Maintenance-free back-up (stationary) accumulator, type:

AGM (VRLA design: valve-regulated lead-acid battery with

absorbed electrolyte – suitable for alarms, UPS, auxiliary

power units, emergency lighting, telecommunication, etc.)

This manual describes how to put the individual types of

batteries (accumulators) into operation and also describes their

maintenance, safe handling, storage and disposal.

Important warnings:

• Every battery (cell, accumulator) is a chemical power

source containing solid or liquid chemical compounds

(corrosive substances) that may damage health, property

or the environment. Handle batteries with caution.

• When ready for use, the accumulator is capable of supplying

electrical current at any time, even under undesirable cir-

cumstances! Even if the battery is only partially charged,

interconnecting both contacts (terminals) with a conductive

material (e.g. by careless handling, transport, storage etc.)

will result in an uncontrolled release of a large amount of

electrical energy, i.e. a SHORT CIRCUIT. At best, this will only

damage the battery. It worst, if the short circuit is long-term

(but even a few seconds are enough), it may cause re or

even an explosion, resulting in property or environmental

damage, injury and potentially loss of life! Always handle

batteries in a way that prevents short circuits!

• Used batteries or old unused batteries, functional and

non-functional batteries and cells automatically become

hazardous waste once depleted. Improper disposal may

seriously endanger the environment! In the vast majority of

cases, batteries contain hazardous chemical elements or

compounds: lead, cadmium, mercury, electrolyte (H2SO4)

and other poisonous substances harmful to human health.

Improper storage may release these substances into the

environment and cause contamination. Please do not dis-

pose of depleted batteries and cells as communal waste!

We will take back any used accumulators or cells FREE

OF CHARGE from you and ensure their proper recycling or

disposal. In accordance with the Waste Act, every munici-

pality is obligated to arrange the establishment of collection

points where citizens can bring hazardous components of

communal waste. You can also bring in used batteries and

cells to shops that sell new ones.

• Individual accumulator types greatly dier from one ano-

ther. When changing an old battery for a new one, it is

necessary to follow the instructions of the manufacturer

of the device (auxiliary power unit – UPS etc.) which state

which type of accumulator is suitable for the appliance in

question. Installing an unsuitable type of battery can cau-

se irreversible damage to the device. Such cases are not

covered by the warranty on the part of the supplier of the

replacement battery, nor on the part of the manufacturer

of the appliance.

a) Description

As the name suggests, VRLA batteries (valve-regulated

lead-acid batteries) regulate the release of gas by a valve. In

practice, this means that there is almost no leakage of aerosols

from the H2SO4 electrolyte. The valve prevents gas leakage

and can handle overpressure of up to 0.43 kPa. The battery

is based on lead and electrolyte bound in glass microbres

(so-called AGM – absorbent glass mat) or, more rarely, in gel

(containing electrolyte thickened by thixotropic gel – SiO2).

AGM back-up batteries are commonly used in devices such as

UPS, electrical re alarm systems, electrical security systems,

emergency lighting, telecommunication, but also as a power

source for electric motors (scooters, children‘s toys and many

other appliances).

b) Maintenance, Storage and Handling

AGM-type stationary batteries are fully maintenance-free.

However, basic rules have to be followed during their use to

prevent shortening of their service life. Operating conditions

are very important, particularly ambient temperature. Optimal

operating temperature provided by the manufacturer is 20 to

25 °C. Exceeding these values long-term or frequently will

dramatically shorten the service life of the battery. Extremely

high operating temperatures may even result in irreversible

damage. If the battery is subjected to long-term exposure to

operating temperatures above 40 °C, all chemical processes

are accelerated, resulting in increased release of gas and thus

increased pressure inside the cell. In such circumstances, the

valves can no longer regulate the pressure and the accumula-

ting gas is not released at a sucient pace. The accumulator

heats up and the plastic casing deforms and increases in volume

(literally inates). The service life of AGM batteries as stated

by manufacturers, provided optimal operating conditions are

observed, is between 4 to 12 years depending on model. AGM

technology is very eective in reducing self-discharge. While

classic ooded batteries self-discharge at a rate of approxi-

mately 1 % of their capacity a day, AGM batteries discharge

approximately 1–3 % a month (i.e. a maximum of 0.1 % a day)!

