6V Door Lock Battery for Saflok A28110 Replaces HTL11 Alkaline

I ordered this after my locksmith wanted to charge me $20 to change the battery in. My Townsteel electronic door lock, sorry not sure what model it is. This one was a direct replacement at less than half the cost. No problems so far, actually it seems to. Have lasted longer than the first one I bought from him as well.

Purchased from BIAF (Batteries In A Flash). Battery was shipped 3/7/2017, and today is April 28, 2017 and the battery is already dying! Didn't even get two months of use.

Great!
