I have a question for people that use battery tenders--how long do your batterys last?
When I passed the tent selling batterys and tenders I was told a tender would double my battery life.
My reply was really--it will make my battery last 30 years ? (at the time the optima was 15 years old)
---Oh no, it will double it to 5-7 years
So with regular batterys I got 7-9 years, the optima lasted 16, a 10 year old Mercedes battery that I cut in 1/2 to make it 6V lasted 4 more. I do have a high charge rate(14amps), drive a lot at night, have halogen bulbs, don't do anything even parked for 6 months ---so what do you think, will a battery tender double my battery life, make the car faster, start quicker, more reliable?
