BATTERY CHECK
| WARNING | Battery posts, terminals and related accessories contain lead and lead compounds. WASH HANDS AFTER HANDLING. |
BATTERY CHARGING
| WARNING | When batteries are being charged, an explosive gas forms beneath the cover of each cell. Do not smoke near batteries on charge or which have recently been charged. Do not break live circuits at the terminals of the batteries on charge. A spark will occur where the live circuit is broken. Keep all open flames away from the battery. |
Battery electrolyte temperature may temporarily be allowed to rise to 55 °C (131 °F). Increase of electrolyte temperature above 55 °C (131 °F) is harmful to the battery, causing deformation of battery cell, decrease in life of battery, etc.
CHARGE RATE
Recommended rate and time for fully discharged condition (flat discharged) is shown in the table below. When the specific gravity of electrolyte keeps 1.22 to 1.29 for more than one hour, charging should be stopped.
| Item | Charging time |
|---|---|
| 75D23L | |
| Slow charging | 5 amps 11 hours |
| 10 amps 6 hours | |
| Fast charging | 20 amps 3 hours |
| 30 amps 2 hours |

CURRENT SENSOR RESISTANCE VALUE
Use the circuit tester to measure the resistance value between battery current sensor connector terminals.
| Terminal No. (positive terminal - negative terminal) | Resistance (kohms) |
|---|---|
| 1 - 3 | 3 - 10 |
| 1 - 4 | Less than 0.5 |
| 3 - 4 | 3 - 10 |

TEMPERATURE SENSOR RESISTANCE VALUE
Using the circuit tester, measure the resistance value between the battery current sensor connector terminal No. 2 and No. 3.
| Temperature (°C) | Resistance (kohms) |
|---|---|
| 0 | 4.5 - 7.2 |
| 25 | 1.6 - 2.5 |
| 40 | 0.96 - 1.40 |
