What details do you need to pay attention to when charging and discharging a digital camera charger

Charging:

When choosing a charger, it is advisable to use a charger with a correct termination device(such as an anti-overcharge time device, a negative voltage difference(-dV) to cut off the charging and anti-overheat sensing device) to prevent the battery from overcharging and shorten its service life. In general, standard charging(in the range of 4 hours to 10 hours) can extend the battery's service life longer than ultra-fast charging(about ≤ 1 hour).

Discharge:

The depth of discharge is the main factor affecting the battery life. In general, the discharge cut-off voltage of the battery is 0.8 to 1.0 volts(after the cut-off discharge, the battery voltage will generally rebound to 1.1 V or more within a few minutes), which is acceptable. range.

If the battery is discharged at a high temperature, the service life of the battery will be shortened.

Battery charge time(= battery capacity / charging current x 120 %)

The charging time is generally increased by 10-60 % based on the large to small charging current to prepare for efficiency losses during charging.

The more suitable charging current for nickel-metal hydride batteries is 0.1 C-0 .5 C, and charging currents greater than 2C or less than 0.1 C may affect battery performance and shorten battery life.

If the battery is overcharged or over-discharged, the performance of the battery will be reduced and the performance will be poor.

Nickel hydride batteries:

1, can not deep discharge, it is forbidden to use a light bulb or resistance to discharge the battery to completely no electricity!

It is forbidden to recharge newly charged batteries by force

Batteries that can not be stored for long periods of time, should be recharged and should be recharged every three months
