M3110-S 12.8V 110Ah Lithium Ion Engine start Battery

  • This battery meets the Sept 19, 2022 Mercury specifications for a lithium-ion engine start battery.
  • Compatible with all outboards and alternators
  • 40% more energy than a typical Group 31 AGM battery!
  • 12.8V
  • 110Ah (1,410 Whr)
  • 260 Reserve Minutes 
  • BCI Group 31 size, (13″L x 6.81″ W x 8.43″ T)
  • 31.0 lbs

M3110-S 12V 110Ah Marine Starting Battery – The M3110-S is a Lithium Ion battery for the angler who will accept no compromises in a starting battery.  This is the most cranking power that we can fit in a standard Group 31 case. (13″ L x 6.81″ W x 8.43″ T)

Storing energy in a Lithium Ion battery is one thing.  Starting an engine and charging from an alternator is quite another.  Engine start is our forté and we start some of the fastest vehicles on Earth.  How?  It features one of the most advanced internal battery management systems in the marine industry today.  This fully integrated digital battery management system insures long life and trouble free service all safely sealed inside a lightweight box.  This battery features 1,500 Marine Crank Amps (Eq) and will have no trouble starting most conventional outboard engines on the market today.  It can safely be used with any outboard charging system including Honda, Suzuki, all Mercury and all Yamaha. 

This 12V 110Ah Marine Starting Battery has a whopping 260 minutes of reserve capacity.  This is the battery of choice for boats with multiple 12″ graphs with pro anglers using this battery with up to three graphs running simultaneously.

Having trouble with graphs resetting during an engine crank?  The high power Lithium Iron Phosphate (LiFePO4) chemistry used in this battery holds a higher voltage as it is discharged eliminating this “reset” issue.  Avoid going to two 12V lead acid batteries when moving to 12″ graphs by choosing Lithium Pros!

Charging is simple because your existing 12V AGM battery compatible charger will work fine.*  Recharge times vary based on the size of the charger, outboard run time, and charging system but most anglers tell us they are “green light” on the charger before they go sleep!  That’s peace of mind.

In spite of all the power contained in this battery, it still ultra lightweight at an amazing 31 pounds!

NOTE:  Not for use in series to make higher voltage packs.  12V systems ONLY.

*Insure the charger’s float voltage is 13.5V or less and the charger never exceeds 14.8V.  Do not “de-sulfate” any lithium ion battery.

Why Lithium Pros?

MORE POWER

Power is the measure of the volume at which energy can be delivered.  Lithium Pros’ batteries have always been high power. 

Lithium Pros' batteries hold a higher voltage while loaded and recharge faster. That means a hotter ignition, faster starts, and more watts for your accessories.

LIGHTER WEIGHT

Lithium Pros' batteries are three times the energy density of comparable lead acid batteries. High energy means you can do more in the same footprint and do it with less weight.

The result is a lighter battery. In fact, some models are so light they float, making them ideal for racing and marine use.

FASTER RECHARGING

Lithium Pros’ lithium-ion batteries accept charge current up to five times faster than lead-acid batteries, and in many cases Lithium Pros’ batteries recharge in as little as an hour.

LONGER BATTERY LIFE

Lithium Pros’ LiFePO4 batteries provide over five times the cycle life at 80% DoD (depth of discharge) compared to standard lead-acid batteries, and easily handles 2,500 cycles and more.
