Are you sure it charges at 14.4, or perhaps it is set for 4S lithium of the 3.6V nominal type, in which case it would charge to about 17ish volts.
Usually your biggest issue using a lipo charger for lead acid, is that the consumer type for electric tools and the such, will hopefully have safety mechanisms that can make it problematic to use for your application.
Also, you are unlikely to get a perfect match for battery pack voltage, so you need to do some modifications. Don't make the mistake of confusing the nominal voltage of any battery technology for the charge voltage.
Yeah, it will be unlikely to work. There are insufficient details to really answer your question, though.
