MAINTENANCE SCHEDULE

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.

STORAGE

NOTE: When not in use, it is normal to expect 10-12% self-discharge per month

at 25ºC (77ºF) for Flooded models. This rate slows as ambient temperatures

decrease and increases at higher temperatures. Stored Series 4000 Flooded

batteries should be recharged every 3 months until the battery is put in service

to avoid sulfation buildup and possible freezing in cold temperatures.

Rolls Series 4500 & 5000 models with Advanced NAM carbon additive may see

an increased self-discharge rate of 20-25% per month at 25ºC (77ºF) when not

in use. A refresher charge may be necessary every 2-3 months.
