OPTIMA® BLUETOP® 34M Ultra high-performance SPIRALCELL TECHNOLOGY® AGM (absorbent glass mat) starting battery for marine and RV. BLUETOP® has ultimate cranking power in a maintenance-free package. Lower internal resistance provides more efficient power output and faster recharges. If you are looking for a group 24 or 34 battery for boat or RV starting only, this is the one for you.
If you also have live wells, GPS, pumps, etc., running on the starting circuit of your boat, or if you are looking for house batteries for your RV, please see one of the BLUETOP® dual purpose deep-cycle/starting batteries (D34M, D27M or D31M).
The OPTIMA® model number for this battery is 34M. If you are replacing an OPTIMA® battery you already have, this model is the same as batteries marked 8006-006, 9006-006, 27935, 34M-1050, BLUES34, SC34M, BLUES34, or N9934MBLUE.
