Advantages of Lithium Batteries

Lithium batteries

Lithium batteries are fast replacing traditional sealed lead-acid (SLA) batteries as the standard for mobility scooters and electric wheelchairs, despite being 3 times as costly. Why is this so?

There's a "3-3s" saying in the industry when we discuss about lithium batteries.

Lithium batteries are 3 times the cost, 1/3 the weight, and have 3 times the life span of SLA batteries.

So even though lithium batteries cost 3 times more, they don't need to be replaced as often as lead-acid batteries. Lead acid batteries on mobility scooters or motorised wheelchairs typically need to be replaced between 12 to 18 months.

But for lithium batteries, their life span can stretch to 3 to 5 years. So over the course of time, lithium batteries are not really more expensive than lead-acid batteries.

They weight savings, however, are yours to keep! So despite the high cost, lithium battery powered personal mobility aids (PMAs) are definitely worth considering.
