These work well for august smart locks. They go through batteries so quickly. These dont last quite as long as standard batteries, but i get a couole months out of them

Easy to use and charge, comes with cable that hides easily. Have purchased more than 1

Issue: batteries don’t recharge.I bought this for my August lock. On super sale it cost the same as non-recharging batteries so I thought I would try it. The batteries did power my lock for about the same amount of time as regular batteries. However, when I tried charging the batteries on the charger, some stayed red. When I got some to turn green and put them in lock, they didn’t power my lock and when put back on charger they stayed red.Update: once the batteries “charged” I took them out of the charger, waited a day, then put them back in the charger. The batteries read as uncharged, so they charged again, like double charging. I do this each time I charge the batteries and they work in my August lock now for weeks depending on usage.

I was going thru so many batteries for my August smart lock. I bought this to save money on batteries and I don’t regret it. Every time a set dies I just grab the other set and pop them in.

The media could not be loaded.  The video attached is of the batteries not working two months after they were delivered.Out of the box brand new, the batteries seemed to work fine. I put them on the charger, the lights were red when charging, and green when fully charged. Great (so I thought). I needed to use them in pairs for my smart lock so I put the first pair of the 4 batteries in my smart lock. It took about 2 1/2 weeks for the first pair to die (which is about 2 weeks quicker than the Duracell batteries of the same kind I was buying) so I put them on the charger, but no lights. I was thinking that even if these didn't work but the other pair did, I'd be OK with that. I put the 2nd pair in my smart lock, they lasted about 2 1/2 weeks, and I put them on the charger. NO LIGHTS! NO CHARGING! I left them on the charger just in case they were charging anyway without the indicator lights, and shortly after putting them in my smart lock, the smart lock stated that the batteries were less than 20% and needed to be changed.Fortunately, chatting with an Amazon Associate resulted in me being able to return this item since it was after the return window, but for a product like rechargeable batteries, it takes more than a month to know whether they work properly or not. I'm happy with Amazon for allowing me to return it (I think that's easily the right thing to do) but DO NOT PURCHASE THIS ITEM. It's not worth the hassle.

Great batteries. Work great in weapon lights. Flashlights etc

Great batteries and the charger is adjustable so I can charge other battery types.

Awesome product if you use this type of battery a lot.
