Lead-acid batteries only use 30% of their capacity whilst nearly 100% of the capacity of lithium-ion batteries is used. For this reason, lithium versions of JMT batteries need only 1/3 of the capacity of a comparable lead-acid battery for the same starting power. 

JMT lithium-ion batteries have the following benefits: 

• About 1/3 of the weight of comparable lead acid batteries
• Can be mounted in any position - no acid spillage  
• Fast charging with high ampage systems (up to 90% fully charged in only 6 minutes) 
• Very low self-discharge - long shelf life 
• Excellent performance at high temperatures
• High durability
