I've got two 6 volt Exide Extra 135 batteries that are dated Oct. 2008 as my class A house batteries. Couple of questions: Are they about out of life and should be replaced? They are apparently a h...

Assuming they are physically ok, then test them and see if they hold a charge.
Charge them up, measure the voltage, then put a small load on them (12v bulb),
measure the voltage 12 hours later - it should not have lost a lot of voltage.
Now leave it with no load for say 1 week; It should show the approx same voltage.
If it loses voltage (say 0.5V) over the week - then the battery is on its way out.
good batteries should not loose voltage over a 1 week period.
