Operating Characteristics
Voltage
Float Charge
The nominal voltage is 2 volts per cell, i.e. a nominal 110V
battery will have 55 cells. On discharge, the recommended final
voltage at which the discharge should be terminated depends
on the discharge rate. For example, the final voltage for the
three hour rate of discharge is 1.80 volts. After final voltage has
been reached, the voltage will fall away at an increasing rate.
Constant voltage float charging at 2.25 volts per cell will
maintain full capacity with minimal water loss. Lower float
voltage levels may be used but must be complemented with
regular freshening charges. A simple hydrometer reading
indicates the state of charge. A fully charged cell will have a
specific gravity in the range 1.205 to 1.215 at 15°C.
Capacity
Recharge
The capacity which can be taken from a cell varies with the
discharge rate as indicated in the capacity tables. Capacity is
also affected by temperature.
A YHP 11 cell discharged at the 1 hour rate (300 amperes for
1 hour) will require a minimum of 300 +11%, i.e. 333 ampere
hours recharge. At the finishing rate of charge (7% C10 amperes)
this will take 91/2 hours.
Trickle Charge
Trickle charging is a method of keeping the cells in a fully
charged condition by passing a small current through them.
The correct trickle charge current is that which neither allows the
cell to gas nor the gravity to fall over a period of time. It is
normally in the region of 1 milliampere per ampere hour of the
10 hour capacity for YAP cells, and 0.3 x capacity at the 10 hour
rate + 70 milliamperes for YCP and YHP cells. With this small
current flowing, the cell voltage will be approximately 2.25 volts.
www.enersys.com
It is possible to recharge in a shorter time by starting the charge
at the ‘starting rate’ (14% C10 amperes) but this should be
reduced to the finishing rate of charge when the voltage per cell
reaches 2.3 volts.
On recharge, the voltage increases as the charge proceeds.
The highest voltage reached with the finishing rate of charge
flowing is approximately 2.70 volts per cell. It is possible to
recharge a cell by limiting the voltage of the charging equipment
to a lower value than 2.70 volts per cell, 2.4 volts per cell being
the minimum recommended value. This will result in an
extended recharge period, as the battery will automatically limit
the charge current irrespective of the charger output.

Notes:
The suffixes 'E' and 'F' refer to the layout of the cells on the stand:
• the suffix 'E' signifies that the cells are arranged with the plates edge to
edge
• the suffix 'F' signifies that they are arranged with the plates face to face
Calculating other lengths of stands:
- For Double tier single row length = C x N/2 + 25mm
- For Double tier double row length = C x N/4 + 25mm,
where C = cell centre and N = number of cells
If N/2 or N/4 contains a fraction, increase to next whole number.
