10 reviews for Amazon Basics C Cell Rechargeable Batteries 4-Pack, 1.2V (5000mAh Ni-MH), Pre-charged

  1. Macgravy

    Update on 7/27/21 for tests on 6/11/21 (Or about 1 year after original review) Batteries 1-3 have been insalled in a 3 cell Maglite for the year. This flashlight has a cheapie LED lamp. It is of the original Mag light design, not the newer ones with LED lamps. There was little use on these batteries. The light was tested for 5-10 seconds each month just as a battery check. These were discharged to check remaining charge. The discharge ranged from 9052mAh to 9724mAh. Which comes out to 90.54% to 92.74% remaining charge from their rated 10,000mAh. Once again, these batteries are testing out very nicely. They charged up to between 10830mAh to 11660mAh. The internal resistance measured out between 15-19 milli ohms. These 3 batteries also show low self discharge characteristics.Update on 7/27/21 for test on 3/21/21. I took Battery #4, which has been sitting in a drawer for 9 months. So this is a 9 month shelf life check. I discharged & charged the battery. The discharge after 9 months was 9230mAh. That is down ~7.9% from the rated 10,000mAh. So far this is fantastic and does show that at least 1 of the 4 batteries has low self discharge characteristics. (This battery measured 15 milli ohm of internal resistance)This review mirrors my review of Amazon Basics Size C NiMH batteries.I received these on June 21, 2020. I let them sit for an hour to acclimate them to my environment. Reading the instructions/paper work that came with these, you are to charge the batteries at least once every 3-6 months. (This does not give me any warm fuzzies about Low Self-Discharge characteristics of the batteries)Now this seems to be in opposition to the web page which states: Long battery life, extremely gradual self-discharge; maintains 80% capacity for 24 months. (This does give me warm fuzzies about Low Self-Discharge characteristics of the batteries)But what is it….6 months or 2 years. Time will tell. Hopefully I will be alive to report on this and Amazon accepts my added review, which they do not accept very many of my reviews for some reason.Now for early testing: I used my IQ338XL charger for the tests. Set it to charge test, which first discharges the batteries, stores the discharge current/time/internal resistance, then it charges the batteries, stores the charge current/voltage/time/internal resistance…..and when all batteries are finished, the charger flashes the display. This charger is preset at 500 ma discharge and can not be changed. So it will take a very long time to completely discharge these size D 10000mAhr batteries, especially with a full charge. On charge, this charger current is selectable…500, 750, 1000, and one level higher, which I can not recall. I set the charge current to 1000mA.Upon completion of the testing all of the batteries were between 1.45 and 1.46 volts, 10830mAhr to 11660mA and 15-22 mOhms internal resistance. These batteries came with a charge of 9052mAhr to 9724mAhr, which is 90.52% to 97.24% of the rated capacity. This is fantastic.To completely discharge the battery with 11660mAhr charge capacity at 500mA load current would take around 23 hours…..So, be prepared for the time it takes. And then it has to charge them…and at 1000mA of charge current it will take almost 12-13 hours. So basically a day and a half to do 1 cycle of discharge/charge.These batteries were dated December 2019. Now for the warm fuzzies of Low Self-Discharge…..It is now the 3nd week of June 2020….so lets just call it 6 month shelf life and they came with 90 to 97% charge…WOW…how can this be true??? I have never had this much charge left in any battery after 6 months…but the again….how often does Amazon charge them while on the shelf…no one really knows.Well, time will tell.

    Out of the box tested to near 10% OVER capacity. Very happy with these. I will comeback and update if they fail to maintain such great capacity but I really seem to doubt I will have problems.

    First thing’s first, these AmazonBasics D batteries are made CHINA (as of June 2020). However, on the first capacity test the two cells that I tested were right around the 10,000 mAh capacity rating. This is very impressive, since in general NiMH/NiCd cells need a few charges to reach max capacity. Since they take so long to test I wont do a second run, but the capacity would probably go up another 5% if I did, which would give them amazingly high and honest capacity. They also came about 85% charged, which is nice.One thing to note is that they are slightly taller than normal D batteries. About 30 thousandths of an inch taller (0.030) To be exact. Not sure how much this matters. The contact surface on the positive end is also smaller than a normal D battery, with only the dimple being metal vs the whole top.Overall, while I picked Energizer for my AA batteries due to them being made in Japan, these AmazonBasics are the only good high capacity brand for D size batteries that I could find.

