12V 100AH Lithium Ion Battery | Deep Cycle | Engine Starting

A Drop In Replacement & Upgrade from AGM, Gel or Lead Acid Batteries.

Our Lithium Ion Batteries are the ideal battery for any application that currently uses a AGM, GEL or lead acid batteries. Chargex Battery gives you the ability to upgrade your current batteries to lithium ion technology that can last over 5000 cycles and has tremendous advantages in weight, performance, reliability and life compared to that of traditional lead acid batteries.

The (CX100) 12V 100AH Lithium Ion Battery has a fully automatic built in battery protection system (BPS) designed to automatically disconnect power to the terminal posts if the battery is drained below 8V preventing damage to the battery from accidentally discharging. Connect multiple batteries in series or parallel to increase capacity and voltage.

100% DOD (depth of discharge)

Lithium Ion Batteries allow you to use 100% of the rated capacity whereas agm batteries typically recommend not to drain below 50%

70% Lighter than lead

Lithium Ion Batteries are typically 70% lighter than the same size lead battery

Long Life

Lithium Ion Batteries can last 3000 - 5000 cycles whereas most lead batteries can last 300 - 500 cycles

Zero Maintenance

Lithium Ion Batteries require no maintenance and can hold a full charge for over 1 year

Built In Battery Protection

Every Chargex Battery has a built in fully automatic battery management designed to protect the battery from:

  • Low Voltage
  • Over Voltage
  • Short Circuit
  • Reverse Polarity

these features help protect the  lithium ion core and your investment.

99.1% Efficient 

Chargex Battery Lithium Ion Batteries are 99.1% efficient and do not heat up during use or charging like lead batteries

5 Year Warranty

Chargex Batteries come with a 5 year warranty and are repairable for life.

No Voltage Drop

Smart Battery Voltage Discharge Graph

Chargex Battery Lithium Ion Batteries have no voltage drop during use. For Marine use this means faster cranking for hard to start engines, Stronger bilge and live well pumps, Brighter Lights and No voltage drop for inverters and voltage sensitive relays.
