Actually, I'm not using patona-batteries. I prefer original battery-packs (in my DSLR, Notebook and as well Power-Tools)!
But I also now, that patona is well known for their battery-clones and should produce good quality!
Nevertheless, such battery-packs would work in your Power-Tool. But be aware, if such battery damages your tool, your warranty is gone!
If you want to buy such battery-packs, Amazon and Ebay offer patona.