    In the past, i have purchased and tried different brand batteries of various sizes. I have tried EBL, Eneloop, Panasonic, Duracel and Amazonbasics. Being the father of 3 kids makes you find the best batteries for a buck out there. Kids need batteries for their toys and devices. Dont even get me started on baby bouncers and rockers. You may have to keep charging the batteries every day and keep them in rotation. I can honestly say this, Amazonbasic batteries are pretty good. In par if not better quality wise than other brands, but when it comes to the value, Amazonbasics win hands down. I’ve had some of the AA and AAA batteries for years and they still hold a charge and charge pretty fast.One thing i should also mention is that the bigger EBL charger i have shown in my picture charges the batteries way faster than other chargers i have tried, Up to 3 times as fast as the Eneloop set comes with.Take it from someone that tried these brands and have used them for years. These batteries are pretty good! I can confidently say that AmazonBasic batteries are the best rechargable batteries for the value.Please, if you found my review helpful, click the thumbs up button below.

    Knowing what I know now, batteries are always going to be hit or miss. I can use multiple sets of Duracell batteries and one set will last twice as long as the other set. Now, with the set that I received here, I use it on a trash can sensor, they’ve lasted more than 2 weeks so far so I’m happy about that. One thing you need to make sure of is, don’t use the batteries until it’s out of juice. If you do that too much, it’ll stop recharging, the way to fix this is you’ll need to touch a good battery with a bad battery on the + ends of the battery, then have a metal wire touching both -(minus) ends for 30 seconds which will give it a bit of charge so the charger recognizes the battery.

    Who needs 9 volt batteries anymore? Well… in the ‘old days’, almost everything that ran on transistors needed 9V batteries. Theses days, almost everything runs on 5 Volts, from a simple USB connection — charger, computer, adapter, etc.But… I have an old (about 1995?) lawn sprinkler timer/controller and IT needed not only a 9 volt battery, but… it needed a Ni-Cad RECHARGEABLE 9 volt battery! Very rare item, indeed! The sprinkler timer has its own power supply of 26 Volts AC from an old adapter you plug into house 120 volt AC outlet. But… IF that input power ever fails, the sprinkler timer needed something to keep its programmed memory alive until power to you house was restored! So… they install a rechargeable 9V Ni_cad batter to keep the memory alive so you don’t have to re-program it in case of a minor power failure to your house.All that said, these are a great bargain for the 9V Ni-Cad batteries! Best deal you’ll find here on Amazon. And… they arrived immediately, the very next day! Can’t beat that!

    I bought a 4-pack of  AmazonBasics NiMH Low Self-Discharge C Cells  in 2019 Oct for standby service: they’ll allow extended use of my 2 C cell flashlight in case of prolonged power failure or other need. Note that when I purchased, the product page did not make any mention of low self-discharge; I inferred and hoped that would be the case, and it has proven so. The product page was later updated to mention low self-discharge. The cells I received had been manufactured in 2019 Jul. Note the manufacturing date was (lightly) stamped into, not printed onto, the labels. Favorable lighting angle and a bit of scrutiny (OK, I “cheated” and used a magnifying glass…) can be required for reading. I used an  AccuPower IQ-338XL battery analyzer  to test the cells on receipt and again after about 16.5 weeks of storage. The results have been excellent, implying these will serve my purpose well. The comparatively low price is a nice bonus. On receipt, the cells delivered an average of 3.6 A*h, about 73% of their rated 5 A*h capacity. Maximum cell-to-cell variation was 4.5%. Freshly charged, the cells delivered an average of 5.2 A*h, or nearly 104% of rated capacity. Maximum cell-to-cell variation was 4.8%. After about 16.5 weeks storage, the cells delivered an average of 4.6 A*h, about 92% of rated capacity. So yes, they are indeed low self-discharge (LSD) and exhibiting very good initial charge retention. Note that LSD NiMH cells typically exhibit higher self-discharge in the initial weeks after charging before settling to their longer-term much slower self-discharge rates. These cells did a nice (excellent?) job of initial charge retention. Oh, and maximum cell-to-cell capacity variation was 4.7%. Nice. The cells accepted in the range of 103% to 111% of rated capacity when charged from “empty” (had been discharged to about 0.9 V/cell), and my IQ-338XL had no difficulty properly terminating charge of any of these cells. The small differences between accepted and delivered capacities show good efficiencies at the modest currents (500 mA discharge, 1.5 A charge) applied via the IQ-338XL. So, my testing has shown these are just what I wanted and they’re working well.

