I know that this subject has been beat to death but I cant seem to get a straight answer from anyone

I am looking for the best battery for powering my sound system for long periods of time.

The Yellow and Blue top are the same battery internally. The difference between the two is the blue top has the wing nut battery connections in addition to the slug type pole connectors.

Just make sure you get either one with the "light grey" case instead of the dark grey.

Light grey = deep cycle
Dary grey = starting

Been using the blue top OPTIMA for my stereo - works great - have not drained it flat yet, & thats with 2 large amps going for extended periods of time - well worth it in my book

Will a Optima D31M fit a battery holder that comes on a stock Fountain (32 ft)?
