Yes, alkaline battery corrosion can move up wires or circuit boards. It usually starts at battery terminals. . Battery terminal corrosion is more than a nuisance—it increases resistance, causes intermittent no-starts, and can point to deeper problems like acid leakage, loose hold-downs, or an overcharging alternator. It can cause starting issues, reduce performance, and even damage electronics. In other words, the rechargeable battery may not be allowed to maintain a charge and if it does have a charge, the battery may not be. . Knowing how to clean corroded battery terminals properly is essential to restore good electrical contact, improve conductivity, and extend your battery's lifespan. Corrosion occurs when acidic battery fumes react with metal terminals, creating a crusty, conductive-resistant buildup.
