Sorry. :blush: This is the one I have. It is the 34M Starting Marine Battery.
Marine/RV Battery
OPTIMA Blue Top batteries, featuring SPIRALCELL TECHNOLOGY, are designed for all of your marine and RV, starting and deep cycle needs.
Vibration Resistant
The constant vibration and jarring from waves can be deadly for traditional marine batteries. The tightly wound construction in OPTIMA batteries minimizes plate movement and subsequent damage caused by harsh conditions - extending battery life.
Constant Performance Quality
OPTIMA Blue Top batteries provide constant performance quality as they are discharging. Even as energy is being drained, your equipment will perform at the same level as when the battery was fully charged. Meaning, you will not hear or feel your equipment slow down or strain for power.
Nonspillable
Because of its completely sealed case, OPTIMA Blue Top batteries are extremely safe. Acid can't leak or spill, making them clean, user-friendly and environmentally sound. In addition, the maintenance free sealed case design eliminates the need to add water or clean terminals.
Retains Charge / Recharges Faster
Marine batteries sometimes sit for months at a time and lose their charge. But the OPTIMA Blue Top battery has such a low rate of self-discharge, that it can go unused for up to one year without recharging, if it's kept at room temperature or below. And because of its low internal resistance, it recharges faster, getting you back on the water quickly.
Mounts in Almost Any Position
OPTIMA Blue Top batteries are leak proof, so they can be mounted anyplace inside boats or RVs, in almost any position.
