CR123A Rechargeable Batteries 8-Pack, 3.7V 800mAH 123A Batteries Rechargeable for Arlo VMC3030 VMK3200 VMS3130 3230C 3430 3530 Wireless Security Cameras, Flashlight

I use these with my Arlo security cameras and they recharge without any problems. Cold weather does cut battery life but thats why I buy rechargeables.

Great batteries work great for me even after months of use and daily recharging.

I'm just now using the batteries and will update my review based on the performance. My battery charger was detecting these as Li-ion not NiMH so I began investigating. It’s highly unlikely that these batteries are NiMH and here’s why: - Voltage Mismatch: NiMH batteries have a nominal voltage of 1.2V per cell, far below the 3.7V specification of these CR123A batteries. Even multiple NiMH cells inside the casing would struggle to achieve the stated 3.7V. I don't want to cut open the casing to find out myself. - Energy Density: NiMH batteries typically have lower energy density compared to lithium-ion batteries, which means these would not be able to deliver the capacity (800mAh) and energy rating (2.59Wh) in the compact CR123A form factor. - Typical Usage: CR123A batteries are often used in high-drain devices like cameras, flashlights, and security systems, where lithium-ion chemistry is preferred due to its high energy density, stable voltage, and ability to handle high-drain applications. NiMH batteries are more common in applications like AA/AAA rechargeable batteries. Based on these points, it’s almost certain these CR123A batteries are not NiMH and are instead lithium-ion.

Purchased these items for my flashlight and they save a lot of money

I use these batteries on my Rayovac flashlight as a security guard overnight. I rely on the rechargeable ones to get me through a shift at work. These have worked very well.

Batteries arrived on time and showing 4.1v

The product claim is the battery are good for 600 recharges and they are for Arlo cameras. They do work in Arlo cameras but I get a couple recharges on a battery 3-6 months use and they will not recharge. Every time I need to change batteries there will be at least one of the four batteries show fault on the charger. I need to find another brand. Aka I did purchase two new Arlo cameras with built in rechargeable batteries and so far they have been outstanding. They last for months, recharge in a couple hours and work.

Have several security cameras that use these batteries. I have used these batteries for about a year and have had no issues with charging them. They also last quite a while before needing to be recharged.
