Compatible Replacement Battery

The Estry lithium battery replaces the original power cell in Xplorer and Xplorer Plus devices using part numbers 4861 601.000 or H451987.

Measuring 74.5 x 21.5 x 5.5mm and weighing 44.0g, the pack fits the existing battery compartment without modification. The integrated safety circuit supports safe daily charging cycles and helps extend overall service life. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS for quality and transport compliance.

Single-Cell Lithium Constraints

The 1.67Wh energy rating limits runtime to the original device design envelope. Users needing longer operation between charges cannot exceed the fixed 500mAh maximum capacity of this form factor. The 3.7V output suits only equipment specified for this voltage; higher-voltage systems are not supported.
