Batteries should be kept clean at all times. If installed or stored in a dirty location, regular cleaning should be performed. Before doing so, assure that all the vent caps are tightly fastened. Using a solution of water and baking soda (100g per litre), gently wipe the battery and terminals with a damp sponge, then rinse with water.

TERMINALS

Inspection of battery terminal connections is also important. Loose connections may result in ignition of hydrogen gases or cause a short, melting the terminals. It is important to inspect, disconnect, clean and properly torque these connections on a regular basis.

MAINTENANCE SCHEDULE

For the first 6-12 months of a systems life you should check the following things:
MONTHLY
• Measure and record resting/loaded voltage.
• Record ambient temperature where the batteries are installed.
• Inspect cell integrity for corrosion at terminal, connection, racks or cabinets.
• Check battery monitoring equipment to verify operation.

QUARTERLY

• Test Ventilation.
• Check for high resistive connections.
• Check cabling for broken or frayed cables.
• Verify Charge Output, Bulk/Absorption voltage of Inverter/Charge Controller.
• Check cells for cracks or indication of a possible leak.
• Check Ground connections.

STORAGE

NOTE: It is normal to expect 1% self discharge per day when not in use, under
normal temperature conditions. Stored batteries should be recharged every 3
months until battery is put in service to avoid sulfation and possible freezing
in cold temperatures.
