BATTERY CHASSIS ELECTRICAL 54A-9 BATTERY SERVICE SPECIFICATION M1541000301031 Item Standard value Battery electrolyte specific gravity 1.220 − 1.290 (electrolyte temperature 20°C) ON-VEHICLE SERVICE FLUID LEVEL AND SPECIFIC GRAVITY M1541000900364 CAUTION • If the battery is used with the electrolyte level below the LOWER LEVEL indicator, there is • AC102027 OK AB Thermometer Specific If too much water is added to make the level 1. Check that the battery electrolyte level is between the UPPER LEVEL and LOWER LEVEL 2. Use a specific gravity meter and a thermometer to measure the specific gravity. Standard value: 1.220 − 1.290 (electrolyte temperature 20 °C) The specific gravity of the battery electrolyte °C can be calculated using the following for- mula. Use the converted value to judge whether the D 20 = (t − 20) × 0.0007 + Dt D 20 : Specific gravity converted to a value for electrolyte temperature of 20 °C t: Electrolyte temperature at the time of Dt: Actual specific gravity CHARGING M1541001102185 CAUTION • The battery plugs should be removed during charging. • The battery electrolyte level may rise and overflow from the battery during charging. • Explosions may occur if the battery is brought close to naked flames during charg- • Be careful to avoid tasks that might produce sparks or other danger while the battery is • After charging is complete, reinstall the bat- tery plugs, pour water over the battery to • Charge the battery in a well-ventilated loca- tion. • Do not let the battery electrolyte temperature rise above approximately 45 °C (approximately 55 °C during rapid charging). 1. Remove the battery from the vehicle. 2. The normal charging current is a value in amperes which is 1/10th of the battery capacity. If |
