Batteries should last an average of 1 to 1.5 years.
These are some Factors that affect battery performance:
Maintenance - Poor maintenance.
Charging - Improper charging shortens battery life.
Chair Components - Malfunctioning electronics, bad motors, electric brakes, and corroded
wiring are also capable of degrading the battery performance.
Battery Servicing and Replacement
Automobile batteries, which are used for starting, are tested with a load tester to assure a high rate of
energy production in a short burst.
Deep-cycle batteries produce energy more slowly and are designed to hold up to constant
discharging and recharging. Testing a deep-cycle wheelchair or scooter battery requires different
procedures than an automobile battery.
A routine for testing deep-cycle batteries should follow these guidelines:
Never replace just one battery at a time. This will create an imbalance when charging and ultimately
damage both batteries.
Check batteries for a voltage difference. A voltage difference of more than .4 volts D.C. is a true
indicator of a bad battery.
Voltage test - A dead battery cannot be effectively tested, yet many people mistakenly try to do just
that.
Any battery that reads 11.0 volts or less is technically dead.
To perform any testing, especially a load test:
A. Batteries must be charged
B. The top charge must be taken from fully charged batteries if charge rate has just nished.
The voltmeters on load testers are not accurate enough to establish a state of charge.
Load Test - This test can only be done on fully charged batteries and can only diagnose one
type of problem, an internal short.
Capacity/Discharge Test - This is the only accurate way to test a deep-cycle battery for adequate
running time. The problem with this test is that it is time consuming.
Current / Voltage check with a regular interval check - Another way of truly knowing how much
time your battery will last, but it is also time consuming.
