NOTE
: Every time a chemistry is selected, all learning is lost, even if you
re-select the currently used chemistry. This will mean that the SG200 will
need a few charge cycles to obtain peak accuracy.

CAPACITY - Selecting a Battery Design Capacity
Once you select a chemistry, you must specify the capacity of the battery
bank. This is the total design capacity of the entire bank, regardless of the
battery’s condition, or previously measured capacity. Typically the capacity is
expressed as the 20-hour discharge rate. This may be written as something
like “105Ah/20h” on the battery or battery documentation. If you cannot find
an Ah specification for your battery, but it does show a reserve capacity (RC)
refer the Appendix “Converting Reserve Capacity to Amp Hours.” CCA or
MCCA values are not describing capacity and cannot be used to determine
the battery capacity.
EXAMPLE
: Consider three Group 31 batteries, each with a design
capacity of 100 amp hours. They are connected in parallel to make
a 12v, 300Ah bank. The design capacity to be entered is 300. Even
if the batteries are older, and they have diminished in capacity, the
bank capacity should always be entered as a design capacity.
To set the capacity, use a short press to highlight the digit to be changed.
Once it is highlighted, a long press will allow you to edit that digit, then a short
press to increment the value up When you have that digit set to the correct
number, another long press will exit the edit mode for that digit, and move
to the next. Do the same for all digits that need adjusting. When the value is
correct, move the highlight to DONE on the bottom menu bar and perform
a long press. The design capacity is now saved. If the design capacity is
changed at any time, the system resets and any battery learning (described in
“Initial Accuracy”) is lost.
Note
: Do not artificially lower the design capacity to account
for a perceived pre-existing loss in capacity. The SG200
relies on the design capacity data being correct.
CHARGING - Charge Termination and Charge Efficiency
The CHARGE VOLTAGE and TAPER CURRENT are used together by
the SG200 to determine when charge
termination has occurred. This is
indicated on the Display when a “+” sign shows on the SoC Display. Charge
Termination is defined as when the battery is fully up to 100% of it’s present
capacity. Each of these values have defaults that are set per chemistry, but
can be changed if required.
Selecting the CHARGING menu item brings up a sub menu, where the follow-
ing options can be set:
