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 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 Flooded 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.