    One of the problems with rechargeable batteries is that they lose their charge over time if you store them, so when you need a fresh one you have to take the time to recharge it. Not so with these. I bought them Aug 2020, charged them all up, used one and put the rest in my desk. The one I used was in a laser thermometer that I use maybe two or three times a week in the kitchen. I just had to recharge that battery after 5 months. I check the other 3 and they are still fully charged. 9v batteries aren’t cheap so 4 batteries for $13.99 is a good deal in relation to the performance.

    I replaced the lead-acid batteries and incandescent bulb in my old Maglite with these rechargeable batteries and a CREE bulb. The result is totally awesome. The flashlight is really bright and batteries rarely need a recharge. I walk my dog every night so it gets a lot of use and they are holding up great.Things I absolutely love about these batteries:- These are totally guilt-free and hassle-free. Disposing of the dead lead batteries was always a huge nuisance. Either I throw them in the trash and feel guilty about contaminating the environment with lead or I try to find a place that recycles lead-acid batteries and drive to wherever that is. Then there was the pile of dead batteries in the closet waiting for me to get rid of. Best-buy recycles rechargeable batteries (but not lead batteries) so if I ever have Ni-MH batteries go bad (never happened to me yet) they will be easy to get rid of.- These Amazon Ni-MH do not destroy equipment by leaking lead and acid. I have never had a Ni-MH battery leak, and if one ever did it should not be destructive. Even the expensive brand-name lead batteries like Duracell and Energizer ruin equipment by leaking. Also, lead is extremely toxic and causes mental retardation in children, so who wants that spilled all over? Not to mention the acid burns, which suck for everyone and especially for children. Get these Ni-MH batteries and just so no to the lead batteries.- It’s way less expensive to buy these batteries and recharge them than to buy lead-acid batteries and dispose of them.- These rechargeables at Amazon are cost less than paying grocery-store prices for lead batteries. Plan ahead and order a few spares to keep on hand.

    These are very good quality 9V NiMH cells when compared to one of the pioneers, Tenergy 9V NiMH LSD, analyzed new out of box.ProsCame fully charged, using a battery analyzer all cells exceeded 180 mAh eachManufacture date is stamped on each battery, mine are Jul 2019. This reinforces they are fresh as aging deteriorates the packISO protocol battery analysis of 100mA discharge confirms that each pack stores >= 200mAh, actual was over 10% each. Each pack was within 5% of each other, very close toleranceGood build quality, excellent label on the cells, marking, and connectorsBy contrast, new 9v LSD NiMH I bought from another maker 10 years ago had none of these Pros except the last. Those packs suggest inconsistent manufacture, and only half of that batch of 9V work like new.ConsSlightly bigger than standard 9V and could be a tight or a no fit for some devicesNo data on self discharge rate, or expected calendar lifePlease note all types of 9V are actually battery packs, not individual batteries and should be treated as a NiMH battery pack, that is NiMh cells in series, otherwise you won’t get the expected life in years of the pack.A pack should be kept fully charged, as the discharge rate of AmazonBasic 9V LSD are not known, its best to recharge these once a year, even if unused. Used packs should be charged up as soon as possible, if left in the discharged state it increases the risk of reverse discharge to some cells in series. This is because all cells have a self discharge rate, albeit small, but when in series, the weaker cells in series may be pushed into reverse discharge, and hence, over discharged. Also when a 9V is fully discharged, it usually means its at 7V, or about 1V per cell, the low limit before it is over discharged and some cells in the series may not be well made and may already be near or at reverse discharge. If you keep the pack topped up, it almost certainly will not happen. See comments for references.
