MVMOD CR123A 3V Lithium Battery 4 Pack, 800mAh Rechargeable Batteries for Arlo Wireless Security Cameras VMC3030 VMK3200 VMS3330 3530, CR123A Battery with Type-C Cable for Flashlight Polaroid MicrophoneThe MVMOD batteries are lightweight, recharge quickly, and last a good while during use. I have had them for some months, and note no decay, leakage, swelling, or distortion secondary to a few dozen charge/discharge cycles.At about $30 when I got them, and a coupon on offer now, these batteries not only serve well but offer an excellent value for money.

Really like being able to charge with a USB C cable. The Y connectors come in handy.The cells are rated at 800 mah but this doesn't give a C rating. At 330 ma. they offer ~600mah. This is in a Cree flashlight which lasted almost 2 hrs before the battery was in need of recharging. They would give the 800mah rating if operated at 150mah or less.The reason of 4 stars is due to one cell being defective. On Initial charging, the cell got hot and did not hold the charge. As with all lithium batteries, always keep an eye on them during charging.Amazon done a replacement with no problem, THANKS AMAZON!Overall I am pleased with the batteries.

The batteries are just a teeny bit wider than a standard battery in order to accommodate the charging port. I am using these in a flashlight, and I need to shake the flashlight vigorously to get the batteries to stick out enough to grasp them and pull them out in order to charge them. If your use case doesn't require inserting them vertically, you likely won't have an issue. The batteries have two tiny red LEDs on the positive end that show charging and turn green when charged. I don't know how long they take to charge from zero charge as I've not had them completely discharge yet. Would give 5 stars if they were the same width and length as a standard battery.

Juego de 4 baterías recargables para cámaras de seguridad inalámbricas, o para linternas, se recargan con cable tipo C, duran varios días la recarga, buena opción.

These batteries charged the first time I used them, only one battery had to be reconnected to charge successfully. Third time I go to charge them 2 won’t charge no matter the charger or how many times I reset the connection. Just passed the 30 day return time.

I too, used these to put into training TASER products that typically take 2 CR123A batteries. I can't even begin to express how appreciative I am of not having to keep purchasing batteries for the trainers. The last thing you want with a TASER is weak batteries, these rechargeables allow you to change the batteries as often as you like to ensure your conductive electrical weapon is "topped off". Great technology!
