Batteries should last an average of 1 to 1.5 years.

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 just some of the factors that may affect

battery life and 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.

The voltmeters on load testers are not accurate enough to

establish a state of charge.

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 ﬁ nished.

Load Test• - This test can only be done on fully charged batteries and can

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 is also time consuming.
