A really fine battery supply store. Very wide selection of specialty batteries.
I have only used them for motorcycle batteries, so my experience is limited. But they are fairly knowledgeable and friendly.
Only knock so far: I've been waiting two weeks for them to contact me on the status of the battery I have been waiting for. No one from the store has contacted me, which leads me to believe that they have not received it yet.
Long story short...call them or stop on because they don't seem to follow up.
To me, this is not acceptable, but hey, it's Las Vegas (Eastside).
