Spacer (S)
Batteries may be equipped with one or more spacers that are taped with adhesive tape under the battery so that the battery fits exactly into the original battery box.
Indicator (I)
All batteries are equipped with a battery condition indicator. Simply press the test button. When all three blue LEDs light up the battery is fully charged(ful). If it lights only 2 LEDs, it is only half charged (med). When only one LED is lit (low), the battery must be charged immediately.
Replacing a standard lead-acid battery by a JMT lithium-ion batter can save you up to up to 5 kg in weight with minimum effort.
JMT lithium-ion batteries have the following benefits:
- About 1/3 of the weight of comparable lead acid battery
- Unbeatable ratio of cost/weight savings
- Can be mounted in any position - no acid spillage
- Does not contain heavy metals
- Balanced discharge/charge of all cells by the integral balancer
- Fast charging with high ampage systems (up to 90% fully charged in only 6 minutes)
- Very low self-discharge - long shelf life (up to 5% per month)
- Excellent performance at high temperatures (even up to 60° C)
- Safe technology and high durability
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.
A uniform charging of all the cells is ensured by a built-in processor (the "balancer").
The dimensions of the lithium-ion batteries (using adapters where necessary)correspond to the dimensions of the original lead-acid batteries and the connections are identical, thus the battery can be replaced easily in a few minutes.
*** IMPORTANT ***
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.
Although this lightweight battery is extremely suitable for everyday use, it should be noted that the starting capacity is reduced at temperatures below zero degrees Celsius.
Technology - JMT lithium-ion batteries are manufactured using a cathode material of iron phosphate (LiFePO4) and lithium-polymer. The technology and the manufacturing process ensure the highest safety standard for lithium batteries.
