Electric Wheelchair Battery Solution

Support everyday mobility with dependable range, smooth power delivery and maintenance-free battery options.

Dependable Power for Everyday Mobility

For an electric wheelchair user, battery performance shapes how confidently each day can be planned. The battery must provide consistent energy for acceleration, steering, gradients and uneven surfaces while also supporting controls, powered seating and other onboard functions. Daily charging, repeated cycling, temperature changes and occasional deep discharge can all affect usable range and service life.

LEOCH addresses these requirements with cycle-focused AGM, gel, AGM-GEL and patented carbon nanotube lead-acid technologies. Available across different capacities and physical formats, our batteries support everything from compact indoor chairs to higher-capacity outdoor and rehabilitation models. By matching voltage, capacity, dimensions, terminals and charging requirements to the wheelchair, LEOCH helps manufacturers, distributors and mobility service providers deliver dependable power for everyday movement.

More Effective Recovery for Everyday Mobility

Explore Carbon Nanotube Technology

Frequent cycling and incomplete recharging can gradually reduce the usable capacity of conventional lead-acid batteries. LEOCH’s patented Carbon Nanotube Technology improves conductivity and charge acceptance, while advanced alloy, separator and nanoscale silicon technologies help strengthen corrosion resistance, improve electrolyte utilization and reduce stratification. Applied in the LTC Series, these enhancements support longer cycle performance and more effective energy recovery between periods of use—providing an advanced lead-acid option for electric wheelchairs relied upon throughout the day.

FAQs

Q. Does a shallower depth of discharge always extend battery service life?

Not exactly. While shallow discharge causes less instantaneous damage to battery plates, persistent partial discharge leaves large portions of active materials unreacted inside the cells, which tends to trigger irreversible sulfation. Progressive sulfation gradually reduces usable battery capacity and degrades runtime performance.
Q. What maintenance steps are required for batteries if equipment will be out of service for a long period?

Fully charge the batteries prior to long-term storage. Perform a supplementary top-up charge once every month during storage. If the equipment is fitted with a master disconnect switch, turn it off to cut no-load circuit and minimize standby self-discharge loss.
Q. Can the original charger be reused when replacing flooded batteries with AGM batteries or vice versa?

They are not interchangeable. Flooded batteries require a higher charging voltage. If an original flooded-battery charger is used for AGM batteries, the excessive charging voltage will accelerate electrolyte dehydration and cause AGM cell bulging and premature failure. Conversely, when flooded batteries replace original AGM units, the AGM-specific charger delivers insufficient voltage to fully charge flooded batteries, leading to chronic undercharging and drastically shortened service life over time.
Q. Why will a lithium battery not charge—or appear fully charged but lose power quickly?

Several issues can cause this behaviour. A large voltage difference between cells may trigger BMS protection and substantially reduce usable capacity. The BMS itself may also have a fault affecting cell balancing, charging or discharge control.
A weakened cell with high internal resistance can limit the performance of the entire battery pack. An incompatible, aging or faulty charger may also prevent the battery from charging correctly. If the problem persists, stop using the battery and have the pack, BMS and charger inspected by a qualified technician. Do not bypass the BMS or continue operating a battery that overheats, swells or shows visible damage.
Q. Why are low-speed electric vehicles commonly powered by LiFePO₄ batteries?

LiFePO₄ is widely used because it offers strong thermal stability, long cycle life and competitive lifecycle value. Its lower risk of thermal runaway makes it well suited to low-speed vehicles operating across uneven roads, frequent cycling and varied working environments.
Compared with ternary lithium chemistries such as NMC, LiFePO₄ generally offers lower material costs and greater cycle endurance. Although ternary lithium can provide higher energy density and stronger low-temperature performance, these advantages are often less important in short-distance, low-speed applications where safety, durability and cost are the main priorities.
Q. What maintenance do low-voltage motive lithium batteries require?

Always use a charger, wiring harness and connectors that match the battery specifications. Frequent high-current operation—such as prolonged climbing under maximum load or repeated hard acceleration—can accelerate cell aging.
Store the battery in a cool, dry environment away from direct sunlight, rain and extreme temperatures. For extended storage, maintain approximately 50% state of charge, avoid leaving the battery below 20%, and check and recharge it at least every three months or according to the manufacturer's instructions. Charging conditions, discharge depth, operating temperature, load and storage state of charge can all affect service life.
Q. Can a low-voltage lithium battery directly replace a lead-acid battery?

In many applications, a lithium battery with the same nominal voltage can replace an existing lead-acid battery, but compatibility must be confirmed first. Check the battery dimensions, mounting arrangement, terminal polarity, wiring, controller requirements, discharge current and communication interface where applicable.
A compatible lithium battery charger must also be used, as lead-acid and lithium batteries require different charging profiles. Depending on the battery capacity, vehicle efficiency, payload and operating conditions, a suitable conversion may extend driving range while reducing weight, routine maintenance and the risk of acid leakage.
Q. How do low-voltage motive lithium batteries differ from high-voltage EV batteries?

Low-voltage motive batteries commonly operate at 36V, 48V, 60V or 72V and are used in golf carts, sightseeing vehicles, forklifts, electric three-wheelers and similar equipment. Passenger EVs and electric trucks generally use high-voltage battery platforms operating at 300V or above.
Because their voltage levels and vehicle architectures differ, low-voltage systems typically have a simpler electrical protection architecture. High-voltage EV batteries require additional safeguards such as high-voltage insulation monitoring, interlock circuits and comprehensive electrical isolation.
