Re: Problems with Optima Warranty.

The chassis batteries on my U295 are three Optimas connected in parallel. Shortly after I bought the coach (used), I noticed the batteries were unable to hold a charge for long and pretty much needed the boost switch for reliable starting. I disconnected the batteries, and discovered one of the three had a shorted cell, dragging down the other two. I ran for a while with just the two good batteries, then replaced the failed one. You might have just one bad battery and two reasonable good ones.
