RJ TECH 12V marine batteries are similar-sized to lead-acid batteries, which makes upgrading to RJ TECH Lithium 12V Batteries a simple task, while offering six times the battery life and less than a third of the weight of lead-acid batteries.


RJ TECH Lithium Batteries are built for starting, with increased peak amps for starting motors, electric start generators and other high-amp-draw devices ,  lightweight yet, due to their superior construction, they are very strong and durable. They are able to withstand extreme levels of vibrations and shocks and are most suited for military, marine  applications.
