Battery Included

Dakota Lithium Plus 12V 135Ah Dual Purpose 1,000 CCA Battery. Complementary Jumper Cables Included 

Charger Included

12V 10A LiFePO4 charger included. Dakota Lithium 12V batteries should be charged at 14.4 volts with a LiFePO4 compatible charger. Lead acid/AGM chargers may work, but may only charge the battery to 80% of capacity.

11 Year Battery 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

12.8 Volts (V)

Engine Starting Power

Lithium battery equivalent to 1,000 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive applications. 

Size

11.6”L x12.1”W x 12.8”H (295mm x 307mm x 325mm)

Energy

1,620 Watt-hours (Wh)

Weight

42.92lbs (19.47kg) so light that it floats. 1/4-1/2 the weight of a normal car battery. 

Lifecycles (battery lifespan)

Up to 80% capacity for 5,000 cycles in recommended conditions. The typical 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

35A max continuous discharge, 1000A max 2 second pulse, 900A max 5 sec pulse. 9.0V Max discharge, 11.0V Max recommended discharge.The flat discharge voltage curve provides a 75% bigger capacity than a 135Ah SLA battery with the same CCA rating.

Ultra-Fast Charging

DL rapid charge technology allows for charging speeds of 60 minutes (135 Amps). Recommend for longest life 60A or less (1C), Max continuous 80A (1.5C). 14.4V recommended, 15V max, BMS protection from over charging will cut off at 15V. Included is a free 12V 10 Amp (A) LiFePO4 compatible charger that charges at the recommended 14.4 Volts.

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 Heating for Winter Use

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.

Cold temperature charging protection

Contains a smart BMS temperature cutoff that prevents charging when cells are below 0°C/32°F and protects the battery.

Certifications

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.

Dual Purpose Use

Multi-purpose use as a deep cycle battery and/or as a starter battery for starting gasoline engines.

Frequently Asked Questions

TWICE THE POWER?

Yes! Here at Dakota Lithium we build all of our batteries with lithium iron phosphate technology which has many distinct advantages over traditional batteries. Including 60% less weight, a charging speed that is up to 5X faster, and a significantly longer lifespan (5-10 years longer on average). One of the most noticeable advantages however is the flat voltage curve. Unlike a lead acid battery where the voltage drops as you use the battery a Dakota Lithium battery has a steady voltage for 99% of the battery's charge. That means you get all the power down to the last drop and double the usable power of traditional batteries.

ARE LITHIUM BATTERIES SAFE?

Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Dakota Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don't submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.

HOW DO I CHARGE A LITHIUM BATTERY?

Dakota Lithium batteries perform best when charged by a lithium compatible charger. Lead acid or SLA chargers, on-board chargers for AGM batteries, or other non-lithium chargers will charge a Dakota Lithium battery but only to 70-80% of capacity. This is because Dakota Lithium iron phosphate (LiFePO4) technology charges and is full at a higher voltage then traditional batteries (Dakota Lithium charges at 14.4 Volts). Chargers with a lithium battery setting or designed for lithium will charge at the appropriate voltage.  For troubleshooting tips download the Dakota Lithium battery user manual here.

WILL COLD WEATHER AFFECT MY BATTERY?

Your Dakota Lithium battery will discharge normally between a range of -20F and 120F (-29C to 49C). DL batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter).
