The battery is the single most expensive component in your scooter, and it is the part most often ruined by habit rather than by age. A lithium-ion pack that is looked after can still hold around 80% of its original capacity after 500–800 full charge cycles. The same pack, charged and stored carelessly, can lose that much in a single year.
Here is what actually matters.
1. Stop charging to 100% every time
Lithium cells age fastest when they sit at very high or very low states of charge. The chemistry is under the most stress above roughly 90% and below roughly 20%.
For everyday commuting, charging to about 80–90% and topping up when you reach 20–30% will noticeably extend the pack's usable life. Save the full 100% charge for days when you genuinely need the whole range.
This is the single highest-impact habit on this list.
2. Do not leave it plugged in overnight, every night
Your charger stops when the pack is full, so there is no dramatic overcharge risk. The problem is subtler: leaving the pack sitting at 100% for eight hours every night, for years, is exactly the high-state-of-charge stress described above.
Unplug it when it finishes. If you charge overnight out of habit, use a cheap plug timer.
3. Never charge a freezing battery
This is the one that causes permanent damage fastest. Charging a lithium pack below about 0 °C causes lithium plating on the anode — metallic lithium deposits that do not dissolve back. The capacity you lose is gone for good, and in severe cases the plating creates an internal short-circuit risk.
If your scooter has been outside in winter, bring it indoors and let it warm up for at least an hour or two — longer for a large pack — before you plug it in. Riding in the cold is fine. Charging in the cold is not.
4. Store it at around half charge
If the scooter is going away for the winter, do not put it away full and do not put it away empty. Around 50–60% is the sweet spot, in a dry place at room temperature.
Check it every couple of months and top it back up to 50% if it has drifted down. A pack that self-discharges to zero and sits there can enter a deep-discharge state that a charger will refuse to recover.
5. Use the charger it came with
The supplied charger matches the pack's voltage and the current the battery management system (BMS) expects. A generic charger with a plug that happens to fit can deliver the wrong voltage or push current the BMS is not designed to handle.
If you need a spare or a replacement, buy the one specified for your model. Using the wrong charger is also one of the few things that will void a commercial warranty outright.
6. Let it cool down before charging after a hard ride
A pack that has just delivered 1200W up a long hill is warm. Charging it while it is still hot compounds the thermal stress. Give it twenty minutes.
The same applies in reverse: do not ride hard immediately after a charge in high summer.
7. Ride in a way that is kinder to the pack
Range and battery life both improve with the same habits:
- Keep your tyres properly inflated. Under-inflated pneumatic tyres increase rolling resistance significantly — you are paying for that in current draw.
- Accelerate smoothly. Repeated full-throttle launches draw the highest currents, which generate the most heat.
- Use a lower speed mode when you do not need full speed. Air resistance rises steeply with speed, so a lower mode draws less current and stretches your range — the trade-off is a longer journey time.
- Do not routinely run it to empty. Deep discharges count for more wear than shallow ones.
What normal ageing looks like
Some capacity loss is not a fault. A healthy pack loses a few per cent in its first year and then declines gradually. If your real-world range drops by 10–15% over two years of regular use, that is expected.
What is not normal, and is worth contacting us about:
- Range halving within the first few months
- The display showing a full charge that collapses to empty within a couple of kilometres
- The pack refusing to charge at all
- Any swelling, deformation, heat or smell from the battery compartment — stop using it immediately and contact us
Our warranty on batteries
Batteries are covered by a 6-month commercial warranty on scooters and 12 months on bikes, on top of your two-year statutory guarantee under EU law, which covers goods that were not as described or not of the quality you were entitled to expect at the point of sale. Gradual, normal capacity loss from use is wear rather than a defect — but a pack that fails prematurely is a different matter, and we would rather hear about it early.
