Replacement Battery for Surftest SJ-201

This 6.0V nickel-metal hydride pack replaces part numbers 12BAA240, 5HR-AAAU and 2261584 in the Surftest SJ-201 surface roughness tester. It supplies 700mAh capacity and 4.2Wh energy for portable measurement work. The pack measures 132.8 x 51.5 x 11.0mm and weighs 112.0g.

Ni-MH Chemistry Limits

Nickel-metal hydride cells self-discharge faster than lithium types and lose capacity if stored fully charged for long periods. They require a charger matched to 6.0V Ni-MH chemistry; using an incompatible charger can trigger the built-in over-voltage or short-circuit protection. The pack operates safely within the temperature range certified by UN38.3 testing.

700mAh Capacity Decides Fit

The 700mAh rating determines how long the Surftest SJ-201 runs between charges. If the original battery was rated higher, this pack will give shorter field time; if it was lower, runtime increases. Verify the part numbers above match the label on your existing pack before ordering.

Questions about this item

Which Surftest SJ-201 part numbers does this 6.0V 700mAh pack replace?

The 4.2Wh capacity delivers the same energy as the factory pack, giving identical operating time between charges for the SJ-201 profilometer.

Does the 6.0V Ni-MH chemistry limit charging current or require a special charger?

The pack uses standard Ni-MH chemistry at 6.0V and fits the SJ-201's built-in charging circuit; no external charger or current limit change is needed.
