Optima Bluetop Marine 900cca 75ah 24 month private use / 12 month commercial warranty

The Optima D31M is a 12V 900CCA, 75Ah (Amp-Hour) Dual purpose battery (Starting & Deep Cycle). The D31M Optima spiral cell design with the plates wound tightly around a central core gives exceptional vibration resistance (15 times more than most batteries)

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 4x4 bush trips for camp lighting, but then ended up using them for all the vehicle starting as their normal starting batteries failed in turn.

Leak-proof, spill-proof and almost bomb-proof, they are completely maintenance free and can be installed at an angle if required and under-bonnet is fine too.
