VALVE REGULATED LEAD-ACID BATTERY
RA/RT/EV/FT/DC/HR Series
1. Storage Environment
If batteries are not installed immediately after being received, please store them in a clean, ventilated and dark place at around
5~30℃.
2. Storage Time
Due to self-discharge, the battery capacity will lose gradually in storage. Do not store batteries for more than 12 months or the battery
performance will be affected eternally. After being stored for 6 months, batteries should be charged with a voltage of 2.35±0.02V for 24
hours and hereafter should be recharged at least once every 6 months. A relatively high temperature will accelerate the battery
self-discharge; from 20℃ when the temperature increases every 10℃, the recharging interval should be reduced by half. For example,
when at 35℃, the initial charging or recharging interval should be 3 months.
If a battery is not charged properly, its performance and life will be affected and cause the normal guarantee invalid.
1. Before touching the battery, please wear a rubber apron, rubber gloves, safety goggles or other eyes protection equipments; do not
wear metal objects, such as jewelry etc.
2. The battery is very heavy. Be careful and do not hit the battery when moving it.
3. Smoking or lighting fires are strictly forbidden. Keep the battery away from electric arc.
4. Avoid short circuit. The battery has been charged and please prevent battery from short circuit to avoid equipment damage or
personal injury.
5. Put the battery in a cool and well ventilated place. Do not install the battery in a place that is possible to be immersed by water.
6. Fix the bolts and nuts on the connection terminals to the specified orque; otherwise it may cause sparks or damages to the terminals.
7. Please clean the battery shell and cover with a wet cloth; to prevent static and spark, do not use any duster or dry cloth to clean the
battery. It's prohibited to use organic solvent such as rubber solution or naphtha, which will cause the battery shell cracking.
8. In normal operation, there will be no dissociative electrolyte on the shell after battery gets fully sealed. However, if the battery shell is
damaged, dissociative vitriol is possible to leak out. In case electrolyte splashes into eyes, and onto skin or clothes, flush it with a
large quantity of water. If it splashes into eyes, after rinsing with water, please get medical help promptly.
9. Make sure the positive (+/red) and negative(-/black)terminals are onnected properly, otherwise it will cause fire or damages to the
battery or charger.
10.Please use the following protection equipments when you carry, install and maintain the battery.
1）Safety goggles or protective face-shield; 2）Acid-resistant gloves; 3）Acid-resistant apron, safety shoes; 4）Proper carrying
instruments; 5）Insulation instruments.
11.Battery poles, terminals and fittings contain lead (or lead compound) and other chemical compositions, which are harmful to
health. Wash your hands after touching batteries!

1. Charge Characteristics
Charge condition is one of the important factors in battery use.
The battery performance and service life are directly related to
its charging methods and charging parameters in using.
The battery is recommended to be charged at the temperature range
of 5-30℃.At any temperature lower than 5℃ or higher than 35℃
it will cause undercharge or overheating and then decrease the
battery life.
2. Charge Curve of Float Use
3. Relationship between Float Charge Voltage and Environment Temperature
At general temperature (5℃~30℃), float charge voltage is 2.25V~2.30V. The batteries for float charge service
adopt the constant voltage but limited current method. The initial current is 0.1C A and the maximum current is 0.2 .
10
1) At 25℃, the float charge voltage of battery is 2.27V per cell.
2) When the ambient temperature changes, the float charge voltage should be adjusted. The temperature compensation
coefficient is -3Mv/, i.e., Ufloat =「2.27 – 0.003(t-25)」* n.
4. Equalize Charge
Equalize charge is required for float service as long time float charge will make some batteries drop behind in the battery
bank. An equalize charge can prevent battery stratification and reduce sulfation, which is the leading cause of battery
failure, and bring all cells to similar levels.
Equalize charge requirements for RITAR battery as follows:
※ Equalize charge 1 time every three months or every 20 discharge cycles.
※ Equalize charge method: with equalize charge voltage 2.35~2.45Vpc @25℃ and max. charge current 0.3CA, and
equalize charge time is 12~24h(when the charge current at the end stable about 2~3 hours, stopped equalize and switch
to float ).
※ Before equalize charge please let the battery 100% discharged.
5. Charge Curve of Cycle Use
The batteries for cycle service adopt the constant voltage but limited
current method. At 20℃~25℃, the charge voltage of battery is 2.40V
per cell; the initial charge current is not larger than 0.2C A and the
10
battery fully charges in approximately 24 hours.
Charge curves are as right.
6. Supplementary Charge

www.ritarpower.com
Due to self-discharge, the battery capacity reduces slowly in long
time storage. A supplementary charge is required prior to
installation. For the relationship of capacity, temperature and
storage time, please see the right curve figure. Apply supplementary
charge with constant voltage but limited current: charging current is
0.05C -0.2C ; charging voltage is 2.35±0.05V/Cell; charge time is
10 10
24~36 hours.
