My XS Power D2400, XP3000 and my Yellow Top is now 6 years old today.

They sit on the CTEK MULTI US 7002 Battery charger daily every night in the garage when car is not in use.

Who here thinks I should wait another year before replacing all 3 at once?

XS Power seems to say the average life span on those are about 5-6 years of daily beating

If they are still getting the job done there is no need to replace them, ive had batteries last 10 years, its all depends on how you take care of them and what kind of envrionment you live in.

My first real system had a set of dekkas that were 10 years old when I bought them.

They lasted me a good 3 more years too
