1.1 Preparation data
Matters needing attention in operation
* Note
1. The battery can be charged and discharged over again. If the battery is unused after discharge, the service life
will shorten and the performance will degrade. Generally, performance of the battery used for 2 or 3 years will
degrade. Such battery
（
capacity declined
）
may restore its voltage after charging but the voltage will drop off rapidly
when loaded.
2.Surcharge of battery
：
generally surcharge can be observed from the battery proper. If the battery is cut short
inside, no voltage can be tested at the terminal of the battery or the voltage is very low. Invalidation of the
regulator
：
the battery will have too high voltage, which may shorten its service life.
3. Long rest of the battery will result in self discharge and the electric capacity will reduce, therefore, it must be
charged every 3 months.
4. Inspect the charging system in accordance with the order stipulated in the fault diagnosis table.
5. If there is electric current passes through an electrical unit, do not disassemble the connector, otherwise,
overtension will occur which can damage the electronic parts inside the voltage regulator. The main switch must
be pushed to "off" before any operation.
6. Maintenance free
（
dry charged type
）
battery does not need inspection, replenish of electrolyte solution or
distilled water.
7. Inspect the entire power load.
8. Emergency charging cannot be used except in contingency situations.
9.In emergency charging of the battery
，
it must be unloaded from the motorcycle before charging.
10. Please do not use liquid type battery when exchanging batterys.
11. A voltage meter must be used when inspecting the charging conditions.
