The Optima D31M is an extremely tough battery, with huge cranking amps for its size. This high starting power, combined with cycling capability (in Yellow Top and some Blue Top’s) makes an Optima an excellent choice for many applications. Fast recharging too with its Absorbed Glass Mat (AGM) design. Some of our customers after fitting Optima’s in their boat could not believe how quickly they recharged on a short trip (only 35 minutes from flat to fully charged at 100Amps for the larger Yellow Top’s). Other customers have taken Optima batteries for tough 4×4 bush trips for camp lighting, but then ended up using them for all the vehicle starting as their normal starting batteries failed in turn.

Key Benefits:

• Both dual-purpose and starting applications available
• Up to 3x more recharges than other marine batteries
• More than 15 times the vibration resistance
• Spill-proof
• Mountable in virtually any position
• Maintenance-free
• Optimal starting power (dual purpose and starting applications available)
• Works well as a boat battery or Mobile Home battery
