I've noticed a few 2012 S10 owners are having to replace their original battery. I was going to replace mine at next service just to be on the safe side, but then I bought a little voltage indicator that warns of a battery going bad. However, I was at TSC today and saw a lithium jump starter battery on sale for 54 bucks. Several BMW's at the last rally did not start the next morning and a jumper would have been handy. With all the demand now placed on our motorcycle batteries, I started carrying an extra Battery Tender on trips since it takes so little room. Thinking of switching it out to a lithium jumper pack. Anyone else have any experience with this ?
