Which batteries do I need for TSC55?

Somebody please correct me if I'm wrong, but the TSC 55 will run on any one or two non-Ergo batteries and the Ah rating only affects the amount of energy stored in the battery which translates to the runtime. I believe that you will be fine using your two 3.1Ah 18V batteries, but will be charging them more often than with batteries with higher Ah ratings.pgrbff said:

I've operated my TSC with a single 15V 3.0A battery. However the blade speed is slower and obviously the battery doesn't last very long.
If you want the saw to work as designed, you need 4Ah and up.
I don't see any point in trying to run a relatively expensive power tool in a configuration that's not only sub-optimal, but specifically stated to be unsuitable by the manufacturer of the tool and the batteries.
Will it cut? Yeah, sure it will. But I wouldn't mess about when Festool say the 3.1's aren't compatible/suitable.

[member=60291]pgrbff[/member] there is an often overlooked aspect of batteries, that also matters here and that is how much current they can deliver instantly (know as discharge rate). This is going to be very different between the 3.1, 4.0 and 5.2 Ah batteries.
If the 3.1 Ah batteries aren’t able to deliver enough instantaneous current as the saw is cutting, the blade will bind and stop.
So as others have mentioned, if you want the tool to perform as it was designed to perform, stick with the 5.2 or 4.0 batteries at a minimum. Down the road this recommendation could change as new cells and batteries are developed, but for what’s available today, this is the recommended way to power the tool.

I have always told people that the TSC55 won't run (at all) on the 18v 3.1 batteries. Because when I put them on my saw it won't run at all.
Are those here who are saying that it will run, but slower, just assuming that is the case? Or have you actually tried it and had it run?
The reason I wish it would work is so that I could have only the one size 3.1 18v battery in my site work set up.

Well the old 15V batteries do work, I was forced into this scenario when i was mobile without any 18V batteries. I only had the C15 and the TSC with a couple of 15V, 3.0 batteries. I only needed to cut some short 3/4" ply pieces and it worked...it got me out of a jamb. [smile]
Would I recommend this as a normal work-around, probably not, just a data point as to what your options are. Would I go with the new 18V 4.0 batteries...probably not...better to have the 5.2's or 6.2's instead. Then again I'm a throwback to the 396...427...454 days...a 396 is close to being a mouse motor. [smile]
The 15V batteries also work in the new TSC-K version.

That’s exactly what I was thinking Richard…
Thank you all. I have only recently moved to Festool cordless. Having ordered the 18V impact drill, which came with 3.1Ah packs I was hoping I wouldn’t need bigger packs for the saw. If I’d known I would have asked the question before buying the drill, but it’s always easy with hindsight. Have bought two 5.2 packs for the saw.

Back when the Makita 18v LXT stuff first hit the market, they had far fewer tools. The first ones were all 3ah battery. After a few months, they released a more "home owner" oriented drill and driver with 1.5ah batteries, at a reduced price. They were white/black instead of the usual Makita blue, but otherwise very similar. I decided that I liked the smaller/lighter batteries better, so I used them with the blue impact too.
What I found out over time was that there was a difference in the batteries themselves. There was a little tab inside the sliding grooves of the tools that was different on the tools that needed the higher amperage. The smaller batteries would not fit in them. The big 1/2" hammer drill, 6 1/2" circular saw, and a few years later the jigsaw would not take them, yet because of the way this groove works, the bigger batteries would fit anything.
This was all more than 15 years ago, now battery amperage has gone crazy and they are stacking batteries to get 36v too.
