DC Charger for Generator black start
(OP)
I am purchasing a 2.5MW generator recently. Vendor indicates that they the Lead acid battery charger will come with their package. But the client insists on using Ni-Cad Battery since it is their standard. I wonder if there would be any issue if we use NiCad Battery in place of lead acid type. Any inputs would be highly appreciated.

I.e., they thrive on use and abuse, so be sure to be very rigorous about scheduling and conducting generator startups.
NiCd battery assemblies are usually sized so that a decent lead-acid charger of the same nominal voltage won't kill them. Some of the fancier industrial chargers will have a switch or other adjustment for battery chemistry. Check that the charger you are being offered is documented to work ok with NiCds.

Flooded cells will have a long life, and some of the newer designs use recombination to minimise gassing and electrolyte loss. Get a purpose-designed charger, a lead-acid charger will shorten the life of expensive cells.

Buying a 2.5MW set is not like buying a 2.5KW set, the buyer should be able to specify a ni-cad battery and charger if desired with no issue. I would be sorely tempted to explain to the (prospective) vendor that a suitable ni-cad charger will come with the set if they want the sale. Of course, I am not used to having all kinds of money to throw around.
