CHARGER FEATURES
GENERAL
The standard ES3 charger has a wide range of charging features for both flooded and sealed cell batteries. The ES3 is
capable of charging various cell sizes and ampere-hour ratings as listed on the charger nameplate. Some of the basic
features are described below.
DATA LOGGING
A new feature is the data logging of charge cycle parameters such as total charge time, amp hours returned, maximum
charger voltage etc. Charge data is held in non-volatile memory for up to 1000 cycle incidents. After 1000 incidents, the
charge counter rolls over.
CHARGE PROFILE OPTIONS
The ES3 is capable of charging sealed or flooded batteries under a variety of conditions. Multiple profiles, such as
Flooded, Sealed, Opportunity and Automatic Guided Vehicle are only some of the charge profiles the ES3 is capable of
delivering to the battery. Multiple termination and finish selections will provide the customer with the perfect charge to fit
their battery needs.
LCD DISPLAY
A bright, 2X20 large character LCD display provides large and easy to read text messages and data throughout the
charging cycles. Multiple settings let the user choose their preferred contrast and type of information they wish to display.
REAL TIME CLOCK/CALENDAR
The ES3 features a real time clock and calendar. The current time and date is displayed and the time/date information can
be used for charge cycle control. A super capacitor enables the control board to retain the time and date information for
up to one week during AC power outages.
AUTO CELL SIZING
The ES3 can charge any battery from 1 to 40 cells. Automatic cell sizing is limited to specific common cell sizes shown
below. The range of battery cell sizes that an ES3 charger can automatically select is shown in the following table.
Charger Nameplate
Rating
Automatic Battery Cell Select Range
40 cells 40,32,24,18,12,6
32 cells 32,24,18,12,6
24 cells 24,18,12,6
18 cells 18,12,6
12 cells 12,6
After detecting a battery, the ES3 will go into a two minute test charge phase, followed by a two minute rest period. The
ES3 then automatically determines the battery cell size based on the voltage response of the test charge.
MULTIPLE BATTERY SELECT
A total of 3 completely different battery profile selections can be stored and quickly selected for the customer that has
multiple battery cell sizes and amp-hours. Used in conjunction with auto cell sizing, the ES3 charger can automatically
choose between batteries with different cell sizes, amp-hours and profiles. The default for the charger is to have this
feature shut off so that only a single battery selection can be made.
