For the first 12 months of usage, the following tests should be completed:
MONTHLY
• Measure and record resting/loaded voltage
• Check electrolyte levels and top up with distilled water as necessary
• Test and record specific gravity measurements in Float charge
• Record ambient temperature where the batteries are installed
• Inspect to ensure temperature sensor is securely attached
• Inspect cell integrity for corrosion at terminal, connection, racks or cabinets
• Check battery monitoring equipment to verify operation
QUARTERLY
• Test Ventilation
• Check terminals/connections, remove corrosion and properly re-torque
• 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
Deep cycle batteries will increase in capacity during the initial break-in period of 60-90 cycles. Adjustments to charging parameters may be necessary during this time. Battery performance, charging and maintenance requirements will depend on usage. Following the break-in period, a regular maintenance routine will be established after 9-12 months of service.
Following these recommendations will ensure the batteries reach their rated capacity and operate in good working order.
