FAQ

Why use an external charger instead of the host device?

A dedicated CH4000 base lets you swap and charge spare packs without taking medical or industrial equipment offline, protecting uptime for critical diagnostic tasks.

Does it protect battery health?

Yes. Through the SBS / SMBus interface the CH4000 reads the battery BMS to deliver a precise charge cycle, with overcharge and thermal cut-off and LED status feedback.

Which part numbers does this charger support?

It charges NI2020HD24, NI2020IK24, NI2020ED, NI2020OL24, NI2020TS24, NI2020A24, NL2020ED, NL2024HD, NI2040, ND2054, DR202, DR202S, ME202C, ME202A and BP3S3P3450P-01.
