Battery care and runtime
Attached time costs charge, even when you are not drilling.
Two loads
The 20 V 6 Ah lithium-ion pack powers both the vacuum pump and the rotary hammer. The pump draws whenever the tool is attached — including while you are measuring, marking or talking.
Practical habits
- Detach when you are not drilling rather than leaving the tool anchored across a break.
- Carry a spare pack for a full day of anchor work.
- Charge overnight rather than opportunistically mid-task.
Temperature
Cold packs deliver less current and less runtime. Keep spares warm in winter.
Let hot packs cool before charging.
Storage
Store part-charged, in moderate temperatures, out of the vehicle in extreme weather.
Questions about this
Why does the battery drain when I am not drilling?
Because the vacuum pump runs whenever the tool is attached. Idle attached time costs charge, so detach during breaks rather than leaving the tool anchored.
Does cold weather affect it?
Yes, on two fronts: cold packs deliver less current and less runtime, and a cold sealing pad is stiffer and conforms less well.
