What are the recommended float and equalize voltage ranges for
the different cell types? How should they be adjusted for
temperature?
- FLOAT:
- Absolyte IIP:
2.23 - 2.27 volts per cell at 25 �C
Vcorrected
= V25 C - [0.0055 V/ �C x (Tactual - 25 �C)]
Do not adjust
below 2.20 volts per cell or above 2.35 volts per cell.
- Absolyte XL:
2.23 - 2.25 volts per cell at 25 �C
Use same
formula as above for temperature correction
Do not adjust
below 2.20 volts per cell or above 2.35 volts per cell.
- Lead calcium:
2.17 - 2.25 volts per cell (1.215 specific
gravity)
2.23 - 2.33 volts per cell (1.250 specific
gravity)
- Lead antimony:
2.15 -- 2.17 volts per cell (1.215 specific
gravity)
2.19 - 2.23 volts per cell (1.250 specific
gravity)
- Marathon/Sprinter:
2.25 - 2.30 volts per cell
Use same formula as
above for temperature correction.
- EQUALIZE: (times listed below are for after charging current
has tapered and stabilized)
- Absolyte IIP:
2.30 volts per cell (at 25 �C) for 24
hours
2.35 volts per cell (at 25 �C ) for 12 hours
Use
same formula as above for temperature correction.
Do not
adjust below 2.20 volts per cell or above 2.35 volts per cell.
- Absolyte XL:
Same as Absolyte IIP
- Lead calcium:

number of hours.
- Marathon/Sprinter:
2.35 volts per cell (at 25 �C) for 24
hours

Given a required constant current/power discharge, end voltage,
and duration, what cell type is necessary? Given a certain cell
type, constant power/current discharge, and end voltage, what is the
back-up time?
Locate the correct amp/watt data table for the end voltage you
are using. Locate the appropriate column for the required back-up
time. Read down until you find the current/power you are looking
for then read straight across to the left for the cell type.
For batteries with complex load profiles, sizing should be done
per IEEE-485. Please consult Support Power, Inc., we will
calculate the appropriate GNB cell size per IEEE-485 and provide
you with a copy of the cell sizing worksheet.
To determine back-up time locate the correct amp/watt data
table for the end voltage you are using. Next, locate the cell
type you have and read straight across to the required amp/watt
value then straight up for the back-up
time.
Questions about acid/electrolyte quantities for reporting
purposes.
These types of questions should be forwarded to Support
Power at 631-218-0876.

What is GNB's equivalent to a competitor's battery? What is
GNB's current equivalent to an old GNB cell?
Oftentimes, it is possible to determine equivalents by
comparing the product literature (cell size, amp-hour rating,
discharge characteristics). If this is not possible, please
contact Support Power, Inc. at (631)
218-0876.
What is the list price for a particular part?
Please contact Support Power at (631)
218-0876.
How can I obtain a brochure or Installation & Operating
Manual for a particular cell?
Please contact Support Power at (631)
218-0876.
What are the space considerations for Absolyte IIP?
There should be a minimum of 4.5" between the stack and the
wall and between back-to-back stacks. A minimum of 36" aisle space
should be available adjacent to the battery system.
Also note, allow at least six inches past total system length
wherever a terminal plate assembly is to be
located.
How does temperature affect batteries?
As a rule of thumb, for each 10 �C above 25 �C, the battery
life is halved. At temperatures below 25 �C, the capacity is
reduced according to the following table:
Temperature |
Percent capacity |
25 �C |
100% |
20 �C |
95% |
15 �C |
90% |
10 �C |

What is end voltage? What is the difference between a high and
low end voltage?
End voltage is the voltage of the cell (or battery) at the end
of the duty cycle. End voltage is usually selected based on the
duration of the discharge and the minimum system voltage the
equipment can tolerate. For long duration discharges (12+ hours),
it is recommended that a high end voltage be used (1.90+ volts per
cell). For short duration discharges (< 90 min.) such as UPS
systems, a low end voltage is used (e.g. 1.67 volts per cell). For
normal duration discharges (90 min to 12 hr), an average end
voltage (e.g. 1.75 volts per cell) should be
used.
Who should I call for GNB battery recycling information?
For more information on GNB's lead-acid battery recycling
program please call:
What is the difference between the Absolyte's AGM technology and
gel cells?
To immobilize the electrolyte in a gel cell, the electrolyte is
mixed with fumed silica then the cell is filled while the mixture
is still liquid. In time, the mixture gels similar to what one
observes with "Jello".
In GNB's Absolyte cells, the electrolyte is absorbed in the
glass separators (similar to a sponge).

particular cell?
