Hisewen CR123A Rechargeable Batteries 8 Pack, 3.7V 123A Lithium Batteries with Charger for Arlo Camera VMC3030 VMK3200 VMS3230/3330/3430/3530 & Flashlights & Headlamp

So far this system has been great. Batteries have held up well. No discharge and no memory building...at least for now. Other brands I've tried have quickly discharged and lost capacity very fast. Charger works well. No problems so far.

Perfect item as describe thank you

In helping with the environment, the batteries are durable and easy to charge and the charger fits well in a drawer when we are no using it.

These are lithium prismatic cells in a cr123 housing. Batteries charge up to 4.2v instead of the 3.6v of a standard cr123 primary cell. These batteries are also of fairly poor quality. After 2 weeks of cycling through all of them, already had 2 failed cells at the 8th cycle.Also the batteries cannot handle any severe shock, for example if you use them on a weapon sight, when the weapon goes off the cells almost instantly fail. I think the internal BMS fails in this case.On the other hand, the charger works well though. The charger LEDs are so dim, you can barely see them, but the device itself works just fine.

i use it for smart door lock and the battery died within one week, and somehow my lock cant detect how much battery left, it always shows full capacity so I couldnt change the battery on time.dont buy this product but if you do, make sure dont put them into door lock or one day you will be locked outside

The batteries work great, I'm using them for my flashlight. Great product.

I'm glad this size was available in rechargeable batteries. So far so good. Works great and it wasn't too expensive.
