A continuous input of current to a storage battery is called what?

• A. Floating charge
• B. Trickle charge
• C. Maintenance charge
• D. Boost charge

Answer: (A)

Maintaining a storage battery at full charge with a small, continuous input is called a float charge. After the battery reaches full voltage, the charger supplies only a tiny, stable current to compensate for self-discharge and leakage. This keeps the battery ready for use without pushing more charge in, which would risk overcharging. Trickling is a low-rate charge used to top off or recover charge, not to continuously maintain a fully charged state. Boost charging is a rapid recharge from a discharged state, and a maintenance charge is a broader term that doesn’t specify the continuous, current-limiting method used in float charging.
