Is it compatible with the 40 volt hartz battery

I'm not sure because I only have a Kobalt battery but this week I will be going to the battery store and see if they have a cheaper battery for this charger then I can let you know if it works with my charge if the battery is not a Kobalt.

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

I have the Kobalt quick charger, 6Ah also. It nicely charges my 4Ah batteries. I think it will charge anything less than its max of 6Ah.

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

Yes, the Jailapok 40v battery will indeed work with this charger. However, this is NOT an off-brand charger; it is a genuine Kobalt charger and it works great.

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

Yes; I bought a 2nd charger and battery to add to what was included with the original purchase package of blower, charger, battery. The identifying information is the same on the items. I have been using them successfully for about a year.
