11 Year Warranty

World beating, best in class, eleven year manufacturer defect warranty.

Storage Capacity

135 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 135 amp hours. DL LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.

Voltage

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

Engine Starting Power

Lithium battery equivalent to 1,000 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive and other applications. Marine Outboards: Please refer to your manufacturer recommendations.

Size

9.5”L x 6.9” W x 7.75” H (242.5mm x 176mm x 197 mm) Group 24 equivalent.

Group Size 24

Group 24 compatible physical dimensions & 24F terminal orientation. Cranking power (CCA rating) & usable deep cycle capacity is much higher than a lead-acid battery of the same group size.

Energy

1620 Watt-hours (Wh).

Terminals

F12 terminals (posts that screw in) with M8 size bolts. Includes a terminal adapter kit with automotive & marine posts that screw into the M8 bolt terminal, and M8 brass terminal bolts. Easy to adapt to different connection needs. (Max torque 15 ft. lbs.) (Max 5 ft. lbs. on terminal post adapters).

Weight

27.2 lbs (12.3 Kg). 65% lighter than a SLA or lead battery. 1/2 the weight of a normal car battery.

Lifecycles (Battery Lifespan)

Up to 80% capacity for 2,500 cycles in recommended conditions. The typical automotive SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries.

Operating Temperature

Ideal for rugged & harsh environments. Much better than SLA or other lithium batteries. -20'F min, +150'F max optimal operating temps (battery performs well down to -20'F). Internal even-heat technology allows for charging below 32'F. BMS high temp cut off at 167'F / 75'C.

Discharge

270A max continuous discharge, 1000A max 2 second pulse, 900A max 5 sec pulse. The flat discharge voltage curve provides a 75% bigger capacity than a 135Ah SLA battery with the same CCA rating.

Charge

Recommend for longest life 70A or less (.5C), Max continuous 135A (1C). 14.4 V recommended, 15 V max, BMS protection from over charging will cut off at 15V.

Charge Via Alternator

Drop in replacement for lead acid and AGM starter batteries for vehicles. NOTE: THE DL+ 135Ah IS LIMITED TO AN ALTERNATOR CHARGING PROFILE OF 135 AMPS OR LESS.

Includes Active BMS Protection

Contains a high discharge capable circuit that handles cell balancing, low voltage cutoff (10V) preventing over discharge, high voltage cutoff (15V) preventing over charging, short circuit protection and temperature protection for increased performance and longer life.

Internal Even-Heat Technology

Increases performance in extreme cold. When charging the battery in temperatures below 0'C/32'F DL's internal heating element will warm the cells to 0'C/32'F. This increases the lifespan, performance, and efficiency of the battery.

Certifications

All DL batteries are UN 38 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.

ISO:9001 Quality Control Certified

Engineering, design, uality control and manufacturing.

Dual Purpose Use

Multi-purpose use as a deep cycle battery and/or as a starter battery for starting gasoline engines. Marine Outboards: Please refer to your manufacturer recommendations.
