Title
(EN) Removable Real Time Clock Battery Assembly
Abstract
(EN)

A removable real time clock battery (“RRTCB”) assembly is disclosed herein. The RRTCB assembly has an outer housing removably mounted in a port of a downhole tool. The outer housing is adapted to receive at least a portion of an inner housing. The inner housing has a cavity therein and is mounted in the port of the downhole tool. The inner housing is removably disposed within the outer housing. A real time clock battery is removably disposed in the cavity of the inner housing. The real time clock battery electrically connects to a clock disposed within the downhole tool. The RRTCB assembly can be readily removed from the downhole tool or bottomhole assembly (while at the earth's surface) without otherwise disassembling the downhole tool. The real time clock battery can then be removed and replaced or installed if not present.
