Castles Technology S1F4 Spare Payment Terminal Battery

Keep a compatible replacement power component available for Castles Technology S1F4 payment devices when the installed battery needs replacement. This spare battery is assigned to the S1F4 platform, making compatibility the central selection criterion rather than battery chemistry, capacity, or connector assumptions. It supports maintenance work where the terminal must return to its normal portable operating role after a battery exchange. Use it for service inventories supporting mobile payment terminals deployed at counters, tableside positions, delivery handoff points, or other locations where an S1F4 is moved during operation. Match the device designation before installation; batteries that share a general payment-device category are not necessarily mechanically or electrically interchangeable. The product is a replacement battery, not a terminal, charging dock, power adapter, or communications accessory. Order 40100055-FP when the required item is the FDP S1F4 spare battery. The part serves a narrow replacement role for that device designation, rather than providing a general-purpose power option across payment hardware. Recording the S1F4 association alongside the ordering code helps service staff select the battery intended for the installed device. Its role is to replace the battery component without changing the terminal configuration or operating workflow.
