Great product good price. Fit's well and has a reasonable life and functions great.
Ordered this as I bought the appropriate drill from Aldi (which, to no surprise, didn't come with the battery) and I've already made good use of this since having it arrive.
So useful and charged the battery in only 45mins which is quick and useful.
Fast delivery. The charger fully charged the battery in a short period of time.
This is a good charger. One happy husband.
Perfect for the Ferrex chainsaw. Quickly delivered.
