Silent Knight does not support the use of batteries smaller than those listed in Table 3-4. If you use a battery too
small for the installation, the system could overload the battery resulting in the installation having less than the
required 24 hours standby power. Use Table 3-2 to calculate the correct battery amperes/hour rating needed for
your installation. It is recommended that you replace batteries every five years.
