The TIP31 is a commonplace medium power transistor. As pwdrive has said it's been strapped as a diode. A 1N4001 etc would have done just as well. If the LT is within range then leave it as is. Otherwise Trevor's suggestion of a cyclon is a good one. Actually any 2V lead acid cell would be fine though not as long lasting and tough as a Cyclon.
