The outward appearance of these two batteries is similar, but the operating characteristics are very different. The Club Car electric vehicle battery is a deep-cycle battery, and the automotive battery is a “starting, lighting and ignition” (SLI) battery. They should never be substituted for one another.

Contaminants on dirty batteries can provide a path for a small current draw that can slowly discharge batter- ies, thus wasting valuable energy. To prevent self-discharge, batteries should always be kept clean. 2006 IQ Plus System Electric Vehicle Maintenance and Service Supplement Page 14-3...
For best results, use a battery watering gun to add water to batteries. Check the electrolyte level more frequently in hot weather or when batteries are old. Page 14-4 2006 IQ Plus System Electric Vehicle Maintenance and Service Supplement...
IQ Plus vehicles will damage the batteries. The charger supplied with the Club Car electric vehicle resolves the most common problems associated with battery charging. Undercharging and overcharging are prevented provided the charger is allowed to shut off by itself.
The deeper the discharge, the harder it is on the batteries. For this reason, it is recommended that Club Car electric vehicle batteries be charged after each use (pro- vided the charge cycle will not be interrupted and the charger will be allowed to shut off automatically). Placing the batteries on charge after each use reduces the depth of discharge and prolongs battery life.
If discharge time is 60 minutes or If discharge time is less than 60 minutes, replace all batteries below 5.0 V. more, problem is not with the batteries. Figure 14-5 Battery Troubleshooting Chart 2006 IQ Plus System Electric Vehicle Maintenance and Service Supplement Page 14-7...

If the difference between the cells is 0.020 or more, the low cell should be suspected. It may require a catch- up charge or it may be a weak cell. When the variations between cells reach 0.050 or more, the battery with the low cell should be replaced. 2006 IQ Plus System Electric Vehicle Maintenance and Service Supplement Page 14-9...
