  calorimeter in which to do combined thermal (and pressure) and electrical measurements. These have included cycling, shorting and overvoltage. There are many other abuse tests that safety procedures and regulations request – one of these is Nail Penetration; internal shorting. The prescribed methods detail varied nail sizes and penetration speeds and the result is typically… are flames seen or not. Carrying out such a test within a calorimeter will give an extra dimension on the result. It will quantify the heat released in terms of temperature rise and will determine if the heat released on shorting leads in to other catastrophic reactions causing battery disintegration. It is illustrated here how the ARC can be used with simple modification to allow nail penetration tests to be performed. In the tests described the nail penetration has been achieved manually. An automated option is available from THT and there is also (not reported here) the possibility of simultaneously measuring battery voltage.
