Why do Lithium batteries last longer than Lead-acid?
The nature of Lithium and the integrated Battery Management System (BMS), allow Lithium batteries to last five times longer than Lead-acid.
If you opened the casing (which we definitely don't recommend!), you would see that a Lithium battery consists of a number of individual power cells which are joined together to offer the required capacity (number of holes you can play). The Battery Management system is a really clever piece of kit (think of it as a mini computer), which performs a vital role in keeping the battery components safe, while allowing each power cell to discharge at an even rate. This system spreads the 'load' on the cells and reduces cell damage to maintain capacity for as long as possible.
Can I top-up my battery between rounds?
Another benefit of Lithium batteries is that they can take a 'top-up' charge. What does this mean? In practical terms, it means that it does not need a full charging cycle to 'top-up' the capacity (number of holes you can play). A common scenario would be a golfer who is playing 36 holes in a single day and decides to put their battery on charge between rounds. The capacity will be topped up for as long as the battery is on charge, which might come in VERY handy after a long and tiring day out on the links! This is very different from a traditional Lead-acid battery, which is only worth charging for a full cycle - that's a minimum of eight hours! In addition to this, a Lithium battery takes a speedy 4-5 hours to fully charge from empty - that's got to be good for your electricity bill!
Should I leave my battery on charge all the time?
No is the simple answer, because you really don't need to and it is always safer (plus greener) to leave appliances unplugged if possible!
Don't worry though - your Lithium battery and its dedicated charger are designed to 'switch off' once fully-charged to reduce the risk of continual charging and the potential for overheating. We therefore recommend waiting for the charger light to change from red to green, before switching off at the wall and unplugging the battery from the charger. This doesn't damage the battery and the battery will hold its charge until you next play.
