SEALED LEAD-ACID REPLACEMENT RECORD
Yenra | Updated September 7, 2026
Article: https://yenra.com/batteries/sealed-lead-acid-battery.html

Purpose: prepare an approved battery replacement inquiry for ordinary supported backup/low-voltage equipment. Fill in from the exact equipment manual, accessible labels and manufacturer documents. This record is not a wiring or charging procedure. Critical, medical, mobility, traction and large-string applications require their own approved service arrangements.

Equipment make/model/revision:
Equipment manual URL and revision:
Existing battery or cartridge part number:
Supported replacement part number and approval evidence:
Battery manufacturer and exact model:
Construction (AGM/gel/other as specified):
Nominal voltage (V):
Rated capacity (Ah):
Capacity test period (hours), temperature and endpoint voltage:
Length x width x total height (mm):
Terminal type/size (mm), polarity layout and case specification:
Intended duty (standby/cyclic) and operating temperature:
Supported charger/model/profile and documentation:
Required enclosure/ventilation and installation orientation:
Qualified provider resolving any specification conflict:

RUNTIME EVIDENCE
Load and units (W or A), representative and peak:
Current exact-model discharge curve or complete-device runtime curve:
Cutoff voltage, temperature, age and losses used in estimate:
Required runtime and supported estimate:
Fictional label exercise: 7 Ah / 20 hours = 0.35 A average test current. Nominal 12 V x 7 Ah = 84 Wh as a comparison, not guaranteed delivered energy or one-hour runtime.

SERVICE RECORD
Approved replacement procedure reference:
Replacement date and provider:
Prescribed device self-test/status result:
Next inspection or test required by equipment maker:
Retailer or hazardous-waste program receiving old battery:
Receiving program packaging instructions:
Do not open a sealed battery or add water. Use the maker's fault procedure for swelling, leakage or unusual heat. Do not discard lead-acid batteries in household trash or municipal recycling.
Unresolved item and decision:
