Dear  Mr.   Farrar:

This is in response to your letter of February 10, 1999, requesting clarification on the requirements for lithiurn batteries under the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180).
Specifically you ask whether a 32 volt lithium battery must be subjected to the tests in the UN Manual of Tests and Criteria, specifically paragraph

The answer is no.  A lithium battery that exceeds the referenced nominal voltage is not subject to those tests.  Such a battery would have each cell tested rather than the entire battery.

I hope this information is helpful.
