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.
