Questions about this item

How long will the 2300 mAh rating actually run a Fieldpiece SRL2 leak detector?

The 3.7 V, 2300 mAh cells store 8.51 Wh each; run-time depends on the detector's current draw, so divide 8.51 Wh by the device's wattage to estimate hours per battery.

What charging standard does the built-in protection circuit follow for these 3.7 V lithium-ion cells?

The pack meets UL 1642 and CE safety standards and includes over-charge, over-discharge, over-voltage, over-current and over-heating protection; use a charger designed for single-cell 3.7 V Li-ion.

Will the 3-by-2-by-3 inch dimensions fit the battery compartment of a Fieldpiece SCL2?

Each cell measures 3 x 2 x 3 inches; verify that the SCL2 compartment matches those external dimensions before purchase.
