Methodology For Determining The Malfunction of The Screwdriver Battery
Quick Battery Check with A Multimeter
- Since the batteries have a serial connection circuit, it is important to know that when the batteries are in a charged state, their voltage tested with a multimeter should be identical. To correctly identify the faulty link, you should switch the tester to the DC current change mode and measure each battery (bank) in the system. If ni cd batteries are used in your case, then the nominal volta…
Load Testing
- This method involves the use of several light bulbs or small electric motors that are connected to each power element in a screwdriver battery system. First, the entire battery is fully recharged. Then, one 3-4 V bulb or low-power “motor” is connected to each “bank”. The method allows without measuring devices to identify inoperative elements in th...
“Memory Effect”, and What to Do with It?
- If we are talking about ni cd batteries, then for them there is such a thing as “memory effect”. This "painful symptom" is defined quite simply. When the battery quickly discharges after a full charge cycle, and after a short pause continues to function again, this is the correct diagnosis, which can be cured with proper dexterity. What needs to be done to heal the “memory effect"? First, the bat…
What Additional Battery Recovery Methods For Screwdrivers Exist?
- It should be noted right away that not all batteries are subject to the ability to recover. In particular, the “banks” with the typical ni cd insignia can be reanimated with the best success. These batteries are now equipped with most of the typical models of screwdrivers. Of course, in the tool market you can find Makita or hitachi or bosch screwdrivers whose battery is built on a l…
