Let's take a closer look at the features that make E3.501 the LAST battery you'll ever buy!

Lighter Weight

The E3.501 weighs just 26 pounds well less than half of the lead-acid battery that it is replacing. Cutting battery weight means more power, increased fuel economy and better overall performance from your vehicle.

Dynamic Charge Acceptance

E3.501 offers an extremely robust 12 volt platform that can accept high rates of charge while capturing and storing several times more energy. That means that the battery is highly versatile and can power both traditional 12 volt automotive systems and those that utilize regenerative braking and/or start-stop systems. This advantage is sustained over product life and does not suffer the severe performance degradation experienced with lead-acid technologies.


Extreme Cold Temperature Performance

E3’s breakthrough Lithium-ion chemistry delivers a wider temperature operating range for exceptional cold crank performance that outperforms lead acid batteries, thus contributing to overall system reliability.


Extensive Cycle Life – the LAST battery you’ll ever buy

While some lithium battery producers claim extended life of 3 times over a lead acid battery, E3 Lithium’s UltraPhosphate Technology delivers a solution that will perform for the life of your vehicle. This is truly the last battery you’ll ever buy.


Exceptional Reliability & Durability

Our smart on-board battery management system (BMS) electronics report real-time data and diagnostics to protect the battery and prevent premature failures.

The integrated BMS provides cell balancing and built-in state of charge and state of health measurement and calculation which allows automobile manufacturers to remove intelligent battery sensors from their vehicle system. In other words, all E3 Lithium Batteries are built to OEM specifications, which means that they are safer, more reliable and more durable than other non-factory standard lithium batteries on the market today.


Incomparable Versatility

E3.501 featuring UltraPhosphate Technology is designed to work in a multitude of different vehicle applications. From the race track to the street, E3.501 is capable of powering everything from a NASCAR Monster Energy Cup car to an Off-Road Trophy Truck to your 1934 Deuce Coupe and everything in between.

10 Year Limited Warranty

We're so confident in the performance of our lithium batteries, E3.501 carries a 10 year limited warranty that includes a 5 year free replacement. Find out more by visiting the Warranty section of the website.
