Verified 2026-10-29 Confidence: High

Battery Cell Voltage and Specific Gravity is specified for valve-regulated lead-acid batteries in maintenance testing at clause 7.18.1.3.B.3 of ANSI/NETA MTS-2023. The clause calls for each monoblock or cell voltage and the total battery voltage to be measured with the charger energized in float; the clause names no specific gravity reading for a valve-regulated cell.

Value: valve-regulated lead-acid batteries
