SERVICE RELEASE N9

NATURE OF RELEASE: Putting batteries into service MODELS AFFECTED: Al 1 Commando PARTS AFFECTED: Lucas Batteries DISTRIBUTION: Worldwide EXPLANATION: Experience has shown that a relatively large number of batteries are damaged by incorrect preparation or discarded as un-serviceable due to sulphating in the dry charged condition in shipment, whilst perfectly serviceable if given a suitable initial charge.   ACTION: With batteries and acid at . a temperature of between 60 degrees F and 100 degrees F fill with acid S. G. 1.260 (temperate) or 1.210 (tropical). Read electrolyte temperature a few seconds after filling by inserting a thermometer into each individual cell in turn. After standing for 20 minutes individual cell temperatures are again read and the temperature. rises noted. The open-circuit voltage of the battery is then read using a good grade voltmeter. If the temperature rise in any one cell or cells is not greater than 10 degree F and the open-circuit voltages not below 12.4 then the battery is ready for service. If these limits are exceeded the battery should be charged at 0.8 amps until the on-charge voltage remains constant over three successive hourly readings and all cells are gassing freely. Batteries which are older than 12 months before being filled for service should be charged at 0.4 amps until on-charge voltage remains constant for three successive hourly readings and all cells are gassing freely. On machines shipped overseas, having dry-charged bettkries and no sealing plug at the end of the manifold, the battery must be dealt with automatically as in paragraph above.
