Question

Which of the following should not be done for maximum life of battery?

  1. Slowly add acid to distilled water
  2. Vent holes should be clear and vent plugs should be properly secured.
  3. Both a and b
  4. None of them

hintHint:

Adding acid to distilled water, and venting holes clear will not increase the life span of the battery.

The correct answer is: None of them


    Both a and b can't be done to increase the life span of the battery.
    • The life span of the battery can be increased by storing them at or below room temperature and keeping them away from the metals.
    • Adding acid or venting the plug properly will not increase the life span of the battery.
