Battery2go Battery fit to HILTI SID 144-A CPC Impact Driver, SF 144-A CPC 14.4 V

6/8/2016 Update: Buyer beware... The battery did not last long and seller offered no help.I purchased this battery as a spare two years ago and did not use as I haven't used the Hilti driver as much as I used to. Much to my surprise I found that beyond the initial test charge/run I did when it first arrived, this battery is DoA... The battery will no longer accept a charge, the left LED ((right LED when battery not inverted in charger) blinks then shuts off. I attempted to contact the seller but they hid behind a lapsed warranty, no discount on replacement or any assistance at all. Makes me think twice about saving a relatively small amount over the OEM alternative.8/1/2014 This was much larger than what I was trying to replace but the extra amp hrs are nice to have... love Hilti products and was a little surprised that the original mysteriously failed completely dead/no recharge after 5 years.
