## Description

Product description

Review: Awsome Buy - these batteries are fantastic. They charge in a small amount of time. The performance is outstanding. I use them in the church wireless microphones. Have no power failures. I haven't had to recharge them for two week ends, and they still show 75-85 per cent. The charger is really easy to use.
Review: Falls short on capacity, but otherwise good. - First up is the matter of rated capacity. Note that these batteries are rated in mWh, not mAh like NiMH rechargeables. A typical 1900mAh NiMH is around 2280mWh. With these rated at 3600mWh, they should have significantly higher capacity, roughly equivalent to 2400mAh. Being lithium, they should also behave better at cold temperatures, and will also endure more charge cycles. As for actual tested capacity, the average across all four cells was 3160mWh, quite short of the 3600mWh rating. This is roughly equivalent to 2110mAh at 1.5V. I obtained this by charging the batteries until full, using the included charger. I then discharged them through an electronic load at 250mA, which is very low and should give a best case scenario as energy lost to heat will be minimized. The highest was 3228mWh, and lowest was 3104mWh. Unfortunately, the current delivering capability isn't quite there, either. I don't see a rating given, but was only able to get about 3.3A out of them before the overcurrent protection stepped in. NiMH cells can usually give 4A or 6A no problem. Indeed, when I tried these with my camera flashes (Godox TT350S, relatively small ones), they failed to prime and showed a low battery symbol. Disappointing, because that's one of the uses explicitly mentioned in the details. They'll work for a lot of other devices which don't demand as much peak current, though. Charging must be done with the unit included in the box. It feeds 5V to the battery, which steps it down internally. You can't stick these in an ordinary NiMH or lithium battery charger, nor can you put other types of batteries in this charger. That's a little bit of a bummer, but understandable. Thankfully, it instantly rejects NiCD/NiMH batteries instead of trying to charge them at 5V. On the plus side, USB-C charging is implemented correctly, with the charger having the proper 5.1k pulldown resistors to request power from a USB-C charger, even when using an e-marked cable. Its build quality is also great. These deliver the full 1.5V until they are depleted. Unfortunately, that means the battery meter on your device will read 100% until it suddenly shuts off. That's common amongst all of these rechargeable lithium AAs, though, since there's a step-down from ~3.7 going on inside. Overall, I'm still pretty happy for the price. They're still highly useful in most devices which eat through AAs, just be aware they won't deliver as much current as alkalines or NiMH rechargeables. Not many devices need that much, but it's worth checking first.