This naturally increases their shelf life. Handling and operation

of back-up batteries only requires following basic principles

of battery use. The battery can be operated in any position.

However, operating the battery in upside down position is the

least suitable and is not recommended. The battery must not be

stored or operated in the vicinity of open ame. Fall from height

or heavy blows can cause irreversible mechanical damage.

The terminals of the battery must not be interconnected with

one another during operation, handling or storage to prevent

short circuits. A short circuit may damage the battery, cause

a re or an explosion, resulting in injury or even death. If the

casing of the battery sustains mechanical damage, electrolyte

(corrosive substance) may leak out of the battery and come

into contact with the skin. Immediately wash any aected skin

areas with water and neutralise with soap or soda. In the event

of more extensive contact or acid burns, seek medical attention

as soon as possible.

c) Charging

Before beginning the charging process, check the rated voltage

of your battery. The battery must be charged by a suitable

power source or charger with charging voltage of 14.4 V for 12

V accumulators and 7.2 V for 6 V accumulators. If the charger

or power source does not meet these parameters, the battery

will not be charged fully, which will result in its quick depletion

and, in extreme cases, destruction. Complaints regarding these

negative eects will not be accepted. Also check that your

charger is suitable for charging the given type of accumulator

(AGM, GEL) and has the correct rated voltage. Last but not

least, check that the charger is suciently powerful to charge

your accumulator or that it is not too powerful and thus also

unsuitable, since its charging current is too high.

Charging accumulators is not dicult. Here are simple guideli-

nes to follow. If you are still unsure after these instructions, it

is always best to consult a professional ahead of time or have

them charge the accumulator for you. You can also use the

manual that came with the charger.

Some sections of article c) describe situations that are irrele-

vant to users of automatic chargers. These chapters are marked

with an asterisk *.

• Accumulator type – we will be describing the charging of

AGM or GEL maintenance-free accumulators.

• Correct voltage – make sure your charger is set to the

correct rated charging voltage. Charging voltage must be

14.4 V for 12 V batteries and 7.2 V for 6 V batteries. Some

chargers do not have a switch. In that case, simply check

whether the data on both components matches (e.g. 12 V

charger and 12 V batteries).

• Correct polarity – before starting the charger, check that

the poles on the battery and the terminals on the charger

cables match, i.e. connect the negative terminal to the

negative pole and positive terminal to the positive pole.

Otherwise you risk a short circuit.

• Ventilation – check that the ventilation (valve vents on the

battery lid on top or on the side) is clean and unobstructed

and that gases can freely release from the battery if nee-

ded. If the vents are clogged or covered, there is a risk of

accumulation of gases inside the battery, causing potential

irreversible damage. Some batteries do not feature vents

or the vents are hidden.

• Setting an automatic charger – if the charger features

multiple setting options, follow the instructions provided

by the manufacturer of the charger. Usually the charger

allows setting charging voltage and current. You will nd

instructions on the required charging current in the next

paragraph. If the charger has no settings, start it up by

plugging the power cable into a 220 V (230 V) mains socket;

the cables with terminals should already be connected to

the battery poles at this point.

• Charging current* – general rule of thumb: charge with

current equal to one tenth (1/10) of battery capacity. Expre-

ssed numerically, if you have a 60 Ah accumulator, charge

it at 6 A (60 : 10 = 6 A). There is a more accurate charging

formula that states that the charging current should equal

0.12 times the accumulator capacity. I.e. I = 0.12 × C. In

practice, if you have a 60 Ah accumulator, then 60 × 0.12

= 7.2 A charging current.

