Cordless Wrenches Factors

That’s why you finally decided that you need a battery-powered impact wrench. The right influence is a great addition to any toolkit, while the wrong one can make your purchase useless. Either something that is too overpowered for what you need (as long as you have a variable torque, it’s not too bad, but at least it’s likely to be heavier and bigger than necessary) or under-powered (it’s much worse because it almost makes the tool useless) may be inappropriate. This article will cover what to look for in the battery. How much power you need, what to look for in the charger and what type of battery you need, and find more about cordless ratchet.

The most important aspect of the impact wrench is power. The whole point of impact is loosening these difficult to unscrew screws and nuts, and if you don’t have enough power, you’re basically left with an oversized pneumatic rattle. For cordless tools, the power supply comes from the battery and the key specification is voltage. The total voltage is the measurement of electricity. But more volts are not always better….. but it means that it is larger (if you compare two identical battery types), so if you are worried about the size of your battery, you may want to look for a battery with a lower voltage.

How often will you use your impact? And for how long? Do you remember the type that remembers that the batteries are charged? Having a charger that charges the batteries quickly can be very important for some people. Some high-end battery chargers have chargers that run in 15 minutes, while older chargers often take up to 3 hours per battery. If you’re going to use your batteries for a long time, or if you often have tight deadlines and you can’t afford to wait for the batteries to recharge as soon as they recharge, it’s important how quickly the batteries will be charged.

Finally, what type of battery is best? Nickel rechargeable batteries are older style, they are cheaper, but heavier and more massive. NiMH in particular will quickly lose its cold charge. Lithium ion batteries have a much higher energy density than nickel batteries, which means that you can have the same amount of power in a smaller package (or alternatively you can have more power in the same package size). However, lithium-ion batteries are the most expensive. Courses are such that if you buy batteries with a higher power (which I encourage, cheap are simply not worth it), they will be supplied with lithium-ion batteries, so it will probably not have an impact on what you buy, but just in case you look at older impacts, the difference between the batteries is important to know.

If you buy a new rechargeable impact wrench, remember how much power (and how many volts the battery has), what to look for in the charger and what is the difference between different types of batteries.
