BATTERIES Battery Storage BATTERY NO. DISCHARGE VOLTAGE 1 2 3 4 5 6 4.08* 5.50 5.80 5.36 5.57 5.56 *After a discharge test which lasted 65 minutes, battery No. 1 is clearly shown to be the problem. Battery No. 4 should be watched a little more closely but appears to be functioning properly. Battery No. 1 should be replaced with a battery that has about the same age and usage as the other batteries. Example 2 Vehicle No. 70 was also suspected of having a faulty battery due to its performance. The battery charger test showed 7.0 amps after a full charge. After confirming there were no problems with the electrical system, charger or brakes, the on-charge voltage was recorded as follows: BATTERY NO. ON-CHARGE VOLTAGE 1 2 3 4 5 6 7.86 7.33* 7.90 7.93 7.91 7.75 *Battery No. 2 was clearly identified as the problem. After checking the No. 2 battery with a hydrometer, it was discovered the negative post cell was completely dead. Battery No. 2 should be replaced with a battery that has the same age and usage as the other batteries. BATTERY STORAGE Read DANGER and WARNING on page 13-1. When storing batteries during the off-season or when maintaining a replacement stock, follow these guidelines to keep batteries in good condition. 1. Keep the batteries clean and free of corrosion as outlined in the Battery Care section. 2. Batteries should be wired in series so they can be connected to the charger. Batteries that are in vehicles for winter storage can be left in the vehicles. 3. Fully charge the batteries prior to storage. 4. Store in a cool area. The colder the area in which the batteries are stored, the less the batteries will self-discharge. Batteries stored at 0°F will discharge very little over a four-month period. Batteries stored at 80°F will have to be recharged every few weeks. 5. Check the state of charge periodically. Batteries that are discharged and left in a cold environment can freeze and crack. If the specific gravity drops below 1.220, the batteries should be recharged. See the following chart. SPECIFIC GRAVITY FREEZING POINT 1.260 -70°F 1.230 -39°F 1.200 -16°F 1.170 -2°F 1.110 +17°F 6. The frequency of recharging required will depend on the temperature of the storage area, but it is recommended the batteries be monitored for state of charge every month. Also, if the storage area is unheated in a cold climate and recharge is required, it is recommended the area be heated to at least 60°F prior to charge. Batteries do not charge effectively in cold temperatures for the same reasons they do not discharge as rapidly in cold temperatures. 1998/1999 V-Glide 36-Volt Vehicle Maintenance and Service Supplement Page 13-13 13
