Replacement battery for HP iPAQ h4100 series

The Cameron & Co DS-CS-IP4100SL is a 3.7 V 1200 mAh lithium-ion cell built to replace the original 343110-001 pack in HP iPAQ h4100, h4135, h4150 and h4155 Pocket PCs. It restores mobile power for professionals who still rely on these legacy handhelds for data collection or field notes.

Capacity and voltage limits of a single-cell

At 4.44 Wh the cell delivers only the energy the original design allowed, so runtime matches the factory specification rather than extending it. The fixed 3.7 V output and 1.2 Ah rating mean the device’s power-management firmware sees no change, avoiding calibration issues.

Upgrading from a depleted or swollen original pack

Owners whose iPAQ no longer holds a charge through a work shift gain a direct, 100 % OEM-compatible swap without modifying the handheld. The jump is worth it when the old battery shows reduced capacity, physical swelling or sudden shutdowns under load.
