For use with all Mark-10 force gauges and torque gauges powered by rechargeable batteries. Note: The 08-1006 battery, which was used with legacy Mark-10 gauges (Series BG, BGI, EG, and CG), is no longer available. The AC1118 battery may be used instead, however, some gauge modifications are required to ensure proper charging characteristics. The gauge may be sent back to Mark-10 for modification, or the modification may be performed in the field.
