This a great forum and have been reading the past couple weeks.

Ok fellas Just bought an 09 LSV and looked thru all the dual batter/perko threads and couldnt find an answer to my question. Currently have a single battery and going to upgrade to a dual battery with a perko switch.

My question, do i need to buy 2 fresh batteries? Or the 2yr battery will be fine and buy the new battery for backup? I saw the thread talking about if youre running a new battery in parallel with an older battery the risk of shortening the battery life of both.

Anybody pickup a new battery and put the perko on, or went and bought 2 new batteries (expensive)
