The above table shows an example of test data. The batteries used in this test are as follows:
Models DS 14DVB and 3615K: 2.0 Ah
Model DS 14DVA: 1.3 Ah
Model DW954K-2: 1.4 Ah
As actually measured values listed in the above table may vary depending on the sharpness of the drill bit,
workpiece hardness (particularly in wood materials), moisture content of wood, charging condition, operator skill,
etc. This data should be used as a comparative guide only.
