Replacement Battery for 530le 730 740 745 Models

This lithium polymer battery operates at 3.7V with a 580mAh capacity. It replaces the MKD35UP and matches part numbers including 9442976-01 and D-80788. The unit suits owners of compatible 5310le 760li LCD Key Battery devices needing a direct swap.

Simple Drop-In Installation

The pack fits the original compartment without soldering or cable modification. Align the connector and press until it seats. A common issue is a loose fit if the retention clips on older 730 or 740 chassis have worn down over time.

Steady Output During Extended Use

The chemistry maintains a stable 3.7V through long typing sessions or standby periods. Voltage sag stays minimal compared with aged original cells. Runtime scales with the 580mAh rating rather than peaking early and fading fast.
