For more than 100 years of practice, the Japanese manufacturer Hitachi has learned how to make high-quality power tools. His popular models top quality product ratings. It was the widely used parameters of devices at a favorable price with a peculiar design that caused the popularity of the models.

About the best parameters

In an effort to diversify the range of drills, screwdrivers, Hitachi produces various tools. However, some types of models, due to their "backward" characteristics, were not included in this rating. This applies to batteryless, wired models. And models with nickel batteries.

Because it is wrong to hang a “best” tag on a model if its technical characteristics are much worse than the one that is really better. Lithium batteries are significantly superior in all characteristics, negating the price difference. Not to mention the wired models.

Chargers have become so simplified that their absence has almost no effect on the price of the device, but the possibilities and ease of use are somewhat reduced for models without batteries. Therefore, they are not covered in this article. Although it makes sense to purchase this type of screwdriver because of its simplicity. But it won't be the best.

Why Lithium Batteries Are Better

There are a large number of batteries, but the people have developed an idea mainly of lead-acid. True, now, mobile phones have changed the concept of batteries and they use only lithium. This is facilitated by a number of quality characteristics.

Alkaline batteries, or they are also called nickel-cadmium, are 2 to 4 times more effective than acid ones, but more expensive. And if you assemble a screwdriver on an acid battery, you get a cumbersome and heavy structure, the charge of which will only last for a couple of minutes. Therefore, nickel-cadmium (Ni-Cd) batteries have always been used in portable designs. Later, lithium were developed.

The main disadvantages of nickel batteries in comparison with lithium ones are the need for their complete discharge, especially before storage, as well as the parasitic "memory effect". As a result, the screwdriver must be constantly fully discharged after work, and charged before work.

But the already half-discharged battery cannot completely screw the screw into the durable material. You have to tinker with it, sometimes for several minutes, to completely plant the battery. And then wait for the battery to be fully charged. If you immediately start recharging, the "memory effect" will appear, and the battery will lose voltage at half the discharge.

If at this stage the battery is not "cured", then it can then be discarded altogether, which, by the way, many do. A lithium battery is completely free from these disadvantages. And if a tight screw is caught in the process of work, then 3 minutes of recharging will fix the problem without harming the not cheap battery.

We bring to the attention of our readers a description of really excellent screwdrivers, one of the best manufacturers - Hitachi.
