A waste of time and money
Like many others, l thought l was purchasing these batteries from a UK based supplier only to find it came from China. They are not worth buying. I bought 2 Hilti replacement batteries a couple of years ago and whilst they fit the drills. they don't last for long. I have used them and charged them and now they are defunked. A complete waste of money. The original Hilti batteries are the best value for money even if they cost more.
