They say you aren't supposed to use rechargeables, but the August wifi smart locks go through batteries too fast. Granted, these don't last very long, much shorter than disposables. But I'd rather swap these out every month, than have to buy a new set every 3. I've had a set of these for over a year, and sometimes they last longer than others, which I believe has more to do with the locks than the batteries themselves. I recently added a 3rd lock and bought another set of these batteries just to be sure I always have plenty on hand. Definitely have saved me money in the time I've been using them.

Nice little charger, shows a bar graft of battery percentage for each of the 4 charging slots. Not all batteries need to be installed into the base to charge the rest.

No complaints here I use them in my.thermal rifle scope

Really liked the batteries capacity and the charger is quick to charge the batteries. Very good quality and fast shipping

Works great with ArloLong lasting before having to charge

Best delivery as directed best product

This charger works great.LED screen indicating the charge status certainly helps with the progress.Included batteries (X8) work fine and seem to charge good. I have not had a chance to cycle them so I can't attest to the longevity nor the battery life.It comes with a micro USB cable but not a power block. I have a USB charger handy but this kit would been complete if they had included one.I only knocked 1 star due to the missing (?) power block... which most people probably have a few lying around the house... but for the price, I think it would been nice.Other than that, this is a good kit.

Fully charged to dead overnight... save your money and buy real batteries.
