Reply To: Optima Red Top Concerns

[Craig Castillo]

Since the Optima red top is a standard AGM battery it does not tolerate being flattened or run very low.

They also do not tolerate being overcharged for extended periods.

I first installed an Optima red top in my ’29 back in 2006.

It was still working fine when I replaced it 7 years later but given its age I replaced it anyway.

I now keep the old one as a spare and it still holds a charge just fine and starts the occasional project car here and there.
