Replacement Battery for AS/400 57B7 5679

This 3500mAh lithium polymer pack replaces the original power source in compatible AS/400 systems. It matches part numbers 74Y5667 and 44V4145 and delivers 12.95Wh at 3.7V. Buyers who need a different voltage or a higher capacity will not be served by this unit.

Upgrade from Depleted Original Cells

The battery restores runtime lost to ageing cells without changing the form factor or connector layout. The jump is worth it when the original pack no longer holds a charge through a typical work session. Systems that require a different part number or a non-standard connector cannot use this replacement.

Steady Output Under Continuous Load

Lithium polymer chemistry maintains a stable 3.7V through the discharge cycle rather than sagging early. The pack is certified to UN38.3, MSDS, ISO9001, RoHS and CE standards for safe sustained operation. It is not designed for hot-swap bays or parallel multi-battery configurations.

Questions about this item

What form factor does the 3500mAh lithium polymer cell use to fit the AS/400 57B7 5679 bay?

The battery is built to the original dimensions for the AS/400 57B7 5679 compartment and uses the same 3.7V 12.95Wh lithium polymer pack, so it seats directly without adapters.

Which step do installers most often miss when replacing the 74Y5667 44V4145 pack in an AS/400 system?

After inserting the cell, the connector must be fully seated and the latch engaged; a loose plug is the most common reason the unit will not power on.

When will the 3500mAh Li-ion cell typically need replacement under normal AS/400 57B7 5679 use?

Expect two to three years of daily charge cycles before capacity drops below useful levels; the UN38.3 and ISO9001 certified pack is rated for hundreds of full cycles.
