Charge Battery Safety Precautions
Never charge a battery without first reviewing the manufacturers instructions for the charger. In addition to the manufacturer's instructions, follow these safety precautions:
WARNING
Explosive hydrogen gas, which escapes during charging, could cause death or serious injury. Charge battery in a well-ventilated area. Keep open flames, electrical sparks and smoking materials away from battery at all times. KEEP BATTERIES AWAY FROM CHILDREN. (00065a)
  • Always wear proper eye, face and hand protection.
  • Always charge batteries in a well-ventilated area.
  • Turn the charger OFF before connecting the leads to the battery to avoid dangerous sparks.
  • Never try to charge a visibly damaged or frozen battery.
  • Connect the charger leads to the battery; red positive (+) lead to the positive (+) terminal and black negative (-) lead to the negative (-) terminal. If the battery is still in the vehicle, connect the negative lead to the chassis ground. Be sure that the ignition and all electrical accessories are turned off.
  • Make sure that the charger leads to the battery are not broken, frayed or loose.
  • If the battery becomes hot, or if violent gassing or spewing of electrolyte occurs, turn off the charger temporarily.
  • Always turn the charger "OFF" before removing charger leads from the battery to avoid dangerous sparks.
WARNING
Unplug or turn OFF battery charger before connecting charger cables to battery. Connecting cables with charger ON can cause a spark and battery explosion, which could result in death or serious injury. (00066a)
NOTICE
If battery releases an excessive amount of gas during charging, decrease the charging rate. Overheating can result in plate distortion, internal shorting, drying out or damage. (00413b)
Figure 4. Measuring Specific Gravity of Electrolyte with Hydrometer
NOTE
  • A trickle charger or CHRISTIE charger with a 1 amp charging rate (or less) may be used. However, it will take at least 24 hours for the 100% initial charge with these types of chargers.
  • The recommended alternative is a variable/tapered rate charger with a maximum charging rate of 2 to 8 amps. With this type of charger, the initial charging rate should be the maximum charging rate for the particular charger (ie. 2 to 8 amps). However, over a period of time, possibly as little as 1 to 2 hours, the charging rate will taper off to near 0 amps. At this point, the battery has probably attained a charging voltage of 14 volts or greater. Continue charging the battery for at least the remainder of the 12 hours total charge time, even though the battery electrolyte has probably attained its proper specific gravity. This additional charging time is necessary to "set" the cell plates in a low-maintenance battery.
Charge Battery Procedure
NOTICE
Remove battery from motorcycle before charging. Electrolyte leakage will damage motorcycle parts. (00213a)
1.
Follow instructions in applicable Service Manual to remove the battery from the motorcycle.
2.
Place the battery on a level service.
3.
Refer to Table 1. Set battery charger to the recommended charging rate.
WARNING
Unplug or turn OFF battery charger before connecting charger cables to battery. Connecting cables with charger ON can cause a spark and battery explosion, which could result in death or serious injury. (00066a)
NOTICE
Do not reverse the charger connections described in the following steps or the charging system of the motorcycle could be damaged. (00214a)
4.
Connect the red battery charger lead to the positive (+) battery terminal.
5.
Connect the black charger lead to the negative (-) terminal of the battery.
6.
See Figure 4. Charge battery until specific gravity of electrolyte increases to 1.260-1.270 at 80° F (27° C). Measure with HYDROMETER (Part No. HD-96910-35).
NOTE
  • Cell variance must not exceed 0.010 specific gravity.
  • If recommended charging time has elapsed but specific gravity is still below 1.270 at 80° F (27° C), continue charging until desired specific gravity is attained.
  • When using a syringe hydrometer, read electrolyte level at bottom of meniscus (curved upper surface of fluid).
  • Specific gravity changes with temperature differences. When the temperature increases, specific gravity of a typical fluid decreases, and vise versa. If electrolyte temperature in battery is not 80° F (27° C), use the following formula to compute temperature-corrected specific gravity: For each 10° F (5.5° C) above 80° F (27° C), add 0.004 to actual specific gravity reading. For each 10° F (5.5° C) below 80° F (27° C), subtract 0.004 from actual specific gravity reading. For example: Electrolyte temperature 100° F (38° C) Hydrometer reading 1.272 Adjustment for temperature + 0.008 Corrected specific gravity 1.280
7.
After initial charge, gently tap battery to dislodge air bubbles from cell plates.
NOTE
If electrolyte level has fallen, refill battery with distilled water to the upper level and charge an additional 1 - 2 hours.
8.
After the battery is fully charged, disconnect the black lead to the negative (-) terminal of the battery.
9.
Disconnect the red charger lead from the (+) terminal of the battery.
10.
