I have bought batteries from Pro Match since the black 1700 days,I have also owned a turbo matcher of some version or another since then.
That being said you WILL NOT find batteries with any more repeatable numbers.
I recently ordered a couple packs from Fukuama simply because Jeff is so busy that its hard to get specific numbers from him,and since I am currently running mod oval a few seconds of runtime is important .
These are the first packs I have bought from anyone other than Pro Match for almost five years,I only hope they will be as good as The PM batteries that have put me in several A mains and a 2003 region 8 paved oval win.My off the shelf PM packs are as good or better than several of my friends batteries that are on the so called deal. I wont stoop to your level by mentioning names but there are several matchers I wont buy from.
And best part is if your not happy.............
