Replacement battery for Areca controllers

This 1800mAh 3.7V lithium cell replaces the original battery in Areca ARC-1884-(8/12) and ARC-8050T3-12R/24R/SAN controllers. It also fits ARC-8088, ARC-12xx(ML) and ARC-1882P models. The pack matches the factory specifications and includes overcharge, over-discharge, over-voltage and short-circuit protection. It is sold as a single unit.

Fits the controller cache module directly

The battery measures 52.0 x 36.8 x 10.6mm and weighs 64.0g, matching the original form factor so it slots into the existing holder without adapters. A 6.66Wh rating provides the energy needed to preserve cache data during power loss. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS for safety compliance.

Suits administrators maintaining listed Areca RAID

Buyers who need a different voltage, capacity or connector should look elsewhere. The cell is not compatible with controllers outside the ARC-1884, ARC-8050T3, ARC-8088, ARC-12xx(ML) and ARC-1882P families. Verify the part number against ARC-8008-FBN, 91-800602-0300 or the other listed codes before ordering.

Questions about this item

How long does the 1800mAh 3.7V lithium cell last under continuous RAID controller cache backup load?

The 1800mAh 3.7V lithium pack delivers 6.66Wh, so runtime depends on the controller's actual cache-backup current draw; the cell itself has no fixed hour rating.

Does the pack run hot or make noise during 24/7 operation inside an Areca enclosure?

The sealed lithium cell has no moving parts and generates negligible heat at typical cache-backup currents; it is silent in operation.

Which Areca RAID controller model must I already own for this ARC-1884- replacement to fit and connect?

It fits ARC-1884-(8/12), ARC-8050T3-12R/24R/SAN, ARC-8088, ARC-12xx(ML) and ARC-1882P controllers that use the original 52.0 x 36.8 x 10.6mm battery.
