| Battery operating time |
One rechargeable lithium polymer: 13 hours (typical) |
| Year of manufacture |
The detector's year of manufacture is determined from the serial number. The second and third number after the second letter determines the year of manufacture. E.g., MA 110-000001 = 2010 year of manufacture |
