The manufacturer's aging benchmark: 1.5–2 years
The most concrete service-life statement in the AMOTO published material appears in the A41 fault guidance: battery aging commonly appears after 1.5–2 years of use. That single sentence is more useful than the round numbers thrown around the industry, because it sets a planning horizon for that vehicle: a fleet or a dealer running A41s should expect to assess that model's pack health — range against the published figure, behaviour under load — from around the eighteen-month mark, and should treat noticeable aging inside that window as a warranty-and-service conversation rather than a surprise. The catalog publishes no equivalent benchmark for the range's other packs.
Read the benchmark correctly, though: "aging commonly appears" is not "the battery dies at two years". Aging means the pack no longer delivers its as-new range — the published range figures (40 km for the A11's 48V 20Ah; 60–70 km for the 60V 32Ah class; up to 140 km for the dual-battery Citycoco fitment) are as-new figures, and an aged pack delivers a shrinking fraction of them. How fast the fraction shrinks is exactly what the rest of this guide is about.
What ages a pack fastest
The manufacturer's guidance points at the same behaviours from several directions. Running a lithium pack to complete discharge before charging is named directly in the manufacturer's A41 battery guidance: it says not to do it, and pairs it with the working rule of charging when the remaining charge falls below 20%. That guidance was written for the A41's pack; we cite it as the manufacturer's own published battery-care position, not as a per-model rule for every vehicle in the range.
Storage is the second factor. A pack stored fully discharged — the end-of-season scooter left in a shed — combines deep discharge with time; the winter guide covers storage practice. Heat is the third: the published fault material lists overheating and swelling among battery fault symptoms.
Lead-acid packs: a different clock
Much of this range runs lead-acid: the A11's specification page names a lead-acid 48V 20Ah battery, the ZL8/ZL9 motorcycles publish 60V 32Ah lead-acid, the A31's agricultural variant names lead-acid at 72V 58Ah, and most mobility listings are lead-acid. Lead-acid service life is conventionally counted in charge cycles and is highly sensitive to depth of discharge. The catalog does not publish cycle-life figures for its lead-acid packs, and this guide will not import figures from other manufacturers' batteries. For lead-acid models, note what does not transfer: the 1.5–2 year benchmark and the below-20% rule both come from guidance written for the A41's lithium battery. The catalog publishes no aging benchmark for its lead-acid packs, so for those models service life is a measurement matter — the fixed-route method in the next section — not a borrowed calendar figure.
Signs the pack is aging
- Range loss against the published figure on the same route, same load, same season — the cleanest signal, which is why recording early-life range matters.
- Voltage drop under load — the fault guidance lists battery voltage drop as a distinct symptom; a pack that sags on hills it used to climb is telling you about its internal resistance.
- Charging behaviour changes — charging that finishes suspiciously fast (less capacity to fill) or never finishes both belong in the troubleshooting conversation.
- Physical symptoms — swelling or leakage are not aging, they are end-of-life: stop using the pack and move to the replacement guide.
Planning around the honest answer
So: how long does the battery last? The manufacturer's one published position — the A41's — is that aging commonly appears after 1.5–2 years; how long a pack serves usefully beyond its early years depends on chemistry, discharge habits, storage and temperature, in roughly that order of the owner's control. Dealers should price that reality into fleet offers (a mid-contract pack assessment is a selling point, not an admission), and private buyers should ask, at purchase, what the replacement pack for their model costs and how it is supplied — the removable-pack models (EH01, EH02) make that conversation easiest, because the replacement is a swap, not a workshop job. The platform page maps which models run which chemistry and capacity, model by model.
Measuring your own pack's aging
The A41 benchmark is a population statement about that model's packs; your pack has its own curve, and you can measure it with nothing more than a fixed route and a notebook. When the vehicle is new, ride your standard route — same load, same pace — and record the state of charge used. Repeat the identical ride each season. The comparison, not any single ride, is the aging measure: a pack that used 40% of its charge for the route when new and uses 55% two years later has told you its capacity story precisely, whatever the calendar says. Fleets should log this per vehicle at the monthly round (it sits naturally beside the brake and tire checks in the maintenance checklist), because the log converts a warranty conversation from opinion into evidence — and because a fleet that can see one vehicle's curve bending early can plan its replacement pack into a routine order instead of an emergency one.
Two questions to ask before you buy
The service-life conversation is easiest before the purchase, and two questions cover it. First: what does the replacement pack for this model cost, and is it supplied as a swap (as with the removable EH packs) or a workshop fit? Second: which published figure should I hold the pack to — the model's range as published, on which route profile? A seller who can answer both has thought about the vehicle's second year, not just its first week. A seller who cannot is telling you the battery is, for them, a fit-and-forget item — which, per the manufacturer's own aging benchmark, it is not.
The short answer, restated
For the A41's lithium pack, the manufacturer's published position is the one this guide opened with: aging commonly appears after 1.5–2 years, and the same guidance pairs that benchmark with the below-20% charging rule. The guidance publishes no service-life figure beyond that benchmark, and this guide adds none. For the range's other packs the catalog publishes no equivalent expectation; the measurement method above is the honest substitute.
