C15 and T12 Battery Questions
« on: August 30, 2018, 09:00 AM »
Will a T12 battery work in a C15?

What about the other way?

Will a C15 battery work in a SYS Light?

Will 18V Airstream batteries work in a C15?

  T12 in C15 , Yes.

  C15 in Syslite . Yes.

  Other way around , No.

  18v Airstream in C15, No.

       Lower works in higher.   Higher does not work in lower.

I'm surprised a 12 volt battery would work in a drill designed for 15 volts.

The Festool batteries / tools are designed to be backwards compatible and higher V tool with lower V battery.  At least within the same battery shape / style.  In fact the LiOn tools  will operate on a NiCd battery. Must be the electronics?

I am not certain this is true for all tools. But most I have tried are "keyed" to fit or not fit.

I have been running my 15v Impact on 12v (1.5 Ah) batteries and my TSC55 on 15v batteries.

One thing that doesn't work though is the TSC55 won't run on low Ah batteries even though the voltage is OK. EX- the 1.5Ah 12v and the compact  3.0 18v won't run the TSC55. Need to get over the 3.0 hump.
