If you want to live out your lumberjack fantasy, cordless chainsaws aren't for you.
However, if you need a saw for trimming and cutting small trees, they're just right.
They're the least powerful chainsaws, but they're the easiest to use.
Here are a few features to look for in a cordless chainsaw:
Lithium-ion batteries are the newest battery technology and offer better performance than Nickel-Cadmium (Ni-Cad) batteries. The main advantage is, they won't lose power as the battery loses its charge.
Performance of Ni-Cad batteries suffer as the battery dies. They also can take up to 12 hours to charge. Lithium-ion batteries can recharge in about an hour so you can get back to work.
Automatic Bar Oiler
Due to the constant metal-on-metal friction between the bar and chain of a chainsaw, the bar needs to be continually lubricated with oil. This allows the chain to run smoothly. Without it, chains break easily.
Look for a rechargeable chainsaw with an automatic bar oiler, which will constantly apply oil to the bar. Without one, you need to be vigilant about stopping to oil the bar, slowing you down.
