CR123A Lithium Batteries, DULEX CR123A Rechargeable Batteries, 4-Pack 700mAH 3.7V ICR17335 Battery and Charger for Arlo VMC3030 VMK3200 VMS3130/3230C/3430/3530 Security Cameras, Alarm System

Overall this is a well designed and thought out product. The charger has an input for your own usb (you may have a long cord that suits you) as well as a built in usb that wraps around the charger storage. I have tried both and they both work perfectly. It also charges four batteries at a time which makes it great for Arlo, my reason for buying it.The one downside to the charger is that two of the slots wouldnt make good contact with the batteries and charge them. It was easy enough to bend them and get them to work but its a clear oversight in manufacturing.The batteries themselves are in my ARLO camera and working well. They have lasted several weeks of heavy use (my front door) without needing to be recharged.Over all this is agreat addition to my ARLO and i can recommend it to others.

I absolutely love the charger and the batteries. They were delivered a few days earlier than expected, which was wonderful. I plugged them in the charger just before going to bed, and they were ready first thing in the morning. I love how sleek the charger is, because I need compact items for the purpose I need them for. This is an absolute must for anyone that uses CR123A batteries regularly.

I waited to write this review to try and give the batteries and charger some real life experience. They both performed very well. I was happy with the ease of use of the charger and compact size. Took these on a recent long drive trip up and down the east coast and used the batteries in a top rated flashlight. The batteries outlasted my patience, as I was trying to run them down, and I changed them out before they were fully discharged (about 10 hours at medium flashlight intensity). They fully recharged in about 20 minutes. would have given value for the money a 5 star rating, but want to see how long these will last.

I bought these 6 months ago and they work very well. We have 4 Arlo cameras which altogether use a total of 16 batteries (4 each). I also bought 8 more so I can charge for two cameras at a time and have the batteries ready to go without having camera down time. It takes about 1.5 hours to charge 4 batteries in the Dulex chargers (bought 2). I do store the extra 8 batteries in both chargers BUT the charger is not plugged in, to avoid overheating and exploding. I just pull out the chargers and plug them in whenever a camera is low on battery. This way there are always 8 batteries ready to go in about 1.5 hours. Once charged the batteries have lasted 3-4 months. Good quality. Delivered brand new and in great condition. Reliable, dependable vendor.

This is very easy to use. Did the initial change which took about 1 hour and put the batteries in a flashlight. Everything worked great. I used this charger with a different battery without issue. Very pleased with my purchase.

Can't rate the battery life. Only had them for less than a week. Price for a 4-pack and charger was good. Delivery was in 2 days from AMAZON. Use was easy af. Put in charger, wait til red lights turn green, put in device. Comes with a built in USB cord, but also has a built in micro port and new c-style port. Handy. Will update battery life later. But rechargeable Li-On's usually do good. Got for a tactical flashlight.

The charger is well-made and the batteries seem top shelf. I'm curious to see how long they last relative to standard Surefire batteries. I will update this review once I get an idea of lifespan. Assuming all goes well, I will be purchasing more batteries. I currently purchase this package as a test run.

Light powered by two batteries is maybe not quite as bright as with other non-rechargeable batteries, but otherwise works as expected.The multiple inputs on the charger is nice, as well. Makes running it from solar / vehicle much simpler.
