Battery General Information

^ For best results, use an automatic taper-rate battery charger with a voltage capability of 16 volts.




^ A battery showing a green dot in the hydrometer (A) does not need to be charged unless the J 42000 battery tester has shown that the battery needs to be charged.
^ A battery showing a dark dot in the hydrometer (B) should be charged unless the J 42000 battery tester has indicated no charge is needed.
^ Do not charge a battery when the built in hydrometer is clear or yellow in the center (C). Tap the hydrometer lightly in order to dislodge any air bubbles. The bubbles may cause a false indication. If the hydrometer is still clear or yellow, replace the battery.
^ The charging area should be well ventilated.
^ Do not charge a battery that appears to be frozen; allow the battery to warm to room temperature and test it before charging.
