Going to be putting my car in garge for a couple of weeks so I bought a battery tender, my question is by keeping my main battery charged will the backup batteries in my alarm keep their charge to?

here's the model I bought http://www.amazon.com/Battery-Tender.../dp/B00068XCQU

Thanks for the help...

 

If you have a battery tender on the main battery then yes your back up battery would also stay charged.

 

Thanks for the help.
