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.
• Check and record electrolyte levels.
• Test and record specific gravity measurements.
• 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.
• Add distilled water as necessary.
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.
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 the specific usage. Following these recommendations will ensure
the batteries reach their rated capacity and keep them in good working order.
Following the break-in period a regular maintenance routine will be established
after 9-12 months of service.
Typically, 4000 & 4500 Series models will require maintenance every 30-60
days. Series 5000 batteries generally require maintenance every 60-90 days
as these models are designed with a higher electrolyte reserve allowing longer
periods between watering.
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.
