Thread: DeWalt 110Volt cordless tools

Provided the new and existing gear use the same battery chemistry, voltage, and the batteries have the same nominal capacities and connector layout etc, you should have no hassles mixing and matching.

Depending on the nominal charge time for the battery/charger combinations, you may need a hefty transformer.

I am running a lot of 110 V charger equipted Mak 18V Lithium gear, and the chargers are rated to charge a flat 3AH battery pack in 22minutes. The charger draws about 2.2A at 110V to do this so the minimum spec for the step down transformer is in the order of 250 VA, 300 would be better. I have a 1200VA unit and can run multiple chargers.

An alternative, particularly if you need to consider field charging is a 110V 300 to 400 VA inverter running from a car battery. I have an 800VA one I got from US ebay for about $55AU delivered when I bought the gear. Works well for running 2 Mak chargers, but is a bit hard on the batteries running 2 up.

Mak also offer a slower charger for their kit, about 1 hour for a full charge. I don't know if that is a possible option for DW, but it would make the transformer smaller and cheaper.

Thanks for the reply, malb.
Do you know if it is possible to charge the batteries which come for US, on an Aussie 240V charger. (assuming terminals, voltages etc match)?

I can't say for certain but you should be able to plug the American batteries into the Aussie charger. Charging voltages and currents will be the same.

From my first post

"Provided the new and existing gear use the same battery chemistry, voltage, and the batteries have the same nominal capacities and connector layout etc, you should have no hassles mixing and matching."

This applies to charging as well as operating tools etc.

I have a mix of Dewalt 18v batteries and tools from both US and here. No worries charging them in your 240v charger, the only exception is the lithium batteries won't charge in the older style chargers.

hi tm.

i have bought heaps of makita lithium-ion cordless tools from ebay in the u.s.

i already have australian chargers so i throw the u.s. charger in the bin.

the batteries are the exact same, whether the charger is 110 volt or 240 volt.

i cant say for sure that dewalt will work. but i assume that they will work.

regards, justin.

Thanks gents,
that is exactly the info I was after.
cheers

I have also used batteries bought in Australia on a 110v charger ( my 240v charger broke) - with no worries at all for same battery type.
