b) Trickle (Float) life
Trickle life of the battery is largely dependent on the
temperature condition of the equipment in which the
battery is used, and also related to the type of the
battery, charge voltage and discharge current. The
respective Figures show the influence of temperature
on trickle life of the battery, an example of trickle
(float) life characteristics of the battery, and the test
result of the battery life in an emergency lamp.
