battery maintenance

Battery charging equipment is generally installed

• In a well ventilated place

• In clean and dry place

• As near as practical to the battery being charged

• In location having all above features

Battery container should be acid resistance therefore it is made up of

• Glass

• Plastic

• Wood

• All of the above

Following will happen if battery charging rate is too high

• Excessive gassing will occur

• Temperature rise will occur

• Bulging and buckling of plates we occur

• All of the above

The following indicate that battery on charge has attained full charge

• Colour of electrode

• Gassing

• Specific gravity

• All of the above

To prevent local action in battery, only ............is used in electrolytes

• Pump water

• Distilled water

• Tap water

• Both A and C

When two batteries are connected in parallel, it should be ensured that

• They have same emf

• They have same make

• They have same ampere hour capacity

• They have identical internal resistance

If a battery is to be charged at a much higher rate as compared to normal charging rate, the charging should be restricted to

• 95% of the capacity of battery

• 80% of the capacity of battery

• 55% of the capacity of battery

• 35% of the capacity of battery

A dead storage battery can be revived by

• Adding distilled water

• Adding so-called battery restorer

• A dose of H₂SO₄

• None of the above

Cell short circuit results in

• Low specific gravity electrolyte

• Abnormal high-temperature

• Reduced gassing on charge

• All of the above

If the battery is wrongly connected on charge following will happen

• Current delivered by the battery will be high

• Current drawing will be Nil

• Currently drawing will be very small

• Currently drawing will be very high
