Engineered for maximum energy density, this battery has 315 Amp Hours of capacity in a waterproof Group 31 battery case, the same size as a typical 100 Amp Hour battery. Plus, up to 1,000 cold cranking amps of emergency engine jump-starting power, making this battery the ultimate solution for boats, RVs, or any vehicle where you need a house battery that can jump start your engine.

Built with a reinforced and ruggedized marine spec plastic case, an expected lifespan of 5,000 charge cycles, and an 11-year warranty, this is a battery built to last. A small LiFePO4 optimized charger is included.

Self-heating
When charging the battery in temperatures below 0°C/32°F the internal heating element will warm the cells, letting you charge even in freezing weather.

Warranty
Best in Class 11 Year Warranty.

Storage Capacity
315 Ampere hours (Ah). This is much more energy than is usually found in a battery this size.

Cold Cranking Amps
1,000 CCA is adequate for emergency jump-starting of most boat and large vehicle engines

Energy
3780 Wh

Voltage
12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems)

Size
15.06"L x 7.24"W x 10"H (383mm x 184mm x 254mm) Height is to the top of the terminals. **See Group Size notes for battery tray and battery box sizing**

Group Size 31
The DL+ 12v 315Ah battery is a Group 31 sized battery. The bottom footprint dimensions are 13.31″L x 7.24″W x 10″H (338mm × 184mm × 254mm) and will fit in most Group 31 sized battery trays. The top of the DL+ 12v 315 is a little wider, incorporating handles. The dimensions at the top are 15.06″L x 7.24″W x 10″H (383mm x 184mm x 254mm) which means some Group 31 size battery boxes may not be compatible.

Weight
65 lbs (29.5Kg)

Safety
All DL batteries are UN38 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Meets all US & International regulations for air, ground, train, & marine transport.

Terminals and Posts
M8 bolt size included. (Max torque 15 ft. lbs.) (Max 5 ft. lbs. on terminal post adapters)

Lifespan/Lifecycles
Up to 80% capacity for 4,000 cycles in recommended conditions, 70% capacity at 5,000 recharge cycles. Half-life (50% capacity) of 6,000 - 7,000 re-charge cycles (Typical SLA has 500 cycles). Backed up by an 11 year warranty.

Discharge
200A max continuous, 300A max 10-second pulse, 1,000A max 2-sec CCA pulse. LiFePO4 chemistry has a flat voltage curve, meaning this battery will maintain a voltage of >12V for the full discharge cycle in most applications.

Charge
Up to 200 A standard charge, 300A max charge current for up to 60 sec. Included is a simple LiFePO4 compatible charger. Internal even-heat technology allows for charging below 0°C/32°.
