Thread: Optima Yellowtop Failure

Was wondering why my deep cycle battery was misbehaving over the last couple of weeks. Had a look at the voltage this morning - 8 volts, better charge it up...
The negative terminal has corroded right through.



It's about 6 years old so I guess I can't complain too much but it lives under the plastic cover on the D3 so it isn't mechanical failure.

Hmm, I had an Optima yellow Top die ( well be very sick) at 3 years of age.
I discovered that it was leaking out of the negative terminal .
Seems eerily the same.

AFAIK the alternator was charging correctly usually at 13.9 when warm.

I must admit this was 15 years ago, and I just now have come back for more with a Blue top as my starting battery.
