This battery does not properly fit the 7 1/4" circular saw, model #5850 because the mounting track flange is JUST A TAD wider than OEM battery packs, and the pack runs into the grip and won't go any further. This requires a bit of trimming of the grip on the saw to allow enough clearance. My other tools, the jig saw, the recip saw, and the drill, all work as normal, since any grip material does not butt up against the battery track.. Just be aware of this little oddity before buying, and keep a Dremel tool with a grinding wheel handy. This pack works on either the older Ni-Cad charger, or the newer lithium-ion charger. I just tested this before making this review. Overall, I'm sold. I spent good money on two OEM lithium-ion packs, which lasted maybe two days. The design on THOSE was poor - meaning that there should have been cell balancing employed to help boost weaker cells to full potential, when others had reached full charge. I did not open THIS PACK. Hopefully, someone thought ahead enough to set it up properly. Read full review

June 12, 2019 The picture is false and the description is deceptive. I wanted what was in the picture and described but that is not what I got. The picture shows 2 prongs but these batteries actually have 3. None of my 4 tools or 6 chargers accept 3 prongs. That means I can’t charge these batteries up to the Ah run time advertised and even if I could my tools could not utilize that power. If the picture had shown all 3 prongs I would not have bought them.

I just used the two batteries and was able to run my pole saw and trimmers up north for the entire time without a recharge where as my old 2 OEM batteries were requiring a charge to finish about the same amount of work. Bad news is I had to keep working with out a break????

Batteries are hard to find anywhere else, so I'm relieved to get them as I have three tools I use with them -- leaf blower, hedge trimmer, and grass trimmer. It would be a shame to have to buy a new set of tools because their battery is no longer available. Thank you!

This Battery was a great value and works like a charm. My old battery would not hold the charge. This worked for multiple times such as week wacker and blower. So very happy with this purchase!
