OPTIMA® BLUETOP® D34M Ultra high-performance SPIRALCELL TECHNOLOGY® AGM (absorbent glass mat) dual-purpose battery for marine and RV. BLUETOP® has three times the cycling capability (rechargeability) with ultimate cranking power for your boat or RV in a maintenance-free package. Perfect for multiple high-demand accessories and trolling motors with 15 times the vibration resistance and lighter weight. Lower internal resistance provides more efficient power output and faster recharges.

If you are looking for a deep-cycle group 24 or 34 battery for boat or RV, this is the one for you.

The OPTIMA® model number for this battery is D34M. If you are replacing an OPTIMA® battery you already have, this model is the same as batteries marked 8016-103, 9016-103, 27934, D34M-950, BLUED34, 12854, SC34DM, or N99D34MBLUE.
