WEGWANG 3.7V 123 Lithium Rechargeable Batteries 4 Pack and Arlo Battery Charger,800mAh Li-ion Battery Compatible with Arlo Wireless Security Camera VMC3030 VMS3130 VMS3330 VMS3430 VMK3200

Batteries arrived quickly. They do a good job in a powerful flashlight and last for a week or two before they need to be recharged. After a year or so they lose capacity and start needing to be recharged every day or so. Worth the money

They are good,

I had bought these for my August Smart door lock. These are better alternatives than buying the non rechargeable ones every two months. These came about month and a half initially. Later they deteriorated quickly down to 3 weeks. I contacted the customer service and they were kind to send another complete set without any cost. Overall I just wish the price would be lower based on their performance.

Got them for my laser light. They’re working great.

I bought this battery in January 2021. Initially worked well, but will no longer accept a charge after only 3 cycles, in April 2021. Update, 5/9/21: Placing the battery on the charger did not trigger the yellow light ("Charging") or green light ("Charged"). However, the green light appeared after several days, and the battery appears charged. I changed the rating from 1 to 3 stars today.

This thing has been amazing and has kept us from having to buy more batteries for the ARLO security camera. The batteries seem to stay charged for a long time and it's very easy to use. Def worth the money.

Did not work more than 5 minutes. I used in a flash light and my flashlight stopped working after putting these batteries in. Just spend the extra money on name brand. These are not worth it.
