I have the same drill and purchased a 2 pack of Munikind 3.6 Ah batteries #DC9096 on Amazon 6 months ago.. Haven't used them on the ice yet but they are holding a charge and seem to power my 18V Dewalts fine. Price point is $34.99 for two. I'm sure there are after markets that are junk but these have a good 1 year, 30 day money back warranty. Good Fishin !
