Xeno Energy XL-050F 1/2 AA 3.6V Lithium Battery

I needed this battery for my security system. The battery was the perfect fit and reasonably price. This is my second time purchasing one of these batteries I like the quality of this product. Will buy again when another one on my security door alarms need replacing.

Needed this battery and was impossible to find in store. Easily found it on amazon and it was priced cheap. Not sure if it’s advertised but it comes with an extra one! Would buy again.

Cheaper then any local store odd size battery fast shipping

The battery arrived quickly and works well. From a product standpoint, the quality and value are outstanding. However, this has to be the single-most overpacked item I have ever received from Amazon! The seller - MYBATTERYSUPPLIER - decided to put a battery half the size of a AA in a box big enough to hold a toaster, along with excessive packing material.Yes, my order arrived quickly and in one piece, but wouldn't a bubble envelope had been enough? Or a small padded mailer? As it stands, while I am happy with the item and it arrived fast, I feel guilty knowing that so much packaging waste was generated from such a small item. Seriously, a few hundred of those batteries could have fit in that box. Good intentions all around, but because of the excessive packaging, I will not be buying from this seller again.

These batteries work just as well as the big name brands. Save some money with this brand of batteries. They last a long time and the price is right.

Purchased this battery on Amazon because the price for the same item at a store, if i could even find one in store, was ridiculous. This battery fit well, and had lasted a long time.

Sweet, works just like a battery should.

Item was not as described. It was not the item # as it claimed. This battery kept popping out of my alarm system, it would NOT fit.
