Red plastic battery brush
The product is a battery brush, and the brush head is made of steel wire, which is super hard. A single brush head, specially cleaned the oxidized battery pile head, very convenient and durable to use! The difference between before and after use is very large.
After a long period of use, the battery will not only accumulate thick dust, but also the acidic electrolyte inside the battery will overflow due to heat during use, corroding the ends of the electrode.
When both ends of the battery are blocked by these substances, it is difficult for the battery to perform its normal function. The worsening battery will make your car start slower and slower.
If the car and the battery are in good contact, the connection is stable. The poles on both ends of the battery should be clean, clean and metallic. Why do you want to be metallic? If your battery has been cross-lined, the crossover cable clamp will leave a scratch on your battery pole and metal will be exposed at the scratch. Although the cross-line startup will leave an indelible scar on your battery, you will inadvertently discover that it is with these scratches that the battery functions much better than before.
