6 Key Differences Between Lithium Battery and Lead-Acid Battery Wheelchairs

6 Key Differences Between Lithium Battery and Lead-Acid Battery Wheelchairs

The market for lithium battery-powered wheelchairs is rapidly growing, sparking curiosity about why they’re becoming so popular. What sets these models apart from traditional lead-acid battery wheelchairs? Here are the primary distinctions you should know:

Weight

 
Lithium battery wheelchairs are significantly lighter compared to lead-acid battery wheelchairs. If you’re in the market for a portable and easy-to-transport electric wheelchair, a lithium battery option is your best bet.

Lifespan

 
Lead-acid batteries generally last up to 2 years. In contrast, lithium-ion batteries have a lifespan that is at least two to three times longer, offering better long-term reliability and fewer replacements.

Maximum Driving Distance

 
Given the same battery capacity, wheelchairs powered by lithium batteries can travel much farther than those using lead-acid batteries. This efficiency stems from the lighter weight of lithium batteries, which translates into better power management and greater travel range.

Charging Time

 
Lead-acid batteries typically require around 10 hours to fully charge. On the other hand, lithium batteries charge significantly faster, ranging from 3 hours to just a few minutes, depending on the battery size.

Safety

 
Modern lead-acid batteries are Valve Regulated Lead-Acid (VRLA) and maintenance-free, making them relatively safe. While pure lithium is highly flammable when exposed to air, lithium batteries in wheelchairs are equipped with advanced Battery Management Systems (BMS) to prevent overcharging and discharging, enhancing safety.

Cost

 
Lead-acid batteries are generally more affordable than lithium batteries. If you have basic requirements and prioritize cost savings, a lead-acid battery wheelchair could be a practical choice. However, for a compact, foldable, and highly portable electric wheelchair, lithium battery models are a better fit despite the higher upfront cost.
