Battery Technology CP-BATT-8821-BTI 3.8 V 7.6 Wh Replacement Battery

Restore portable-device runtime with a replacement battery carrying a 3.8 V electrical rating and 7.6 Wh energy capacity. These values are the primary electrical identifiers to compare against the battery being removed. The 7.6 Wh rating states the battery’s stored-energy capacity, while the 3.8 V rating must match the equipment’s battery requirement. Battery Technology CP-BATT-8821-BTI is cross-referenced to GP-S10-374192-010H and 35-100138-03. Those references provide additional label numbers for technicians replacing an installed battery where the original label may use a different ordering convention. Match all available identifiers on the existing battery before fitting a replacement. For field maintenance, inspect the removed battery label, terminal arrangement, physical fit, and required electrical rating before installation. A battery with the same voltage and energy rating can still differ in contacts, dimensions, controller interface, or retention method, so physical and equipment-specific matching remains necessary. After fitting the battery, verify that it seats fully in the device and that the equipment recognizes and charges it normally.
