Which tools require a battery charger?
Many power tools run on batteries: drills, electric screwdrivers, hedge trimmers, edge-trimmers, circular saws... Below a certain level of power consumption, battery-powered tools are common.
What are the important factors for choosing your charger?
- Compatibility of battery terminals with charger terminals;
- Output voltage and current;
- Inclusion of a charge indicator;
- Versatility (universal battery chargers);
- Charge time;
- Battery types accepted - Lithium-Ion (Li-Ion), Nickel Cadmium (Ni-Cd) or Nickel Metal Hydride (Ni-MH);
- Power supply - 3-tine plug for 240V mains supply or car cigarette lighter socket for building sites without electricity.
Charge time is also dependent on current characteristics - with a powerful battery charger, a 1.5Ah Lithium-Ion battery will recharge in 30 minutes, 3Ah in 60 minutes and 4Ah in 80 mins. The greater the amp-hour (Ah) value, the more charge the battery can store, hence the proportional charge times given.
Some top tips for choosing
Given the widespread availability of battery-operated power tools and the different terminals specific to each manufacturer, your choice of battery charger will crucially depend on these two criteria: brand and type of tool(s) to be charged.
And of course, make sure you the voltage and amperage match between battery and charger!
