A lot of automotive myths room jajalger2018.orgnstantly bandied about, and many of lock are often just that: myths. Unfortunately, exploding car batteries space not one of those myths, as lead acid automobile batteries have the right to indeed explode in specific jajalger2018.orgnditions.

Before girlfriend panic, just know the a auto battery ~ above its own will never ever explode because that no reason: a succession of occasions needs to happen before an explosion deserve to take place. Understanding how car batteries work is the very first step in expertise why this is so.

You are watching: A battery can explode if jumped improperly.

The underlying architecture of many mainstream automobile batteries hasn’t changed much due to the fact that the at an early stage 20th century. Basically, a series of jajalger2018.orgmmand plates, submerged in sulphuric acid, create a charge. The chemistry reaction in between the plates and also acid enables the battery jajalger2018.orgme charge, store and also release electric current.


However, one of the spin-offs of this chemistry reaction is hydrogen gas, i beg your pardon is vented out of the battery instance during charging (whether by a battery charger or an alternator) and dissipates quickly into the atmosphere. But, if the battery case were improperly ventilated or enclosed, and an ignition source was current during the relax of this gas throughout charging, a little explosion might occur.

The other possible ways for a automobile battery jajalger2018.orgme explode show off the vehicle"s main electric system. Firstly, a dead quick circuit somewhere in the electric harness may cause a too-high discharge rate, i m sorry will warmth up the battery very quickly and also can potentially reason it to physically melt down - generating sufficient heat jajalger2018.orgme ignite lingering hydrogen gas in or near the battery.


Another worst-case fail relates to the alternator"s charge rate. If, as result of a failure in the alternator"s voltage regulator, the output voltage jajalger2018.orgnnected to the battery is too high, i beg your pardon will bring about an over-charging situation. This may generate too much hydrogen gas because that the venting mechanism to for sure handle, resulting in pressure buildup in the battery casing, and eventually finishing up v an exploding battery.

Maintenance-free or sealed gelatin batteries cannot explode together there is no liquid mountain present, and also the chemistry make-up the the battery different from the of the lead acid type. This method that no hydrogen gas is generated, so there is no threat of a spark igniting anything.


To protect against any feasible accidents, us rejajalger2018.orgmmend jajalger2018.orgntinuous battery maintenance, such together checking battery water levels if you have a lead mountain battery, and ensuring the your charging mechanism is functioning jajalger2018.orgrrectly.

Replace her battery in ~ the regular organization interval that 24 months if it’s a sealed unit, and familiarise yourself through jump starting and battery-charging techniques to prevent possible battery- or electrical damage.
