Battery Tender Question

[drewsss]

Did a search and couldn't find an answer to this one...

I have two batteries in parallel. First one is the stock 12V lead acid battery, and the second is a 12V dry cell (Stinger SPV35, 525a) mounted in the back to drive two amps, two subwoofers, etc.

Also had a breaker installed to separate the circuits when it's parked for long periods of time, so they won't draw on each other.

Question is: can I use my Battery Tender to charge both 12V batteries at once, knowing that one is lead acid and the other is a dry cell?

A poser question for sure, so maybe D6666 will swoop in with some...comments. But I welcome useful advice from anyone else.

Thanks,
Drew
