(2) Tekcell SB-AA02 14250 1/2 LITHIUM BATTERIES FOR ADT

Other brands have lasted 10-11 years in this application, but these I just purchased in May are already dead in October. Their life was literally 20x shorter than other brands! One was installed in a sensor, the other still in the package, now both dead after just a few months, for a supposed 10 year battery.

These are exactly the same batteries as ADT use in their wireless security system and of course they charge much more if they are the ones replacing them! The take over a week to arrive but well worth waiting for as the price is great.

Worked as expected

I could only find this battery on Amazon. It arrived early and the sensor was back in working order.

I did not know 1/2 AA existed until I needed one. This one fit as expected. Came in a two pack. Suspect the second one will be dead about the time I need it. But was the better deal for the price at my time of purchase.

I ordered these batteries they arrived today around Noon. I inserted them and the alert said the low battery notification ended then 2 hours later I get notification battery is low. Batteries usually last years this one didn't make it a couple hours. The thing is these batteries are hard to find and I waited a couple days with this constant BEEPING now I have to return these and Scott around AGAIN for a good battery!!!!! True waste of time no value with these batteries as I've wasted time and gas to return them and burning more time and gas to go to batteries plus across town at least I know theirs will work and price isn't that much different

I haven't had it for long, but so far is doing what it is supposed to do.

Very weak battery, didn't last more than an hour in a laser.
