Final answer:
Technician B is correct. Overcharging can result in battery overheating.
Step-by-step explanation:
Technician B is correct. Overcharging can result in battery overheating.
When a battery is overcharged, excess electrical energy is converted into heat. This can cause the temperature of the battery to rise, potentially leading to overheating. Heat is generated due to the resistance within the battery and the internal chemical reactions.
For example, if a battery is shorted out by placing a wire directly across its terminals, the battery will begin to get hot. This is because the short circuit allows a large current to flow through the battery, generating heat from the resistance within the battery.
