Query: Poor replacement battery

I purchased this replacement battery awhile back and it never was as good as the original one was at the time of original purchase. The charge only holds a short time. It also almost cost as much as the battery + the original tool would have cost new. If I had it to do over again, I would just go out and buy another drill and avoid the "Skil" brand.
