebranded 2nd-gen Sanyo eneloop cells.Why would Amazon intentionally sell rebranded 1500-cycle eneloop cells as just 1000-cycle? The answer is Price Differentiation. Manufacturers often de-spec a product when it is sold under different brand at a lower price. Otherwise it will erode the market for their higher-priced brand.What if I'm wrong and those AmazonBasics cells are 'only' 1000 cycles? Well, you could find out the difference in... TEN years. So for now, just pick whichever brand is on sale and be happy.
