geruipu Posted June 14, 2019 Report Share Posted June 14, 2019 I want to find a power tool battery? I hope It can work for a long time. Where is such a supplier? Quote Link to comment Share on other sites More sharing options...
paulengr Posted June 14, 2019 Report Share Posted June 14, 2019 Panasonic! That's why when you open up the batteries on almost every tool battery you will find Panasonic lithium ion batteries. Dewalt, Milwaukee, Makita, doesn't matter. They all use the same manufacturer. They can very the model number and thus the size and society of the batteries and there are tons of arguments about various series-parallel arrangements but the actual cells are the same.However there is a temperature sensor and usually some kind of "size" feedback to the controller in the tool battery pack at a bare minimum, plus different contacts and some battery management stuff. This makes it hard to make a knockoff battery. Most knockoffs salvage old used battery packs at least for the electronics. But most also harvest old, used, but not yet failed batteries too and then add more salvaged batteries or out of spec grey market batteries (rejects) or even old lower capacity cells to it. So what you get is a Frankenstein battery. It might work for a while or it might not.Sent from my SM-T350 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

Jronman Posted January 18, 2021 Report Share Posted January 18, 2021 Any professional grade brand will used a cell of good enough quality to last years. Most brands are not compatible with the next you will need that brands tools to go with their batteries. Quote Link to comment Share on other sites More sharing options...

Modern batteries used by today's major brands are the result of years--if not decades--of research and experience as exactly what components/design factors make the best power source for a given tool. We have really seen this over the past five or so years, with each manufacturer releasing their version of high performance batteries for "smart" or high draw tools. FlexVolt, Milwaukee HO, Ryobi HP, etc. are all examples of batteries designed to complement smaller (2ah, etc.) batteries. To put this in perspective, ten years ago cordless circular saws generally used smaller blades (6-1/2", 5-3/8") and made due with the same batteries used in drills and the like (back then 3ah was standard for a "large" pack). Now you can get brushless 7-1/4" saws and have a choice of using a small battery--perhaps losing a little performance and lacking longevity--or using a 9ah or even 12ah battery that will run the saw for much longer. 1 Quote Link to comment Share on other sites More sharing options...
stream26 Posted February 13, 2021 Report Share Posted February 13, 2021 Dewalt, Makita, Bosch, take your pick. They're all making great, durable cordless tools. My Makita tools have become like plugins for my hands. They are effortless, intuitive and indestructible. https://onplanners.com/notebooks/best-notebooks-for-designers Quote Link to comment Share on other sites More sharing options...
