Chainsawrepair = cut4fun ( my old username everyone knew me by )

What is the difference in the 2 battery's offered and how are they about holding a charge after long periods of no use? I just hate when I go to grab my cordless drill and the battery is flat.

How will weather temps effect the holding of the charge?

Also, how many times can you charge the battery before it goes bad?

Lithium batteries do not loose their charge setting on the shelf like the old NiCds do.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".

I'm going to post a link to our FAQs online.  It has the information you are looking for.

http://www.oregonpowernow...s.com/docs/Blount_FAQ.pdf

Cut4fun:  Items number 1, 2, 5, 14 and 19 will address your questions about the battery packs.  The saw does fine in cold weather. If it sits overnight at below 32˚F it may not run until the battery is warmed. When using the CS250 in cold weather, simply keep the battery pack above freezing until ready to cut. As you start your job, the battery will most likely stay warm enough to continue running.

man of stihl:  Item number 3 answers your question.

660magnum: Li-Ion batteries do lose some charge while sitting, but not nearly as drastic as Ni-Cad do.  Item number 19 addresses the amount.

Good questions all.  I hope I provided the information you were looking for.

As some of you are aware, in 1965 Oregon released a chain called Topsharp that ultimately failed. (a.k.a. Barracuda) This was mainly due the stone being shaped by the cutters and OEMS doing a poor job of implementing the sharpening system into their saws.  The new PowerSharp on the market today has been re-engineered to correct the mistakes made in the older version.

We currently have two applications for PowerSharp on the market.  One is the system built into the PowerNow CS250 Chainsaw and the other is an aftermarket setup for gas saws.  The aftermarket kit includes a bar, sharpener, stone, and a chain.  The 2 systems are the same except the way it is applied to the saw.  PowerSharp on the CS250 is applied with a lever built into the saw and the gas version has a spring loaded sharpener that is attached to the bar and depressed against a solid object.  PowerSharp sharpens from the top down just like the old Topsharp.  As the chain is passing through the stone it is performing 3 functions.  It is sharpening the cutters, setting the depth gauges, and dressing the stone.  The cutters and depth gauges are able to be ground at different lengths because we are sharpening on a radius.  The stone is being dressed by a diamond coated link (the only gold colored link) that makes sure the stone is always the correct shape to properly grind the cutters throughout the life of the chain.  If performed at the proper intervals (3-5 seconds), there is no danger of overheating and annealing the cutters. The system on the CS250 averages 10-20 and the gas saw averages 5-15 sharpenings per chain/stone (Difference due to chain RPM).  The chain and stone are designed to wear out at the same time and come together as a replacement kit.  As a design benefit, PowerSharp maintains it's edge 2-3 times longer than traditional chain because the chrome is laid on the underside of the cutter.  This was needed because the cutter is being ground on the top.  When traditional cutters force themselves through wood the chrome is constantly under pressure to peel back and off due to friction.  With PowerSharp the chrome wraps around the nose of the cutting edge and "holds on" to the cutter longer resulting in a harder edge which leads to better performance.

I perform demo's all the time by dulling the chain on concrete then re-sharpening to cut wood again.  I've even done side by side tests with used railroad ties.  The PowerSharp maintained it's edge on average twice as long as traditional chain in the gravel infused wood (lots of sparks while cutting).  I was able to perform a 3-5 second sharpening and I was on my way again.  With the traditional chain I had to stop and change out the loop.  It really does work.  I encourage you to visit the PowerSharp website to view the components I mentioned.  It may help you visualize the process. www.powersharp.com

I hope I actually provided some insight rather than just confusing folks...

Luke

How does the chain cut, speed wise, compared to hand round filed?

In smaller diameter wood you will most likely not notice a speed difference.  The larger you go, the more you will notice PowerSharp cutting faster.  Currently we only have PowerSharp in a low-profile 3/8" chain.  A .325" chain is in development, but I have no idea on timing.

MOS if I get a chance to try it I will try it fresh out of box against the new PS3 and another new semi chisel chain. That should tell me how the new stuff cuts.
