Portable lithium-ion jump-starter pack emergencies and override mode dangers¶

Compact handheld 12-volt lithium-ion jump-starter packs (LiCoO2 kapena LiFePO4 battery boosters) have built-in smart-relay safety boxes mounted on their short jumper cables that automatically check for correct polarity before allowing current to flow. However, misusing their manual "Boost / Override" button creates a severe fire and explosion hazard:

1. Why smart jump packs refuse to click ON when attached to a completely flat 0-volt battery: A smart lithium jump pack relies on sensing at least 1.5V ku 3.0V from the vehicle's dead battery to verify that the red clamp is on + and the black clamp is on -. If your car battery is drained completely down to 0.0V, the smart relay cannot detect polarity and refuses to energize the clamps.
2. The danger of pressing the manual "Override / Force Boost" button: When you press and hold the manual Override / Boost button on a lithium jump pack for 3 seconds, all reverse-polarity, short-circuit, and spark-proof protections are completely disabled, energizing the clamps directly from the high-discharge lithium cells. If you accidentally have the clamps reversed on a dark engine bay when you press Override, the lithium pack itself will instantly short-circuit, swell into thermal runaway, and vent a jet of 700-degree-Celsius (1,300-degree-Fahrenheit) lithium fire inside your engine compartment within 5 seconds. Double-check the + ndi - post markings with a flashlight before ever touching the Override button.
3. Unclip the lithium jump pack within 30 seconds after the car starts: Once the vehicle's engine fires up, its alternator immediately begins outputting 14.2 ku 14.8 volts at up to 150 amps. Leaving a handheld lithium jump pack clamped onto a running engine for several minutes forces high-amperage alternator current backward into the lithium cells, causing the pack to overheat, puff up, and burst into flames. Remove the black negative clamp immediately after the engine starts, and never store a lithium jump pack in a 65-degree-Celsius (150-degree-Fahrenheit) summer glovebox where heat degrades cell separators.

Mafunso omwe amafunsidwa pafupipafupi¶

What should I do first if a car battery explodes and splashes battery acid into my eyes?¶

Immediately flush your eyes with a continuous stream of clean water for at least 15 to 30 minutes while holding your eyelids wide open with your fingers, and have someone call your local emergency number (911, 112, or 999). Car battery electrolyte is 35 to 38 percent sulfuric acid, which can permanently blind you within seconds if not diluted. Remove contact lenses while flushing, tilt your head so the wash water runs away from the uninjured eye, and NEVER put baking soda or any neutralizing chemical into your eyes, as the chemical reaction generates heat that causes severe secondary thermal burns on the cornea.

Why did my car lose all electrical power after I accidentally hooked up jumper cables backward?¶

When jumper cables are connected in reverse polarity (Red to Negative and Black to Positive), automotive manufacturers protect the vehicle's expensive engine computer (ECU) by placing a high-amperage sacrificial Main Battery Fusible Link (typically an 80-amp to 150-amp cartridge fuse located in the under-hood fuse box or bolted directly onto the positive battery clamp) at the very front of the electrical system. That main fuse blows open in milliseconds during a backward jump-start, cutting off 100 percent of power to the dashboard, starter, and lights. Replacing that blown main fusible link (by unbolting its side retaining screws) along with any blown 10A/15A EFI or ETCS mini-fuses usually restores the car to normal operation.

Why should the last black jumper cable clamp go on unpainted engine metal instead of the negative battery post?¶

Lead-acid car batteries naturally vent invisible, highly explosive hydrogen and oxygen gas through their top caps, especially when discharged or being charged. Because attaching the fourth and final jumper cable clamp completes the live electrical circuit, it almost always produces a small electric spark at the moment of contact. Clamping that fourth lead onto an unpainted metal bolt on the engine block or strut tower at least 30 to 45 centimeters (12 to 18 inches) away from the battery makes sure that the completion spark happens safely away from the battery's hydrogen gas cloud.

Why is it dangerous to jump-start a dead car battery in sub-zero winter temperatures?¶

Ngakhale batire yagalimoto yodzaza kwathunthu siundana mpaka kutentha kutsika pansi pa 60 digiri Seshasi (kuchepetsa madigiri 76 Fahrenheit), electrolyte ya batire yomwe yafa kotheratu imasandulika madzi osavuta ndipo imaundana kukhala ayezi pafupifupi madigiri 7 Celsius (20 degrees Fahrenheit). Kukula kwa ayezi mkati mwa batire yowundana kumaphwanya mbale zam'kati zokhala ndi kagawo kakang'ono ndikumangirira mpweya wotuluka pamwamba; ngati mulumikiza zingwe zodumphira ku batire yowundana, pompopompo imatchera gasi wa haidrojeni pansi pa kukanikiza kwakukulu ndipo imapangitsa kuti batire yodzaza ndi ayezi iphulike mwamphamvu. Nthawi zonse fufuzani mbali zophulika kapena ayezi musanadumphire m'nyengo yozizira.
