SLA BATTERY MAINTENANCE
Keeping the Sealed Lead Acid battery in top condition is the key to your
Vexilar system’s reliability. Follow these basic tips and you can expect
years of dependability from your Vexilar equipment:
SLA Battery Do’s
• Allow the SLA battery to fully recharge at room temperature
before use. Recharge the battery after each use.
• Give cold batteries extra time to charge. Charge at room
temperature if you can.
• Keep ames, sparks and metal objects away from batteries and
terminals.
• Keep the battery clean and dry.
• Charge periodically during battery storage.
• Disconnect the battery or turn the Master Power Switch o when
not in use.
SLA Battery Don’ts
• Do not over-discharge the battery. You should never drain a battery
beyond 80%, meaning less than 20% left. Make sure any other
devices are disconnected from the battery before storage.
• Do not overcharge the battery. Measure the voltage of the battery
while charging. It should never go over 15 volts. Your Vexilar
charger is designed to provide an optimal charge to your battery.
Please only use Vexilar chargers.
• Do not damage the battery or terminals by dropping. Your battery
is heavy, but fragile. Take care that it doesn’t get banged around or
dropped.
Common Problems
• Battery gets hot: A battery that gets hot while charging has
become “resistive.” Current passes through it, but the battery will
not charge. The battery must be replaced.
• Battery recharges for a short time, even when full: This
means the battery is not accepting a charge. The capacity of the
battery has been diminished. The battery should be replaced.
• Battery will not charge: If you connect a room-temperature
battery and the charger will not start, the battery may be over-
discharged. When this happens, the charger does not even
recognize it has been connected to terminals. Leave the charger
connected to see if the battery will recover. If it will not accept a
charge within 24 hours, the battery should be replaced.
