If my original power tool battery is an NiCD battery, can I use a different chemistry battery?
☆ That would depend on both your charger and power tool. A lot of chargers will charge NiMH batteries and a few others will charge Li-Ion. However, even if your charger will do this, your power tool might not. It is best in these situations, to check your user manual or contact the manufacturer to find out the technical specs of your model.
How long will my power tool last with a fresh charge?
☆ That question can only be answered by how you use your power tool. For example, when using a drill your usage time can vary based on the speed you use. Drilling into steel will use more power than drilling into wood or drywall.
☆ Here are some formulas to help give you an idea of how long the battery will last.
☆ Amp hours = number of amps x number of hours
☆ Amp hours / number of amps = number of hours
How can I prolong the life of my HITACHI WH 9DM batteries?
☆ There are several things you can do to help extend the life of your battery. First, store it separate from the tool to which it belongs. Do not leave it in the charger when it is fully charged. Second, keep it in a place that has a fairly consistent temperature. Finally, if dealing with Nickel based batteries, make sure that the battery is fully discharged before recharging it.
