How long do wheelchair batteries last?

Power wheelchair batteries that are fully charged last up to 10 hours or about 15 miles. The battery's life depends on the amount of time and distance the wheelchair will run on one charge. As batteries age, the travel time on one charge becomes less powerful until a replacement is needed.

Battery lifespan

The lifespan of a power wheelchair battery ranges from 18 to 24 months with proper care and usage. Many factors are involved when determining when the battery may stop working. They may include activity, length, and frequency of use, weight, and correct charging habits.

Battery charting tips

The following are a few tips for charging an electric wheelchair battery and keeping it in great working condition:

• Fully charge the battery daily
• Charge the battery to at least 50% before going out
• Do not let the battery reach 0% life
• Charge for 8 hours to achieve a full charge
• Avoid charging for more than 24 hours
• Disconnect the power and remove the battery when not in use.

Battery Replacement

At some point, power wheelchair batteries will need to be replaced if the unit is frequently used. 

Most manufacturers recommend that you plan for replacement every eighteen months, especially if you notice that your battery is sluggish or does not hold as much of a charge as it used to. 

According to MK Battery, a leading global supplier of the highest quality Sealed VRLA batteries for use in deep-cycle and standby power applications, as a general rule, batteries older than two years need to be replaced. 

Slow charging is a common sign that a battery needs replacement soon and may stop functioning, which may leave you stranded.
