Shipment and storage
Storage Conditions:
Storage times:
1. When moving batteries suitable mechanical handling aids
should be used. Never drag or roll the battery since
damage will be caused.
2. Do not touch the battery terminals or the safety valve
during handling.
3. The batteries are fully charged before shipment, do not
short circuit.
The storage area should be clean, dry and ventilated.
The battery should be stored away from any moisture ,
corrosive gas and source of heat.
The self-discharge of ABT TS/TM...W as a function of
temperature is as follows:
4. The batteries can be stored in an ambient where the
temperature range is -20 C to 60 C, but the maximum
storage time without charging is 6 months. If the storage
time is more than 6 months, the batteries must be
recharged at once.

In order to ensure that the battery can be charged easily
after a long period of storage, it is recommended that
batteries should not be stored for more than the following
periods without recharging:
6 months at 20
4 months at 30
2 months at 40

Failure to comply with these recommendations may
compromise the life expectancy of the battery. Determining
the state of charge of the battery.
The state of charge of the battery can be determined by
measuring the off-load voltage after the battery has been
allowed to rest for 24 hours.
Recharging stored batteries
The battery will be charged when the charging current has
remained constant for a period of 3 hours.
The batteries should be recharged at the float charge
voltage of 2.25~2.30Vpc at 20 C for a minimum period of
48 hours.
o
Maintenance
Check the tightening of connections.
A difference of plus or minus 2.0% between these
individual voltages and the average voltage may
be observed. This is due to the gas-recombination
process.
A check on capacity (independent operation on
load) can be performed once or twice per year.
New and old batteries cannot be used together.
The batteries of various specifications and from
different manufacturers cannot be used together.
Safety: When carrying out any work on the
battery, the applicable safety standards
should be followed.
Note: it is recommended that a battery log be
maintained, and that records should be
kept of the total voltage measurements,
any mains failures, major battery
discharges (current and time) etc.
The main factors causing reduction in the life
expectancy of ABT TS/TM Series cells:
Deep discharges
Poor regulation on the float voltage
Cycling or micro- cycling
Poor quality (smoothing) of the charging current
High ambient temperature.
Overcharge
Every month, it is recommended that the total
voltage at the battery terminals be measured. It
should be (NX2.25~2.30)V at a temperature of
20 C ,where N is the number of cells in the
battery,2.25-2.30 is the float voltage of each cell.

Installation of the battery
General recommendations
Do not wear clothing of synthetic material to avoid
the generation of static potentials.
Use insulated tools.
Consult the drawing for the correct position of the
cell poles (positive=red color, negative
= black color).
Before attaching the inter-cell flexible cables,
check that all terminals are in the correct position.
The battery cells are connected in series, which is
with a positive pole connected to a negative pole.
Use only a damp cotton cloth for cleaning
purposes.
