Ansmann AA Rechargeable Batteries [Pack of 8] 2850 mAh NiMH High Capacity AA Type Size Battery Digital Equipment's, Cameras, Flash Units, Speakers, Microphones, Silver

These batteries are incredible. They just keep running and can deliver good levels of current for vintage remote control cars like Tamiya quick drives which use 8x aa batteries

These are the best batteries I've ever used. We use these for powering underground caving lights, where we need reliable and robust batteries you can trust. They last a LONG time, and are by far the most reliable batteries we have ever used. I also use them in infra red night scopes fitted to my rifles for shooting at night - again, they power the scopes for MUCH longer than any other make (By a factor of 2) and are totally reliable. I will never buy any other make than these - Buy some now - you wont regret it.

If you have an application where these batteries are sitting in a charger and go straight into the device, these will just keep going, and going. They're the pinnacle of NiMH and easily hit their 2650-2850 mAh spec after a few cycles. And they will keep that for many, many cycles. I've confirmed that with my own charger (both with charge and discharge tests) and all four of the pack I got are well within spec. This is the second pack of these I've got and those were within spec too - and still are. Some reviewers have clearly been unlucky but I haven't yet.Aside from that, they can take a 1 A charge and easily handle high current applications. Want to draw 3 A from them for 45 minutes? No problem, they'll do it. Most other AA-size batteries won't.Problem is, the self discharge is, like most "original" NiMH designs, pretty bad. Most people don't leave their batteries on the charger. These batteries will lose charge pretty quickly sitting around, especially when freshly charged. Ansmann - and other manufacturers - make low self discharge now that have lower mAh but you'll get to actually get to use most of it. Unless you absolutely need the maximum mAh from batteries, I'd consider those instead.

One problem with sets of rechargeables is nearly always one weak cell amongst the four that does not hold its charge for long.My sophisticated battery tester, and other chargers with diagnostic and discharge - recharge function can ease some issues. Evaluating a set takes time which is the reason for my delayed. response. This is a real bug-bear when using sets of four in portable flash guns.I have had over two decades of experience with rechargeable AAA and AAA cells and switched to Ansmann back in the early noughties (with 2200 and then 2400 mAh - greenish finish) on grounds of improved reliability. However on switching to later 2700 and then 2800 mAh types I am experiencing weak cells in any batch of four. The 2700s I purchased around the start of this decade are now not that reliable when it comes to holding charge.I purchased three sets of 2800 mAh a couple of years back (one with an Ansmann Photocam III charger) and had issues with weak cells recently so purchased another three sets just this last month, one set again with an Ansmann Photocam III charger. I have three other Ansmann chargers of different types, one a rapid Digispeed 4, one an Ansmann Powerline 4 (which also has a discharge - recharge function) and an Ansmann energy 4 which has cell diagnostic feature.I have also used other manufactures cells of similar charge values and these suffer from similar inconsistencies.I imagine a factory somewhere, probably China, churning these out and simply putting different makers labelling on from one week to the next.

We use them in a portable DAB radio which resides in the Bathroom. A single charge will last comfortably one week!

I've used their AAA and AA batteries for a while now, so do feel I can say something sensible about them. They're good, yes, but they're no better than their main brand competitors including Ikea's own brand, all of which are considerably cheaper. I won't buy again.

I have purchased many AA Rechargable Batteries over the years as I am a professional Wedding Photographer somy Flashguns eat up charge in a battery over the day. The last set of batteries I purchased were gold & black you know the make, but did not live up to expectations. So as some years ago I used Ansmann batteries and they worked well but only lasted two seasons.I have only used the batteries for a couple of weddings but after the wedding evening finished the second set stillhad charge left, so well done Amazon for selling this product at a competative price.

We do go through quite a few AA batteries in our household for all manner of things, so I bought a few packs of these two years ago, and they did OK for about a year. I glossed over minor annoyances e.g.; the high price for a pack of 4, the optimistic rating of 2850 mAh (really?) and the fact that low-drain stuff like my Apple iMac's wireless keyboard nor mouse never showed 100% charge after freshly filled via the Ansmann charger I also bought.Over a year ago, the batteries started one by one showing up faults, with an error display on the charger. Once these errors showed up, there was nothing I could do to get them to recharge. I switched to the rather cheesily-named EXtreme 2900mAh AA batteries, which up until now have worked a treat, hold more charge, and work out at less than half the price of these.Meanwhile I am down to my last couple of Ansmann AA's. I shan't be buying these again.
