Self Discharge; Electrolyte Liquid Level - Tomberlin 2010 E-Merge Maintenance Manual

entering the battery. Ensure the connecting terminals are tightly secured. When all terminals are
dried, apply the terminal protection oil to all the connecting terminals. Please refer to "self
discharge".
3. Maintain the electrolyte at normal liquid level. Please refer to "electrolyte liquid level".
4. The battery should be charged every day after it is used. Inspect the battery periodically to ensure
that the battery is fully charged. Please refer to "battery charging".
5. Tighten the hold-down gear. Please refer to "vibration damage".

Self discharge

The dirt on the battery may form weak battery passage, which may result in slow discharge of the battery
and therefore waste the precious electrical energy. To avoid self discharge, the battery should remain
clean all the time.
The temperature also has influences on the speed of self discharge by the battery. The higher the
temperature is, the quicker a set of battery is discharged. In hot regions, the battery should be inspected
more frequently. The battery should be stored in shady and cool places. Please refer to "storage of
battery".

NOTICE
• The battery acid exuded from the battery cover or hydrometer should be prevented from
dropping onto the front or rear body of the electric vehicle. Battery acid may result in
irremediable defect, and should be cleaned up immediately.
Water is filled only when the liquid level of electrolyte is lower than the height of positive and negative
plates. In case the liquid level of electrolyte is lower than the height of positive and negative plates,
please fill enough water to cover the plates before charging the battery. After charging, re-fill the water to
