Wheelchair Batteries for Dummies :
99% of all Mobility Scooters and Power
Wheelchairs use Two, 12 Volt Sealed Lead
Acid Batteries. The two batteries are
mainly wired in "series" to produce 24
Volts.
Amp Hours is the second major factor
when looking at batteries. Basically an
Amp Hour (Ah) is the amount of energy a
battery holds. The more Amp Hours in a
battery the further the mobility vehicle
will go. Sounds great but your mobility
vehicle is limited to certain size
batteries which limits the amount of Amp
Hours.
- 12
Volt - 12Ah or 15Ah, both are the
Same size. Usually used in small
portable vehicles.
- 12
Volt - 18Ah or 22 Ah, again, both
are same dimensions. Usually used in
small portable vehicles to help
extend the range.
- 12
Volt - 31Ah to 36Ah, these are known
as U1 Batteries and dimensions are
similar. Mainly used in mid size
mobility vehicles.
- 12
Volt - 55Ah, known as NF-22 or NF22
Batteries. Mainly used in large size
high weight capacity mobility
vehicles.
- 12
Volt - 75Ah, known as Group 24
Batteries. Used mainly in Heavy Duty
mobility vehicles.
In
addition, if you have a mobility vehicle
that uses 12 Volt - 12Ah batteries you
can always upgrade to 12 Volt - 15 Ah
batteries due to both being the same
size. The same works for 12 Volt - 18Ah
batteries, the 12 Volt - 22Ah Batteries
are the same size.
