Two Li-Ion batteries and dual USB charger

This pack includes two Kastar NP-120 lithium-ion batteries and an LTD2 charger that powers both at once. Each cell delivers 3.7 V and 2300 mAh for 8.51 Wh of capacity. The charger accepts Micro-USB or Type-C input at 5 V and up to 15 W. It is designed for technicians who rely on Fieldpiece leak detectors daily.

Replaces single OEM cells and slow chargers

The bundle swaps out individual Fieldpiece RLB2 packs and basic single-bay chargers. Dual-bay charging cuts downtime when both detectors need power before a job. The jump is worth it when you run SCL2, SRL2 or SRL8 units back-to-back and cannot wait for sequential charging cycles.

Runs SCL2 SRL2 SRL8 leak detectors through typical

Two 2300 mAh packs give enough headroom for extended refrigerant detection work. Each bay outputs 4.2 V at 800 mA so both batteries reach full charge together. Heavy continuous use with maximum sensor sensitivity will drain cells faster and demand a mid-day swap.

Questions about this item

What physical space does the charger need for the dual-battery setup?

The charger measures 5 by 3 by 2 inches, so allow at least that footprint plus room for cables on a bench or in a tool bag.

How do I start charging two NP-120 packs with the LTD2 unit?

Plug the charger into a 5 V 2–3 A USB source via Micro-USB or Type-C, insert both batteries, and the LCD shows each cell’s status at 800 mA per slot.

When should I replace the 3.7 V 2300 mAh lithium-ion packs?

Replace them when run-time on your Fieldpiece SCL2, SRL2 or SRL8 leak detector drops noticeably or the charger’s LCD no longer shows a full 8.51 Wh capacity.
