Can this battery be used for dw944 cordless 3/8 Ver drill
The DW9062 should be compatible with all 9.6V DeWalt tools except for Univolt series. However, I would recommend to research more about its compatibility with the DW944 drill and its original battery, DW9048. I didn't find any reference in regards to your model #.
Update: I just checked with the manufacturer, and they say it is fully compatible.
How long will it last and be rechargeable?
You can calculate the number of hours your power tool will last on a single battery charge using the following formula:
9.6 * 2 / X, where X is the tool's power consumption in Watts.
