Some of our customers are confused to choose the right battery for themselves. Here, we'd like to share our ideas.
You need to know the battery part number and the fit model of your machine. Only when these are both advise on the item description that the battery could meet your need.
You also need to know the battery type of your battery and battery charger. For example, when you want to buy a Ni-MH power tool battery, but your battery charger is only for Ni-Cd battery. It will be a waste of money since the Ni-CD charger is not fit for the Ni-MH battery.
You need to take a look at the dimension too. Some of the high capacity battery will be bigger than the low capacity OEM battery. Hope these tips may help!
