In this article, we introduce all details about the electric wheelchair battery. Why we choice the electric wheelchair lithium battery instead of lead acid batteries And how to prolong the lifespan of the electric wheelchair battery? etc

How Does Electric Wheelchair Battery Work?

While the battery is discharging and providing an electric current, the anode releases lithium ions to the cathode, generating a flow of electrons from one side to the other.

When plugging in the device, the opposite happens: Lithium ions are released by the cathode and received by the anode.

This process creates an electrical current that powers the electronic devices.

How Long Does Electric Wheelchair Battery Last?

Lithium electric wheelchair batteries usually last for 4,000 times cycles. However, the lead acid batteries only last 1,000 to 1,500 times cycles.

Also the lithium electric wheelchair batteries are lower maintenance than lead acid batteries. Electric wheelchair Lead acid batteries need to be kept topped up with water to protect the lead plates inside them. And they will become damaged if they are allowed to get too hot or too cold. However, the lithium battery are sealed and maintenance free.

Benefits Of Lithium Electric Wheelchair Batteries

  • Environmentally Friendly
  • Lightweight And Compact
  • High Energy Density
  • Low Maintenance
  • Long Lifespan
  • Low Self-discharge Rate

How To Choice The Electric Wheelchair Batteries?

When choosing a wheelchair battery, it is important to understand how the battery works. The battery plays a very important role in the performance of your wheelchair. Electric wheelchair batteries have 4 important parts, battery type, battery voltage, battery capacity, and current rating.

Battery Type

There are usually three types of batteries available on the market. Lead-acid, AGM battery and Lithium batteries.

Ordinary Lead Acid Battery

Lead-acid batteries are one of the most common types of batteries used for electric wheelchair. They are an affordable option with a lower initial cost and can also handle the everyday use of a electric wheelchair. They usually last about 2-3 years and usually require checking your battery to make sure there is enough water in the battery. If you are running low on water, add distilled water to prevent damage to the battery.

AGM Battery

AGM battery stands for Absorbent Glass Mat. Unlike lead-acid wet batteries, these types of batteries are completely sealed. AGM batteries are more expensive than regular lead-acid batteries, but do not require any maintenance. AGM batteries usually last 3-4 years, which is a little longer than normal lead-acid batteries.

Lithium Battery

Compared with lead-acid batteries, lithium batteries can last 10 times longer while being smaller and lighter. As well as supporting 1-2 hours of fast charging time to ensure you get the most out of your adventure.

Some other notable advantages of lithium electric wheelchair batteries include:

  • Longer Lifespan
  • Light weight
  • temperature resistance
  • 1-2 hours fast charging
  • Maintenance free
  • Lower cost per cycle
  • Safe and & Non-hazardous

Battery Voltage

Most of electric wheelchair batteries usually are 12 volts. we recommend you to check the power system to determine if more voltage is required. Also some power systems require 24 volts.

Battery Capaity

Capacity is how long the battery can work .and is expressed in ampere-hours (Ah). If an electric wheelchair runs at 10 amperes, a typical deep-cycle lead-acid battery has about 20 to 80 Ah, which means it can run continuously for 2 to 8 hours. So you can choice the best suitable capacity according to your requirements.

How To Prolong The Life Of Your Lithium Electric Wheelchair Batteries?

We all know, proper maintenance of the lithium battery, and compliance with the principles of battery use, which can greatly extend the life of the lithium battery.

Improper use of the battery will also shorten the life of the battery.

Anyway, here are a few tips to keep in mind to enable your electric wheelchair lithium battery last longer.

Charging Tips

  • Regularly charging. Under normal circumstances, when the battery is too low, there will be a reminder when your electric wheelchair lithium battery has no electricity. At this time, you need to replenish the battery in time. Although the battery electricity is too low, it will not lead to a direct safety accident, but excessive use will lead to over time. Damage to the battery structure.

(For more details about the lithium battery charging, please check our artricle 《Lithium Battery Charging: The Definitive Guide》)

  • Do not overcharge. The inside of the lithium battery cell is also composed of many components. The new battery is fine. If we use it very long time, the components function may decline. So there will have an overcharge safety risk. Generally, Overcharging your electric wheelchair lithium battery cause damage to it in the long run.
  • Use a suitable charger. Do not charge batteries with inappropriate chargers.

Using Tips

Avoid Completely Draining the electric wheelchair lithium battery

Once the battery indicator shows that the battery is getting low. Proceed straightaway to charge it.

Allowing the battery to completely drain out has an adverse effect on the lifespan of the battery. It could hamper performance.

When the battery is used up, please recharge the battery in time.

Maintenance Tips

The purpose of daily maintenance is to place the lithium battery in a suitable environment, thereby delaying the aging of the battery.

Here is two maintenance tips that we need comply with.

1. Protect against moisture.

2. And avoid direct sunlight.
