JMT 12V maintenance free Lithium-Ion direct replacement battery
By replacing your standard lead-acid battery with a JMT lithium-ion battery, you can save up to 5 kg of weight.
Due to the properties of a Lead-acid batteries, they can only use approx 30% of their capacity, while nearly 100% of the capacity is available for a lithium-ion battery. As a result, the lithium versions of the JMT battery requires only 1/3 the capacity of a comparable lead-acid battery for the same starting power.
JMT use a built in processor (or Balancer) to ensure a uniform state of charge of all cells.
The dimensions of the lithium-ion battery match the dimensions of the original lead-acid batteries (sometimes using adapters) and the connections are identical, therefore the battery is a direct replacement for the original. Due to the lack of acid, a Lithium battery can be mounted in any position and is suitable for use in temperatures of up to 60°C
- Approx. 1/3 of the weight of the comparable lead-acid battery
- Unbeatable cost / weight savings ratio
- Can be installed in any position, as there is no acid
- Contains no heavy metals
- Fast charging using an appropriate charger (up to 90% in 6 min)
- Low self-discharge (max 5% per month)
- safe technology and long service life
- 12 V maintenance-free lithium-ion battery
- Charging current recommended at 1 A
- maximum charge current for fast charge 12 A
- 2.4Ah - standard 10Ah
- Dimensions - 113x105x69mm
- Comparable in dimensions and connections with the Yuasa YTZ7S/YTX7L/TTZ7S
Please note that you must only use a suitable Lithium Ion battery charger - please see our Lithium Optimate charger.
Under no circumstances should chargers be used which attempt to desulphurate deep-discharged batteries under 10 volts with a voltage of more than 14.9 volts before they begin the actual charge.
The maximum charging voltage of 14.9 volts must never be exceeded.
