  • 100-minute reserve capacity at 25 amps
  • 50 Ah C20 capacity for extended performance
  • 15 times more vibration resistant than traditional flooded batteries
  • Up to 3 times longer service life than standard marine batteries
  • Completely sealed and spill-proof design
  • Mountable in virtually any position
  • Maintenance-free operation—no water additions required
  • Faster recharge capabilities than conventional batteries
  • Low self-discharge rate allows storage up to one year without recharging

Ideal Applications:

Perfect for boats with high-demand starting requirements, RVs, and marine vessels exposed to constant vibration and harsh conditions. The Group 34M case size provides a reliable fit for applications requiring robust starting power. Includes a removable carrying strap for convenient handling.

This is a starting battery designed for engine cranking applications. For dual-purpose starting and deep-cycle needs, consider the Optima D34M model.
