Direct Replacement for Surftest SJ-201

This Estry Ni-MH battery pack is built to match the original specifications for the Surftest SJ-201 surface roughness tester. It replaces part numbers 5HR-AAAU, 12BAA240 and 2261584. Technicians maintaining this specific metrology instrument can install it without modification.

Nickel-Metal Hydride Chemistry Limits

The 6.0 V pack delivers 700 mAh capacity and 4.2 Wh energy. Ni-MH chemistry exhibits self-discharge over long storage periods and performs best within moderate temperature ranges. It lacks the high energy density of lithium alternatives and requires proper cycling to maintain full capacity.

Capacity Suited for Portable Metrology

The 4.2 Wh rating supports typical field measurement sessions on the SJ-201 unit. Extended continuous logging or frequent backlight use will deplete the pack more quickly. Users planning all-day unattended operation should keep a spare charged pack available.
