Battery Life
The NiMH battery will last longer and perform better if allowed to completely discharge
before recharging. For maximum battery life, it is recommended that the NiMH battery be
completely discharged and recharged once every three months.
It is normal for NiMH batteries to self-discharge during storage (Figure 2-20) and to de-
grade to 80% of original capacity after 12 months of continuous use.
The battery can be charged and discharged 300 to 500 times, but it will eventually wear out.
The battery may need to be replaced when the operating time between charging is notice-
ably shorter than normal.
