Basic Knowledge: Understanding Electric Wheelchair Lithium Batteries

Electric wheelchair lithium batteries differ significantly from traditional lead-acid batteries in terms of energy density, charge cycles, and durability. Lithium batteries typically have an energy density of around 150-200 Wh/kg, providing more power for a given weight. They can last for approximately 500 to 1,500 charge cycles, depending on usage and charging habits, compared to only 300-400 cycles for lead-acid batteries. Key terms to know include:

Step 1: Charging the Battery Correctly

To ensure optimal lifespan, always charge your lithium battery after it has been used. A full charge typically takes about 4-6 hours but can reach 78% in just 30 minutes for some modern chargers.

Step 2: Storing the Battery Properly

If you're not using your electric wheelchair for an extended period, store the battery at a 40-60% charge. This state of charge will keep it healthy and capable of lasting up to six months without significant performance degradation.
