There are two types of circular saws: corded or cordless. Thanks to the improved battery technology, cordless circular saws are as powerful as corded models, but more convenient. Manufacturers also design and produce cordless versions. When we choose them, just remember the higher voltage of its motor and the large capacity of its rechargeable batteries means it is more powerful.
Most early versions only supported a 3.5″ blade because their voltage was as low as 9.6v and the Ni-Cads batteries have a small capacity. But now, as Lithium-Ion batteries are used widely, the latest circular saws become more powerful and can support a 6.5″ blade. The Lithium-Ion batteries have a larger capacity and are able to be charged more quickly, which can help you quickly get back on the job without waiting for a long charging time. They have abilities to compete with corded versions. Corded models use 7-1/5 inch blade – a little bigger than 6-1/2″ bladed used on corded models, but the performance is similar to each other. You can use a cordless model for construction and it is capable of cutting plywood and standard dimensional lumber as well.
If you are looking for the best cordless circular saw, you can check our list below. When we chose them, we focused on their comfort, weight, convenience, prices, ratings, as well as customer reviews. They are the ones you can rely on. One thing you need to pay attention is that not everyone comes with 2 batteries. After all, each Li-Ion battery costs over $100. When you decide buy one, pay attention to this.

At last, as I said at the opening, the alternative battery is very important. Some of them don’t come with an alternative battery that you may cost over $100 to buy one. Therefore, if the models come with 2 batteries and the whole price is also modest, it is a nice choice.
