bad optima battery...any other negative experiences?

[Mark R]

I've personally used and sold a lot of them over the years.  What
seems to fail them is if they sit for a long period of time and drain
down.  They will bounce back, but do it again and they're toast. 
Otherwise, I've had nothing but good luck with them and even have made
some custom mounts (especially for A4/S4) to mount them in Audis after
seeing what spilled battery acid out of the stock battery does.  I've
only seen this in cars which see track time, FWIW.  With the Optima,
no more fears of spilled acid.  Also, for high-end stereos, the lower
internal resistance means less load on the charging system, so I've
used a lot of them there.

Just like any battery, if you maintain it, they last a long time. 
Personally, I had one last 7 years on a daily driver.  I've also had
one fail in a customers car that basically sat 4+ months straight. 
That battery lasted 2  of these cycles and was dead.  I got it
replaced under warantee and sold him a battery charger to use once or
twice per month.  That was about 3 years ago.
