Battery Lead Connections are not power limited.
Before installation:
New Batteries may require ‘top charging’ prior to being put into service. Refer to
battery manufacturer information for confirmation of this requirement. For further
information and for a list of recommended batteries, refer to Appendix 4, Section 1.3.
Ensure the thermistor is affixed to the sidewall of one of the batteries, using a suit-
able silicon sealant.
