sufeKobalt 40 Volt Power Equipment Battery, Gen3 Fast Charger

Is it compatible with the 40 volt hartz battery

Will this charge a Kobalt 40v max 2.5 Ah (this listing has 6.0 Ah) lithoum ion battery?

Does anyone know of the off brand jailipok 40v 6mah battery will work with this off brand charger?

Does it work for the 4-Amp 40v battery?
