Battery Be Recharged If Low On Acid

10' cables are the way to go. Plenty of length to get to where you need to be.

The Sony battery lasts longer than the off brand batteries. It can be recharged more times.

5 stars! Stable and very easy to adjust level with slider on.

These headphones work great with a pretty long battery life before it needs to be recharged!

This is the best and brightest pen flashlight that I've ever owned and the battery has long live before needing to be recharged.

Being able to use it wherever and whenever with the battery is the best thing ever. It also lasts quite a while/lots of shot if not using it at full power. Have had it 2 months and only recharged it once so far. It's a powerful beast of a light and this combo is PERFECT.

Received the battery pack. Since there was one comment that stated the plug on the one he received was recessed and did not work correctly, I examined the plug. Did not find the problem. Put in 4 recharged batteries in the pack (could have put 8 but only had 4 recharged.) Put in the 4 required in my flash. Checked the flash settings and had to change one to flash and external. Put the flash on the camera, plugged in the battery pack and mounted the pack to the base of my 5d battery pack. Started shooting. Found mounting this to the camera was a bit cumbersome as I shot. Recycle was as listed (1 sec +) and shot about 50 shots in fairly rapid succession. No failures. Worked as advertised. Unmounted it from the camera and put it my pocket. Then shot in manual mode, AV mode TV mode and auto. No problems. Would recommend this to anyone.

a great battery pack for camping and emergency use. It can be recharged from a 7 watt goalzero solar panel. i keep two rcr123a batteries and two lights in the case

I was asked by Coast to review the ZX AA battery as a field tester. Coast sent me a package that contained 4 AA batteries as well as a charger. The instructions advised to charge the batteries prior to using. The charger is capable of charging 1-4 batteries at a time. The batteries have a USB-C charging slot so it was easy to connect the charger and start that process. The power source end of the charger cleverly is able to be plugged into a USB-A or USB-C adapter. The batteries were fully "recharged" in about 20 minutes. There is an indicator light on each battery for the status of the charging process. I tested 2 batteries in one of my many Coast flashlights. The batteries provided power for just over 4 hours before needing to be recharged. There was no change in brightness of light while the flashlight was on. The recharging process took about 30 minutes. If you are looking for AA rechargeable batteries, these are a nice choice!

I've only used it once, as a backup for the original battery that came with the camera. It worked well, held its charge, and recharged quickly.
