If you stay at anchor (as I do most of the time) you might find it
inconvenient to have to run the engine for the time required to charge
the drillbattery. So if you prefer to run the drill on the drill
batteries, a 9.8V drill that will charge directly from the boat
battery might be more practical.

I prefer to run the drill directly form the boatbattery with a wire.
If you are sitting at anchor and has the time, you can carve a
dummy-battery with wire so you can switch between boatbattery and
drillbattery. You could even ad some metal to the dummy to make the
balance of the drill right.

I think that you can read the charge voltage on the charge-box that
comes with the drill.

I think any 12V drill will run on the boatbattery, but if you want
to
charge maybe a 9V would be better.


The same charging system that charges the boat's 12 volt batteries
will have no
problem charging the 12 volt batteries for the drill.

The voltage on a boat system generally varies from 14.? to 11.5V,
depending on whether you are charging with a efficient charger or
you
are using a half charged battery. A cheap measuring box will tell
you
what your voltages are when you run your engine, charge with
shorepower or just take power from the battery.

Boats-r-US has a Seafit 12v drill on sale. Is there a 12v drill
which will
run and/or charge off your boat batteries?
