Prior to adjusting the electrolyte level, the battery must be charged and allowed to sit for how long?

• A. 30 minutes
• B. 2 hours
• C. 1 hour
• D. 4 hours

Answer: (B)

After charging, a flooded lead-acid battery needs time for the electrolyte to settle and for the cell temperatures to equalize before you measure the level. Waiting about two hours lets any gas produced during charging escape and lets the electrolyte distribute evenly across the plates, so the level reading is accurate. If you check too soon, readings can be off due to recent expansion from charging, which can lead to overfilling or incorrect water additions. The shorter times don’t give enough stabilization, while four hours isn’t required for this procedure.
