Will an electric scooter battery be damaged if left uncharged for several months?

An electric scooter battery can be damaged if left uncharged for several months. Here are some relevant introductions about batteries: 1. Lead-acid battery: The most common type is the lead-acid battery, whose electrodes are made of lead and lead oxide, with a sulfuric acid solution as the electrolyte. It is inexpensive and has stable voltage, but requires frequent maintenance and has a relatively short lifespan, typically around 3 years under normal usage. 2. Maintenance-free battery: Compared to lead-acid batteries, it consumes very little electrolyte, requires almost no maintenance, and features high-temperature resistance, compact size, and low self-discharge. However, it is more expensive, costing twice as much as a lead-acid battery, and has a similar replacement cycle of around 3 years under normal conditions. 3. AGM battery: Cars equipped with auto start-stop functionality require a more robust battery to operate properly. The specialized AGM battery uses ultra-fine glass wool material, which provides stronger cyclic charging capability and a longer lifespan, lasting 4-6 years under normal usage. Additionally, this battery offers better low-temperature starting performance and more stable capacity during use, but it is the most expensive option.
Leaving an electric bike battery uncharged for several months can indeed cause problems. I've previously researched electric vehicle battery maintenance. Lead-acid batteries discharge relatively quickly on their own. If left unused for a quarter without charging, the voltage drop can lead to the formation of sulfide crystals inside, reduced electrode activity, and irreversible capacity loss. Lithium batteries are similar - they dislike deep discharge states. If left for months below the critical voltage, the positive and negative electrode materials get damaged, significantly shortening lifespan. I recommend that regardless of battery type, check the charge level every 2-3 months during periods of non-use and maintain at least 50% charge. Store in a cool, dry place - avoid hot, humid garages. Developing this habit can extend battery life to 3-5 years without issues, saving you the trouble of replacement. New batteries are expensive, so regular maintenance is the most cost-effective approach.
