Battery capacity is commonly stated as a value of current delivered over a specified period of time. What is the effect of exceeding that specified current?
- AOne or more cells may become short-circuited
- BThe battery will accept the subsequent charge in a shorter time
- CThe voltage delivered will be higher
- DThe battery will discharge more rapidly than specified
Correct answer: D — The battery will discharge more rapidly than specified. From the official ISED question bank, verified word for word.
Why
When you draw more current from a battery than its rating allows, the chemical reaction inside speeds up, causing the stored energy to run out much faster than the manufacturer's specified time. The full explanation — and one for every question — is in Pro.
