elxjar (2-Pack) TL-5902/T 3.6V 1/2AA Lithium Thionyl Chloride Battery Replacement for Tadiran TL-5902/T T Terminal - iXtra Series, 1.2Ah Capacity

Very Easy to Solder Into Place

I use these in the wireless security systems we install, and they've been a solid replacement for the more expensive brand-name batteries. They fit perfectly, and I haven't had any issues with compatibility. So far, the performance has been consistent, even in our outdoor installations that face some pretty extreme temperatures. Installation is straightforward, and the price is right, especially when buying in bulk. I always appreciate finding reliable parts that don't break the bank.

Fit: I made the same mistake twice. I implore any prospective buyers to double check the size before ordering. This is not a traditionally sized battery. Value for money: As far as I am aware, this is a great price for a lithium ion battery like this! Quality: These batteries seem to be of high quality. Of course, I couldn't end up actually testing them out, but they came in secure packaging and it certainly looks like a quality product.
