CR2 Rechargeabe Battery

On first try, the battery charger was delivered without the four rechargeable batteries! I then had to return the partial delivery and wait for a replacement order to be shipped. After an extra week, the second order arrived and all items were in the package and in fine working order. Yeah! Now I am happy.

Good for the earth and convenient

I’ve had a line 6 G10 relay laying around for a couple years, which was dead as a doornail. Then I saw a YouTube video that said it was probably a worn out lithium rechargeable battery. Only problem is the people on the Internet couldn’t find the right size battery, and had to do some modifications which was a pain in the ass. But these batteries are perfect size. No modification needed and they work great. Plus you get a couple spares in case the thing goes dead again in the future. But now my line 6 G10 Relay is working perfectly again.

There are many pistol lights in the market.. my choice was a Crimson Trace CMR-209.. this pistol lights uses a CR2 Battery is not you traditional CR123.. but close.. a bit smaller. The price for this batteries is not bad, but I like to have spare ones so this little package with charger and 4 included batteries just might do the job …will see how they hold up with use and charging cycles..so far I am happy 👍

These are junk. Buy real brands. I tested these out and charged all of them completely. I then installed them, each one at a time, to see how long they would last when the item was off. Yes, off. They would die in right about 8 hours. Yes, they drained out that fast when not in use, just installed.

Bought for my range finder and it works very well. Can't speak on longevity yet but they last a long time so far. For the price, I'm happy and would recommend for what I use them for.

The item description states that it is ideal for the "SmartThings water sensor" but it is a very snug fit compared to non-rechargeable batteries. The battery is just slightly taller (maybe wider?) than a normal CR2 battery and the way the battery compartment is designed on the SmartThings water sensor, it has almost no clearance. You have to push the battery in with a bit of force. Removing it will probably require a flat head screwdriver. It's not too bad so I will keep these.

I use this for my August 4th Gen Smartlock. It will save me a good bit of money I can see VS buying new batteries every 6 months. Came almost fully charged, but I topped it off and installed and it's been working well for months. Time will tell if it lasts as long as single charge, but I'm pleased so far.
