Amazon Basics 4-Pack, Rechargeable C Cell NiMH Batteries, 5000maAh, Recharge up to 1000x Times , Pre-Charged

When it said Amazon basics I thought uuh maybe not so good. However I was surprised.Had no issues. Fast charge. Great quality. Use on my radio to save electrice as my programme on Tv I have on is available on the radio and Im too busy cleaning to watch it anyway. This way its like having the Tv on without the power.Yey. They are suprisingly light weight too unlike other bulky heavy batteries.Would definitely buy them again.

Use in my smoke alarms, last well

I recently purchased the Amazon Basics 4-Pack Rechargeable C Cell NiMH Batteries (5000mAh, Pre-Charged) to power the electronic ignition system on my gas fireplace, and I’m so thrilled with their performance that I bought a second pack! These batteries were a perfect fit for my fireplace’s battery-operated control module, which sparks the pilot light and ignites the burner. Right out of the box, they were pre-charged and ready to use, allowing me to start my fireplace instantly with a simple press of the ignition button, creating a cozy ambiance without any hassle.The high capacity of these batteries ensures long-lasting power for my fireplace’s intermittent pilot ignition (IPI) system, which only activates when the fireplace is in use, saving gas and ensuring safety. They’ve powered multiple ignition cycles over weeks of regular use without needing a recharge, and their low self-discharge rate means they hold their charge well when the fireplace is off, perfect for seasonal use. I’ve had no issues with the ignition failing, and the batteries keep my fireplace running smoothly every time. I was so pleased with their reliability that I grabbed another pack to keep as a backup for my fireplace and other devices.The delivery was quick, and the packaging was secure, ensuring the batteries arrived in perfect condition. For the price, these 4-packs are an incredible value, offering performance that rivals more expensive brands. These batteries are a must-have for anyone using battery-operated devices like gas fireplace ignition systems or other electronics. Five stars for reliability, longevity, and cost-effectiveness—I highly recommend these to anyone needing dependable C cell batteries for their home!

I bought these after reading positive reviews that verified their capacity. First impressions were good as they were quite heavy - always a good indicator of battery capacity. On my digital scales the cells weighed about 160g each, which is about right for genuine 10,000mAh 'D' cells.As they were on special offer, I bought 2 packs of 4 to meet the minimum order value for free delivery. All 8 cells were manufactured in April 2020, and they all measured between 1.275v - 1.285v.I put them on charge to make sure they were fully charged before doing any capacity checks. The charge rate was 1 Amp & took about 2 hours to fully charge them all, so they already had something like 80% of their capacity available. Assuming they were fully charged on the manufacturing date of April 2020 before being sealed in their boxes, that's a self-discharge rate of about 20% in 7 months.Initial capacity checks at a calibrated 1.5 Amp constant current discharge to 1v per cell gave around 9500-9700mAh on my test equipment. This is an excellent result for a first capacity check, as NiMHs need several charge/discharge cycles to reach full rated capacity & there's no doubt that they will reach 10000mAh after bedding-in.With the Black Friday discount & free delivery, the total cost for 8 x genuine 10,000mAh 'D' cells was just £33.68. That's astonishing value for money & I can recommend these batteries very highly. Just make sure you give them enough time to charge up properly, as 10,000mAh capacity takes a long time to fully charge.Cheap chargers almost certainly won't even deliver their rated charging current, and you may end up blaming the batteries when it's your charger that's causing the problem. Even a genuine 1Amp charger is going to take all night to recharge a completely flat cell...

Very good value

I was surprised to find that the Amazon C cells were 5,111, 5,008, 5,029, 5,099 mAh respectively on a pack of four. They tested as pretty low impedance too. Yes I dont like that it says "Amazon Basics" on them! But they are one of the few cells that actually do what it says on the tin.The typical C cell that you see on here like the EBL for e.g all CLAIM 5,000mAh. When I tested the EBL C cells they are just 3,200mAh. + or - 25mAh. Thats a plain lie! And this iss after 5 full cycles. No they did not improve much.I have been thoroughly p******d off by the number of cells bought from many different sources over the years that turned out to be totally misrepresented and the capacity being plain lies. They scam people because they can get away with it. Most people never test them. It seems only japanese made cells are any good! Never tested any chinese made cell that met its capacity claims. Some are terrible!These are exactly what they claim to be. 5,000 mAh plus! On cycle 1.Cant comment of the self discharge rate as I only got these a day ago.

I bought these to put in a lantern for the power cuts we are getting, I have high hopes for them

Batteries received were all but flat and as I always charge new battereis first this isnt an issue, just make sure you do the same. otherwise the batteries may get damaged.I was surprised as they are listed as pre charged, however after checking the packaging I see they were manufactured 02/2023 so two years on a shelf which is not ideal and we can only assume that they are stored in adequet conditions.So far I have only tested them for a short while so time will tell if they are quality enough to last and undamaged.Edit.I decided to grade the batteries and check the capacity of each one to see how they had been affected by two years on a shelf and they are not too bad.As long as you dont run them till they empty and recharge them at about 50% they should last many years
