Lithium Battery Guide Do’s and Dont’s
Save yourself time, stress and money before swapping out your standard battery for a lithium. The pros of a lithium are numerous, but use it incorrectly and you can pay the price.
It only takes a couple of minutes.
It is imperative that you take the time to read this information, as many people think that swapping out a conventional battery on their bike for a small lighter Lithium battery is a simple procedure. There are several pitfalls that can occur, the main being you are out of pocket as you will need a new battery.
PLEASE read everything below to save yourself time and money in the future.
If your lithium battery charge is below 11.5 volts – YOU WILL DAMAGE IT
If your battery overcharges above 14.5 volts (even momentarily) it will be damaged. Prolonged overcharging (even for a few minutes) could result in fire, explosion and or personal injury.
A parasitic battery drain is when abnormal and continuous discharge of power occurs after having shut off the engine. Usually, this is caused by a short circuit or an electrical device that remains in the “on” position or energized, such as:
- A GPS or Tracking Device
- An Alarm or Immobaliser
- A switch
- A computer module
- An unknown electrical fault
Overcharging a Lithium Battery can occur if the alternator on your bike produces more volts than the battery is designed to hold. This can be more common in older bikes, so it is essential to check the voltage of your bike.
Over-discharging can occur when you have a parasitic drain on your bike ie: if you have a tracker fitted that runs off the battery. If you go for periods without using the bike or without charging the battery, the tracker will be constantly drawing on the batteries power. If the batteries voltage falls below 11.5V you run the risk of over discharge and the battery may not be able to be recovered.
Another example of over-discharge is repeatedly attempting to start the engine. If you have the correct battery the engine (if the engine is set up correctly) should start the 1st or 2nd time. If you repeatedly try to start the engine this can cause an over-discharge, as unlike a conventional battery which keeps going until it runs out of power, a lithium will keep going giving full power until it drops below 11.5v, then that’s it. Unlike a conventional battery which can be recharged, a lithium may not be able to recover.
TOP TIP: If your bike does not like cold / winter starts, turn your headlights on for a few seconds first. This will draw a little heat into the lithium battery. Turn off lights then attempt to start the bike.
