heat effects on car battery
Extreme temperatures can have deteriorating effects on car batteries. Extreme Heat. Extreme under hood heat allows the battery to reach high internal temperatures (140Â°+ F/60Â°+ C). Extreme internal battery temperatures allow the lead plates to corrode and deteriorate.
The intense heat can speed up the chemical reaction inside the battery, causing an increase in self-discharge and plate corrosion, which eventually leads to sulfation (crystals forming on the battery plates) and then the battery will become unrecoverable even with normal charging.â.
Depending on where you live, or what time of the year it is, the performance or life of a flooded car battery can be drastically compromised. For example, in many southern states, where extremely high temperatures during the summer are normal, heat can wreak havoc on car batteries.
