POWERAXIS AA Rechargeable Batteries 2800mAh[8-Pack], Ni-MH High Performance 1200 Cycle Pre-Charged Rechargeable Batteries

Good quality batteries with consistent power and a high mAh, I have been using rechargeable batteries for many years now but have never really fully understood the mAh and the difference between 1.2v and 1.5v with non-rechargeable batteries so before making a purchase I did a bit of research and decided on purchasing these with a good value price and high mAh. I use them in several devices and always keep a box of non-rechargeable batteries on my desk for the children’s toys as experience has taught me not to give them rechargeable as they often get thrown out with the toy when it breaks.They arrived in a little flip top box containing the eight batteries in two separate clear plastic clip lock storage boxes quite neat for storage, these come pre-charged so two went straight into my Xbox One controller, I play every night and my daughter always plays at the weekend and this set lasted over 16 hours play before needing charging which is great as my old set only last around 6 now and a new set of non-rechargeable around 12 hours and then need throwing away.As I said at the beginning I did a bit of research on the differences between 1.2v and 1.5v and the meaning of mAh so for anyone who is as I was and doesn’t know the mAh stands for milli Ampere hour or milli Amp hour and is a measure of the battery's energy storage capacity so the higher the mAh the longer it should last.Non-rechargeable AA batteries normally have a 1.5v standard while AA rechargeable batteries normally have a 1.2v standard, with non-rechargeable AA batteries they start at 1.5v and make a steady decline in power and once they drop below a rate of 1.0v they cease to work depending on the device.Rechargeable AA batteries normally have a 1.2v standard and the drop rate is different they keep at that steady power delivery rate until they are depleted giving a steadier power over an extended period, you can find some products need an initial delivery rate above 1.2v and rechargeable batteries will not work in such devices, I hope this is makes sense to anyone who didn’t know.Summary***********Overall good solid high power batteries with a consistent power delivery that last for ages and are good value, I’m pleased with them.

Two of the handsets in my BT Gigaset three extension phone system were on the blink.My first thought was to buy a new system - as I'd had these for several years.Realising that each handset had rechargeable batteries I decided it was worth risking the cost of replacing the batteries - after all the batteries could be used elsewhere if the handsets still failed.What do you know - the system works fine now.Virtually a new system for the cost of new batteries.

I love these batteries. They charge quickly and they drive my keyboard and mouse14 hours daioy for well more than a week.I love the packaging too, indode the carton are plastic clip-close continers whch are so handy for keeping your space tidy and make storage very easy. With a competitive pricing t hese ae a hsard item to beat. they've taken first place as my prefrred AAA rechargeables and their 1.2 Volt output is great. I can't recommend them highly enough.

Really Pleased with these batteries. They come as two packs of four in plastic cases which is very handy for safe and clean storage ready for use..They were already charged although I did further charge them in a reasonable amount of time. I have not yet had them for sufficient time to check they will recharge a large number of times but I have no reason to believe they will not. I have now used them in a torch and a camera and they functioned without any problems. I was attracted to them by the claim that they will hold their charge for a considerable period even if unused. Many rechargeable batteries deplete very quickly after they have been charged up which is very frustrating if you hold them in reserve them for use immediately the current set are exhausted and they fail very quickly when put into service. They are also valuable as a power source as they are marked as 2800 mAH.

I rarely ever right bad reviews but this is one of them times, these lathable 1100mah batteries are more like 500mah at the most. They last for half a day of mild use - (wireless headphones) if your lucky, used for about 3hs and there dead already. I'm better off getting rid of them and buying some that last at least a day, my last set of 1000mah lasted 3-4 days of mild use. If your buying for TV remote then there OK but anything else there not worth the high price.

These batteries are next to useless. I have an Amazon charger which is excellent and tells me the condition of each individual battery before charging starts. As I have several brands, these are the only ones it tells me are bad after a couple of uses from new, meaning I have already had to dispose of two out of the four. I won't be buying this brand again.

Fresh from the charger these don't last as long as lower rated rechargeables of another brand, Plus if you leave them out for a few weeks they run down..... same with AA & AAA as I stupidly bought loads of them......P.S. I have a BTND in electrical engineering so I know what I'm talking about, These batteries are rubbish!

Using with leds they have a very short life compared to alkaline batteries
