4.3.1 AC Chargers
AC Float chargers provide constant charging of the iSIC battery. It connects to an electrical
outlet near the data logger and provides constant battery life for high power consumption
sensors. If an electrical outlet is located near the iSIC data logger, it is recommended that a float
charger be used.
For outdoor use, a power outlet cover can be purchased to protect the charger from rain and
other related weather wear and tear.
A light on the outside of float charger lets you know if it is active. While the LED is orange the
battery is charging, while green the battery is fully charged, and if the light is red or not on then
there is a problem with either the A11 charger or the AC outlet. Try plugging another AC device
into the outlet to make sure it can supply power. Then try the float charger in a different outlet.
If you the A11 float charge will be installed on an outdoor outlet, NexSens recommends an A15
Deep Outlet Cover which will weatherproof the outlet and float charger.
A15 Features:
 For use with the A11 battery charger
 Weatherproof construction
 Mounts with standard 110 VAC receptacle faceplate
Note: Due to the self-discharge characteristics of lead acid batteries, it is imperative that
they be charged after 6-9 months of storage, otherwise permanent loss of capacity might
occur as a result of sulfation. If disconnecting the AC Charger for winter removal, etc, make
sure to charge the battery if the system will be stored for 6-9 months or longer.
