The 88F mark on the lithium battery of the electric wrench is the model of the battery produced by the manufacturer. F is the battery attribute, which means lithium iron sulfide, iron sulfide positive and lithium negative. The property types of lithium batteries are represented by the letters BCEFG, and lithium batteries include lithium batteries, lithium ion batteries, lithium ion polymer batteries, etc.
In general, below are some small numbers, including voltage and capacity. For example: 15-21V. Refers to available output power from 15V to 21V.
Voltage and current specifications of the 88F are 88 volts/9000 mAh. Its specifications are the same as 88V and there is no difference.
Detailed information:
1. Don't overloaddon't. Late at night, the load on the power grid is very light and the voltage rises very high. It is easy to exceed the full shutdown voltage set by the charger, and the battery will continue to be charged, which can easily cause overcharging late at night. , the charger must be unplugged.
2. Don't overload. Lithium batteries have no memory effect and can be recharged at any time. Do not discharge with high current. In places with steep slopes, it is better to use pedal assist to avoid excessive battery current, which will affect battery life.
3. Do not charge until the battery is completely exhausted. This can easily damage the battery due to over-discharge.
4. Avoid exceeding the load specified in the instruction manual.
The battery of the electric key is activated by charging the celllule the battery directly with a constant current and constant voltage source.
The activation method of the electric key is to use a constant current and constant voltage source to directly charge the battery (there is a lithium battery after removing the plate protection without dismantling the battery); , Find a way to tear a small opening on the label paper. After tearing it off, there should be an outer foil wrapper. Use the black test lead of the constant current source to face the negative input terminal of the protection board. The red test pen is loaded against the aluminum shell. When the voltage exceeds 3.0V, it stops and the electric key is activated.
An electric wrench refers to a power tool for tightening and loosening bolts and nuts. It is a tool for tightening high strength boltsnce.
