The battery is the heart of any mobility scooter. The choice between sealed lead-acid (SLA) and lithium-ion changes weight, range, lifespan and price.
Weight and handling
Lithium packs are typically 50-60% lighter than equivalent SLA. For portable models that users lift daily, that difference is decisive.
Lifespan
SLA lasts ~300-500 cycles; quality lithium lasts 800-1200 cycles. Over a 3-year ownership, lithium is usually cheaper per cycle.
Range and charge
Lithium holds voltage flatter, so usable range stays consistent until empty, and it charges faster. See our lithium maintenance guide.
Safety and certification
Both must meet UN38.3 and transport rules. Our lithium packs add over-temperature and over-current protection and ship with CE/ISO documentation.
Which to choose?
- Value / infrequent use: SLA keeps the sticker price low.
- Daily / portable / longer ownership: lithium wins on total cost and experience.
