- Page 3 Safety information and do’s & do-not’s for Lead Acid Traction Battery Nominal Data information Nominal capacity C5 – See name plate Nominal voltage 2,0V x No of cell in the battery – See name plate Final discharge voltage 1.85V/Cell or specific gravity of electrolyte 1.170 at 30 Deg C. Nominal S.G.
- Page 4 Remove the battery compartment lid while charging. Charge batteries in ventilated place having exhaust fan. Contact Microtex for calculation of exhaust fan capacity. Use water to top up the battery. Refer specification provided in this manual for purity of water and acid.
- Page 5 Connect the battery with correct polarity (Refer figure 3 at the end of the manual) to a matching charger. Consult Microtex Energy Pvt Ltd for charger selection. A constant current charger is preferred for initial filling and charging. Charge with a current equal to 5 to 10 percent of C5 Ampere-hour rating of the battery.
- Page 6 Reading specific gravity of sulphuric acid and the correction for temperature: The acid gravity is read by the hydrometer and the temperature is read by a mercury-in-glass type thermometer. Avoid parallax error by keeping the acid level in the hydrometer in the same level of the eye. (Refer to figure 2 at the end of this manual).
- Page 7 Operational charge Microtex recommends charger which can fully charge the battery. Several methods of charging is available and one good method is using an IUIa-characteristic. In the first I-step the current recom- mended is 10 to 15 percent of the C5 Ah rating of the battery. The battery needs no current limitation but a soft start is recommended.
- Page 8 With the charger in switched off mode, connect the battery, ensuring correct polarity between the power plugs, that is positive to positive, negative to negative – (refer figure 3). Now, switch on the charger. During charging the temperature of the electrolyte rises by about 10°C, so charging should only begin if the electrolyte temperature is below 45°C so that it does not overshoot the maximum limit of 55 deg C.
- Page 9 If after the maintenance charge, the acid density is not uniform in all cells, add an equalizing charge (2.3). 3.1.4 Change of cell Only a trained person should be allowed to do cell replacement in a battery and conduct repair work. Contact Microtex if required.
- Page 10 3.1.5 Storage If batteries are taken out of service for a long period, they should be stored in the fully charged condi- tion in a dry, ventilated room. To ensure the battery is always ready for use, follow the charging method below: Provide Equalising charge as detailed in 2.3 at an interval of 8 weeks.
