## Description

Optima Battery D34M Blue Top Battery

Review: Early death and no warranty - I bought 3 of these BlueTop batteries, as starter batteries for my sailboat (24V for engine, 12V for generator). One of the batteries started degrading after about a year and wouldn't keep a charge above 12.3V (when the other 2 are happily staying at 12.9V). After trying to recondition it with a higher charge profile/mode, the battery's health didn't improve and had to be disposed of. I'm getting the runaround from desertcart regarding the warranty. Optima has a 2 years warranty on the BluetTop batteries. Doxa-Worldwide, the seller on desertcart will not honour the warranty either. So now I only have Optima, the manufacturer, left to honour the warranty.
Review: Don't buy - I bought three of these batteries. The first, bought in 2011 lasted 6 years. The second Optima blue top, bought in 2017 lasted barely 2 years. The third Optima blue top didn't even last 2 years. They obviously lost a customer.
