12V 85AH Multi-Purpose AGM Battery (ES12850)

🔋 PREDATOR ES12850 MULTI-PURPOSE AGM BATTERY – 12V 85AH

General-Purpose VRLA AGM Battery – 12V, Supplied 80Ah C20 Capacity, Maintenance-Free Construction & Standby / Light-Cycling Capability

⚡ The Predator ES12850 is a 12V multi-purpose Absorbent Glass Mat battery designed for everyday general-purpose, standby, float and light-cycling applications.

Part of the Predator ES range, the ES12850 uses VRLA AGM construction with compressible glass mat separators positioned between the battery plates. These separators retain the electrolyte required for the battery’s internal chemical reaction while helping reduce internal resistance and improve overall battery efficiency.

The supplied product title identifies the ES12850 as an 85Ah battery, while the detailed technical specification lists a 20-hour rated capacity of 80.0Ah. Both supplied figures are retained in this listing so the discrepancy is clear.

With maintenance-free construction, low self-discharge characteristics, a high-strength ABS casing and supplied internal resistance of no more than 6.0mΩ when fully charged, the ES12850 is suited to a broad range of compatible electronic, backup-power, automation, security, telecom and control applications.

The supplied product information also states that the Predator ES range is approved under the CSIRO ActivFire Scheme and listed in the Register of Fire Protection Equipment for fire panels and systems.
