JMT lithium-ion battery for Harley Davidson
By replacing a standard lead-acid battery with a JMT lithium-ion battery up to 5 kg in weight can be saved, without any appreciable effort.

Following advantages speak for JMT lithium-ion batteries:
  • About 1/3 of the weight of comparable lead acid battery
  • Unbeatable ratio of cost / weight saving
  • Because it contains no acid, can be mounted in any position
  • Contains no heavy metals
  • Balanced discharge / charge of all cells by Balancer
  • Fast charging with high charging current (up to 90% in 6 min)
  • Very low self-discharge (max. 5% per month)
  • Even at high temperatures still good performance up to 60 ° C
  • Safe technology and high durability
  • Special black, roughened surface for optimum "look"
  • Very high cold starting power
  • Excellent vibration resistance
  • Highly durable pole connections ensure a smooth start and a long lifespan
  • Will be delivered with a terminal cover, also in black
Lead-acid batteries can be used only 30% of its capacity due to the specific characteristics, while nearly 100% of the capacity can be used in lithium ion batteries. For this reason, lithium version of JMT batteries for the same starting power need only 1/3 of the capacity of a comparable lead-acid battery.
A steady state of charge of all cells is also ensured by a built-in processor ( "balancer").
Although JMT lithium-ion batteries discharge at a slower rate than coventional batteries it is vital that they are not allowed to go completely flat. Please regularly use the charge indicator on the top of the battey to assess it's state of charge especially if the bike has not been ridden for some time.

JMT lithium-ion batteries can be charged with conventional chargers but it is best to check that the charger is suitable for a lithium-ion battery. Some maintenance chargers have a recovery mode for sulphated lead acid batteries. These chargers should not be used with a lithium-ion battery as in recovery mode high voltage levels can damage them irreparably. If in doubt purchase a battery charger suitable for lithium-ion such as some of the examples below.
The manufacturer guarantees a sufficient initial capacity of up to -5 degrees Celsius.


JMT use lithium-ion batteries as a cathode material iron phosphate (LiFePO4), and use the lithium-polymer process in the manufacture. This allows them to rise even explode either in flames during normal operation.

The technology and the manufacturing process ensure the highest safety standards for lithium batteries.
