Great

Main highlights

•The 12V10A 120W battery discharge electric furnace wire is a fast detection tool for batteries. It is suitable for discharging various 12V lithium and lead acid batteries (voltage must be lower than 13V), and the voltmeter display screen will not show if the battery voltage is lower than 3.5V
•This product uses high-quality alloy resistance electric furnace wire, which generates heat more evenly. The outer layer of the electric furnace wire is a high-temperature resistant ceramic ring for maximum heat insulation. Warm reminder: Some ceramic rings may break during transportation, but it will not affect use
•When the electric furnace wire is working and generating heat, although it is protected by a high-temperature resistant and heat-insulating ceramic ring, the temperature will still be relatively high. Please do not touch it with your hands to prevent burns, and do not test it when the battery fluid is insufficient
•Please use the product on high temperature resistant and safe materials. There should be no flammable or explosive materials around. Please ensure that the product is used in a safe environment and pay attention to safety to prevent burns
•This product is intended as a repair tool for professionals. Please use it under the guidance of a professional
