Page 6: Specifications
SPECIFICATIONS CAPACITY The capacity of Hawker VRLA aircraft battery is rated in ampere-hours at the 1-hour rate (AhC ). An 18 ampere-hours ® battery will sustain an 18-ampere discharge for 1 hour down to a battery voltage of 20 volts. By conventional definition, the battery is deemed airworthy if it delivers its rated capacity for 48 minutes down to a voltage of 20 volts at +20°C i.e. -
Page 7: State Of Charge
STATE OF CHARGE The open circuit voltage of the battery prior to service can be used as an approximate guide to the state of charge of the battery. Figure 3 shows the relationship between open-circuit voltage and the state of charge of a new battery after 24 hours or more after recharge. -
Page 8: Condition Of Batteries On Receipt/Acceptance Checks
CONDITION OF BATTERIES ON RECEIPT /ACCEPTANCE CHECKS All batteries as dispatched are in a fully charged If the box is damaged from shipping, unpack the battery condition, the date of the latest charge being marked on to inspect for any damage. If damage to the battery is the outer packaging and on the battery instruction label. -
Page 9: Visual Inspection
VISUAL INSPECTION Visually inspect the exterior of the battery and receptacle for signs of damage, cracks or corrosion. If any defects are found, pack the battery in its original packaging and reject the battery in accordance with paragraph 13. VOLTAGE CHECKS 8.2.1 Measure the open circuit voltage (OCV). -

9.0 and continue with step 10.3. 10.2.3 If the OCV measures 20.0 volts or less refer to deep discharge decovery document number 9602-6298 (which is available from EnerSys Technical Support), as the battery is considered to be in a deeply discharged state. 10.3 Perform a capacity test per Section 12. -
Page 11: Service Period
10.3.2.1.2 If the result of the second capacity test is greater than 80% continue with step 10.4. 10.4 Record the capacity and date of test on the battery label. 10.5 Recharge battery per section 9. 10.6 Ensure the battery is clean and return the battery to service. 11. -
Page 12: Rejection Procedure
If the battery fails to attain a 48 minute run time (80% capacity) after two discharge tests and has been in service for less than two (2) years, recharge the battery in accordance with paragraph 9 and notify EnerSys or your distributor of failure. -
Page 13: Transportation
Hawker aircraft batteries consists of two 12-volt monoblocs encased in an outer case with removable lid. ® The two 12 volt monoblocs can be replaced; however they must be replaced in pairs supplied by EnerSys as part ® of a re-blocking kit. Lock nuts and internal battery connectors are supplied as part of the re-blocking kit and must be replaced at the same time. -
Page 14: Re-Blocking Procedure
18. RE-BLOCKING PROCEDURE Note! Prior to re-blocking the battery, check the integrity of the battery case, lid, connector and lid seal. Renew if damaged or showing signs of deterioration. When re-blocking a battery ensure that the correct re-blocking kit is used. i.e. denoted by ampere-hour rating. Warning! Short circuit currents will exceed 2000 amps;... -
