The types of common wheelchair batteries

There are several types of batteries used in electric wheelchairs, each with its own characteristics and suitability for specific wheelchair types. The commonly used types include:

1. Sealed Lead Acid (SLA) Batteries

Sealed Lead Acid (SLA) Batteries are usually suitable for standard electric wheelchairs.It has many advantages:

• Safety: SLA batteries are designed with a sealed construction, which means they do not release harmful gases or electrolytes during normal operation.

• Maintenance-free: SLA batteries are typically maintenance-free, as they do not require regular topping up of electrolyte or water.

• Cost-effectiveness: SLA batteries are generally more affordable compared to other types of rechargeable batteries, such as lithium-ion batteries.

• Long shelf life: SLA batteries have a relatively long shelf life and can retain their charge for extended periods when not in use.

The disadvantages of SLA batteries are also obvious:

• Too heavy: SLA batteries have a lower energy density. This means SLA batteries tend to be bulkier and heavier for the same amount of energy stored.

• Limited cycle life: SLA batteries have a limited number of charge-discharge cycles.

• Low charge retention: SLA batteries have a relatively high self-discharge rate, meaning they gradually lose their charge over time, even when not in use.

• Slower charging time: SLA batteries typically have longer charging times.

• Environmental considerations: SLA batteries contain lead, which is a toxic material. Improper disposal or mishandling of SLA batteries can pose a risk to the environment and human health.

• Not airline-approved:You can not take a Sealed Lead Acid Wheelchair to the plane.

2.  Gel Batteries

Gel batteries, also known as gel cell batteries or valve-regulated lead-acid (VRLA) gel batteries, are a type of sealed lead-acid (SLA) battery.It is ideal for power wheelchairs and scooters.Here are the advantages of this kind of battery.

• Safety: Gel batteries have a sealed construction, which eliminates the risk of acid spills or leaks.

• Deep-cycle capabilities: Gel batteries are designed for deep-cycle applications, allowing them to be discharged and recharged repeatedly without significant degradation in performance.

• Vibration resistance:Gel batteries are more resistant to vibrations. This makes them suitable  for applications where the battery may experience regular movement or jolts, such as in wheelchairs that are used outdoors or on uneven terrain.

• Maintenance-free: Like other SLA batteries, gel batteries are maintenance-free.

Gel battery also has it’s disadvantages:

• Lower energy density: It would be much heavier and may limit the range or maneuverability of the wheelchair.

• Slower charging rate: Gel batteries have a slower charging rate compared to some other battery types. Sensitivity to high temperatures: Gel batteries are more sensitive to high temperatures compared to other battery types. 

• Cost: Gel batteries are generally more expensive than traditional flooded lead-acid batteries.

• Not airplane-approved: It is same as the SLA batteries.

3. Lithium-Ion (Li-ion) Batteries:

Lithium-ion (Li-ion) batteries are a type of rechargeable battery widely used in various applications, including electric wheelchairs. It has many unique features compared to lead acid batteries.

• High energy density:Li-ion batteries have a higher energy density.This means they can store more energy per unit of weight or volume, allowing for a higher capacity in a smaller and lighter package.
