123A Rechargeable Batteries, 20-Pack 3.7V 123A Batteries Rechargeable and CR123A Charger for Arlo Arlo VMC3030 VMK3200 VMS3330 3430 3530 Cameras, Alarm System, Flashlight

We have five Arlo cameras at our house. The cost of batteries was getting very expensive as they were not holding a charge for very long so I saw an ad for these rechargeable batteries and I thought I would give them a try and save a lot of money getting these then buying regular batteries And you don’t have to change them as often. Wish I had gotten the rechargeable ones long time ago.

Purchased in February this year and the life of theses suck. Most of the batteries will not hold a charge after 1 use. I recommend you buy elsewhere.

We bought these as spares, so just because one battery won't hold a charge didn't affect us a lot. I'd order from this seller again. But it this problem reoccurs, I will request they send me a replacement for any that don't hold a charge.

Rechargeable batteries Save money over standard alkaline or lithium batteries. Seems to last about as long as non rechargeable batteries but time will tell.

Included in the box is an easy to use charger with 20 rechargeable CR123A NiMH batteries. The charger also includes the USB cable and power supply adapter, so everything needed to get started is included. The charger can be plugged into any USB-A power port with a capacity for at least 2 amps. The 20 batteries are packaged as five packs of four batteries each. The batteries should be charged the first time. Open circuit voltage out of the box is typically 3.9 volts. After charging this rises to 4.2 volts, but under load will decrease to the nominal 3.7 rated voltage. The charger can charge up to 8 batteries at a time, and any number of batteries can be charged at once, from 1 to 8. When the charger is first powered up, all of the LEDs will be steady green. When a depleted battery is placed in the slot, the LED turns steady red. When charging is complete, the LED turns green again. Initial charging took about an hour. The batteries are vented in the positive end caps, so there is no danger of bursting or explosion from gas buildup. These are NiMH batteries so they are suitable for low to moderate drain application. For heavier duty applications such as devices with a motor drive, lithium versions of these batteries are recommended. Just a safety note - use the proper charger for the particular size, voltage and chemistry of batteries. One time use batteries cannot be used with this charger. This is a great value pack for commercial, business or home used.

I have several Arlo cameras at home that still use these batteries. I have been using rechargeable batteries for a few years as well, and they are now not lasting quite as long. Plus, I only had the capability to charge 1 set of 4 batteries at a time. This set comes with 20 rechargeable batteries and a charger that can do 2 sets or 8 batteries at a time. Also, the charger uses a standard micro USB cable. Although I wish it was Type C, this will still help a lot as I can charge from my own cables. The quality of the charger seems ok only. It will light up green when the battery is done charging or even when no batteries are in the compartment. It is very small and not much bigger than my 4 compartment charger. The batteries also charge up quickly. I'm sure they come with some charge but my batteries were done charging in about 1 hour. I assume around 2 to 2.5 hours for a fully drained battery. As for the batteries, they fit fine in my Arlo cameras. So far, no issues with them and they are draining down slower than my other batteries. Since this comes with so many batteries, I now will have spares ready when I need to change batteries. Lastly. It's hard to beat the price of these. They aren't much more expensive per battery than regular CR123 batteries. Just using these a few times will make them more cost effective.

Got these for rechargable batteries for CLOUD and SureFire lights. Some of the batteries work great. Some don't. I can't recommend for life saving or duty applications but for general purpose use they may work out great for you.

These batteries do not hold a charge well. A standard Panasonic battery will last in a window sensor about 2-3 months. These hardly lasted a week. I have returned them. I do not recommend.
