Abstract
Provided herein is a battery module for starting the engines of outdoor power equipment such as automobiles, boats, trucks and tractors. The battery module disclosed herein has high performance at low temperature and has a maximum pulse discharging current measured at −30° C. of not less than 15% of the maximum pulse discharging current measured at 25° C. over a pulse discharge period of about 5 seconds. In addition, the battery module disclosed herein has a low self-discharging rate at both room temperature and high temperature. The capacity retention of the battery module is not less than 85% of its initial capacity after 7 months of room temperature storage.