These days, most users have automatic chargers. In that

case, simply choose a suitable charger with sucient

current. Take into account, however, that charge time is

directly proportional to charging current. Charging should

not take unnecessarily long (1 A charging current is too

little for a 60 Ah battery, for instance). Vice versa, do not

choose a charger that is too powerful, so that charging

isn‘t unnecessarily fast. Such charging is harmful to the

accumulator in the long term (e.g. charging current over

14 A is too high for a 60 Ah battery).

Note: if your charger allows adjusting the charging current,

charge according to formula I = 0.12 × C up until you reach

voltage of 14.2 V; then, reduce the current to half and con-

tinue until charging is complete (voltage will reach 14.4 V).

• Signs of full charging* – in general, a battery should

be recharged to full charge. Maintenance-free batteries

without caps or AGM batteries with absorbed electrolyte

no longer allow measuring energy density; do not under

any circumstances attempt to break into the battery! The

state of charge of a 12 V maintenance-free AGM or GEL

type lead-acid battery, charged in a standard way with a

manual charger, can be estimated by measuring voltage

on the poles during charging. The values can be interpreted

as follows: 14.3 V = 90 to 95 % charge, 14.4 to 14.5 V =

100 % charge.

WARNING – make sure to correctly set the measured

quantity on the measuring device to voltage [V].

• Quick charging* – In exceptional cases where quick charging

is necessary, it is possible to use a charging current of I = 1 ×

C (in our example of a 60 Ah battery, charging current would

be 60 A). However, only charge this way for a maximum

of 30 minutes! Keep in mind that the more frequently you

use higher charging currents to recharge your battery, the

shorter you can expect the service life of the battery to be.

• Accumulator capacity – the current capacity (state of

charge) of the accumulator can be determined using simple

measuring devices. You can use both devices for approxima-

te measurement without putting a load on the accumulator

and more precise devices that measure internal resistance.

However, precisely determining the service life of the

accumulator requires a complex diagnostic process using

an expensive testing device that discharges and recharges

the accumulator. Such diagnostic can take several hours

for smaller batteries and several days for larger batteries.

It is recommended to do any testing to determine battery

capacity only with a fully charged accumulator and with at

least 4 hour gap since last charging. Approximate measu-

rement of capacity can be done using a simple measuring

device called a voltmeter. Measure without load, i.e. only

measure voltage without current drain. Compare the mea-

sured values with the following table (note: the results of

measurement may be misrepresentative or completely

incorrect for damaged batteries or older batteries that have

been used for a long time; such batteries can be identied

and tested only using more complex methods):

State of charge Measured voltage

100 % 12.90+ V

75 % 12.60 V

50 % 12.40 V

25 % 12.10 V

0 % 11.90 V

• Deep discharge – if you discharge the accumulator com-

pletely and leave it in this state for several days, you will

reach a state of so-called deep discharge; measured volt-

age at zero load will drop under 11 V and a process called

sulphation will begin inside the cells. The sulphur originally

contained in the electrolyte will „seep“ into the active

material of the lead plates due to discharging. Recharging

would once again „dislodge“ and mix the sulphur with the

diluted, watery electrolyte, increasing the concentration of

the acid. But when not recharged, the sulphur reacts with

the lead, resulting in further oxidation and the active lead

material turns into lead sulphide, also known as sulphate.

In advanced stages, the process is irreversible and the

accumulator is permanently damaged. If the accumulator

reaches a state of deep discharge, it is often no longer

rechargeable using a standard automatic charger. These

chargers are usually either unable to detect the voltage in

the discharged battery and will not start charging at all, or

they start charging but are unable to overcome the internal

resistance of the sulphated accumulator and overheat.

To try to restore the accumulator, bring it to a professional

service centre. Deeply discharged accumulators that have

become damaged in this way are not covered by the wa-

rranty.
