stihl battery tools

I used the 220 top handle and rear handle today, and the 86 blower. Both of the saws were really impressive, I'm pretty stoked to have those at 80% off from a state funded voucher. The blower was a little weak but that's okay, saws were great!
How did you get an 80% off state funded voucher? What state? I want more battery tools at 80% off :-)
 
I can tell you that heat kills, even lithium. Fully charged cells left in a hot metal box in the sun wear out faster than if they are stored cool. Leaving batteries fully discharged for any length of time wears them out faster.
Also last summer (day was +30 degC in the PM/ sorta partly cloudy) had Husky BLi300 battery on charge in the sun on a walkway where we were working, came back after a bit and it didn't charge - presumably some sort of thermal protection? Went to gas. Later, moved the charge gizmo to the shade on the other side of the building and it did charge after a time. So charge outside where it isn't in the sun? But didn't seem that hot.

The sun makes it get a lot hotter. 30⁰c isn't too far from their operational limits.
 
It's sorta the way I feel about the whole battery thing right now - you have to watch rain (at least in the early days they didn't really say the battery stuff was OK with real wet), they get hot if you push the saw, the charging has to be in the shade, and where'd I put all those extra batteries anyway, etc. Don't get me wrong, they have their place. The longevity thing is still an open question, at least with me too. I do wonder what a future archeologist would think if they were diggin thru the ruins of our collapsed house one day and came across the many and varied collection of batteries and chargers we seem to be accumulating at a great rate lately. I can hear Spock say, "Curious".

Agree, battery saws have their place but they are no way a replacement for displacement. I been cutting up 3 casaurinas in the water. They fell in the sea after Beryl passed. Iron wood is no place for a battery saw. Not even brush. Just too fucking hard. That being said I hit metal twice..with a 42" bar on a 3120xp and a 36" bar on a 395xp. I packed up and went home. It was my third time. Only 3 cuts were made. I love gas saws.

At my elevation the uv is so intense, I never leave anything in the direct sun. It's a bit of a mania but damn things degrade quickly here.

What about cold weather/winter?
 
What about cold weather/winter?
I can talk to that a bit - was trying to recharge DeWalt batteries for a blower outdoors at the church last week - it was like they didn't want the electrons anymore - at only 5 deg C or so a normal < one hour recharge took two hours or more, even on the sunny side of the building. I found later that cold (or cool) affects recharging electric cars as well - their batteries recharge at much slower rates in the cold than at 20 or 25 deg C. New one on me.
Battery stuff generally doesn't last as long on the discharge/ use side either in the cold - I keep my spares indoors or in the truck until I use them if it's cold. But still in the cold gas is king in my book.

The problem in the cold is that the energy moves like molasses. It flows slower in either direction, and it will register at a lower voltage, so most things will act like the battery is dead when technically, there is a useful amount of energy in the cells. It's kinda like it's trapped in there.

So fundamentally, batteries like the cold, and last longer when kept cold, partly because they can't be discharged as deeply, and depth of cycling affects cycles to failure. In stationary systems, the solution is to oversize your battery bank enough that it provides the required amp hours. For portable power, this is seldom practical since most electronics get upset when they don't get their specified voltage range, and more amp hours weighs more, thus making such a system less portable.

I concur with ghostice. In the cold, gas wins every time.
 
Not Stihl related, but....

I just want to say yesterday, out of the FIVE Husky QC500 fast chargers I have had, I just had the THRID die on me. Husky knows about this problem, even on their own websites reviews! They are around $150 each.

I choose 40 c80 charger for 200x husкys battery.I suppose/thinк what longer charging means longer battery life.Am I right or not?What model of that blacк charger on table?

The black one is the cheapie model that came with the battery blower. WAY slower than the orange rapid chargers.
 
I have two of the cheap black chargers as I've bought two blower/battery/charger packages. Neither gets much use (because I always opt for the faster chargers unless I need to charge 4 batteries at a time, which happens) but both still work fine.
