If you own any type of Hitachi battery-powered tool, then you know that it is important to know when the battery is charged. This is essential for proper tool maintenance and for the longevity of the battery and the tool. Fortunately, it is relatively easy to tell when a Hitachi battery is charged and ready for use.
Understand the Charging Process
The first step to understanding when your Hitachi battery is charged is to understand the charging process. When you plug your battery into the charger, a circuit is activated. The charger then sends a current through the circuit, which charges the battery. The charger will continue to send this current until the battery is fully charged. Depending on the model of battery and the charger, this process could take anywhere from a few minutes to a few hours.
Look for the Indicator Light
Once the battery is fully charged, the charger will shut off the current and an indicator light will come on. This light will usually be green or blue, depending on the model. It is important to note that if the light is red, then the battery is not fully charged and should remain in the charger until the light turns green or blue.
Unplug the Battery from the Charger
Once the indicator light is green or blue, you can unplug the battery from the charger. You should always wait for the indicator light to come on before unplugging the battery. This will ensure that the battery is fully charged and ready for use. It is also important to note that you should never leave the battery in the charger for too long, as this can cause damage to the battery.
Take Advantage of Smart Chargers
For those with newer Hitachi battery models, you may have access to a "smart charger." These chargers are specially designed to detect when the battery is fully charged and will shut off the current automatically. This ensures that the battery is never overcharged, which can damage it. If you have a smart charger, then you do not need to worry about the indicator light, as the charger will take care of charging the battery automatically.
