That's exactly what it is. They are protected from getting too hot, since charging puts heat into them as well. I've used my Milwaukee stuff hard enough the batteries shut down, because they get too hot, even if there's still a charge on them. Once they cool down, they can be used, or charged.
I would think the battery is too hot and its light flashes red not green when trying to charge. This light has never flashed red with any of the other tools.
The MSA 300 with 20" bar, chain, and battery weighs 17.5 lbs, and the AP 500 s battery weighs 4.3 lbs.
If you're happy that's all that matters! Edit: For clarification......I was asking because my cousin and I started a business together and he got out after 6 months. We both bought cordless tools and batteries. Just after 3 years, my batteries were so shot, the run times were short and they didn't have the power they used to. My cousins batteries were still more than useable and in operation 8 years later, because he didn't use his as much as mine. So, context in these situations do matter. Hence my curiosity.
Our first battery saw was a Yardworks bought from a big box store. It didn't last one chain! Next was a Stihl MSA 160 with a 12 " bar and an AP 160 battery. It's eleven years old and still going strong. Stihl was chosen for its good reputation and has not disappointed.
We are straight north of them...so the wind didn't often bring that stench directly to us (1000' away) but we'd catch a wiff once in a while...we'd have had issues if it was more then that. I heard that when the railroad corporate office got wind that the local office was letting people take old ties, and what they were being used for, they shut it right down.
I've smelled ties burning before. Almost repulsive. Neighbor burned some of his old lanscape ties a couple years ago. Lucky me, wind blowing my direction that day. I'm pretty sure Makita is about to release a full sized battery saw that will use their backpack which accepts and ties together multiple batteries. I'm still investing in ICE power saws as they are just a much better option for what I need from a saw. I know advancements have been made, but they still have much work to do if they wish for me to replace what I have with electric stuff. They will have to invent a new power storage device to ever fully replace a 60cc+ gas powered chain saw. That is of course, my opinion.
Glad they are meeting your expectations campinspecter batteries have gotten a lot better in the past 20 years! My reasoning 20 years ago every house builder had a backup corded drill for when batteries where dead or charging.. almost no one still has them in the truck
I still carry one around. I went through my batteries for all my tools this spring and ended up replacing 10 five amp hour batteries. Suckers are getting expensive!
