1 Caution/warning statements
1.1 General safety signs
Symbol
Meaning
Prohibition symbols are circular, showing a
black pictogram on a white background
surrounded by a red edge with a crossbar.
Warning signs are triangular, showing a black
symbol and edge on a yellow background.
Environmental regulations are information on
statutory requirements, which have to be
complied with, especially during disposal.
1.2 General hazard sources
If the following instructions for handling the device are not observed, this might lead to personal injury
or damage to the battery or your device, for which VARTA Storage GmbH will accept no liability.
a. Danger of electrical voltage
WARNING
Contact with electrical voltage!
Risk of fatal injury from electric shock!
Keep the module always sealed.
Pay attention to any damage of electrical
equipment! Eliminate defects immediately!
Don´t open the module.
Don’t connect the modules in serial only in
parallel.
Don´t connect the module or charger in reverse
polarity.

5
You are not allowed to disconnect the module in
active mode. Hot-plugging or hot-swapping is not
allowed in active mode! There is a risk of short
circuit between the battery modules. Only in shut-
down mode old or damaged modules can be
replaced with new modules. Even modules with
new cell chemistries are supported if available in
the future.
b. Danger from water
WARNING
Entry of water or other liquids into the module!
Possible mortal danger and material damage!
Do not use water for cleaning the module.
Never put down containers with fluids (beverage
containers and the like) on electrical systems.
The relative humidity inside the room must not
exceed 85%.
Do not clean the system with agents containing
acid, lye or solvents.
c. Danger from heat
ATTENTION
Insufficient ventilation of the system!
Overheating of the system possible!
Keep the ventilation openings clear.
Ensure sufficient ventilation.
ATTENTION
Heat input due to direct sunlight or devices emitting
heat!
Overheating and damage of the system possible!
Protect the system against direct sunlight.
Do not use fan heaters or the like near the
module.

1.3 Safety Overview on Battery Management System (BMS)
The battery contains three levels of safety, which is controlled by the BMS.
1st Level Protection for over voltage/ under voltage / over current / short circuit / over temperature /
under temperature. It is controlled by the BMS software and is non-permanent.
2nd Level Protection for over voltage/ under voltage / over current / short circuit / over temperature/
under temperature. It is controlled by the BMS software and is permanent.
3rd Level Protection (passive) with current fuse on board.
1.4 Certification
The battery is qualified acc. to UN Recommendations on the Transportation of Dangerous Goods, UN
Manual of Test and Criteria, Part III, subsection 38.3 (ST/SG/AC.10/11/Rev. 5). The battery is qualified
acc. to IEC 62133-2:2017.

3 Introduction of ASB
Application Specific Batteries (ASB) is VARTA’s new range of lithium-rechargeable battery products
from VARTA Storage GmbH, offering products in the voltage range of 24V –48V for modern systems
and applications.
We offer a growing range of battery packs that are immediately available for high-energy or high-
power applications. All ASB battery packs are fitted with an electronic battery management system
(BMS) with protection against unsafe conditions. All cells used comply with the requirements of the
safety standard UL1642 and the packs in this handbook are certified to additional safety standard
IEC62133-2:2017 as well as UN38.3 requirements for transportation.
SYSTEM HIGHLIGHTS OF VARTA STORAGE ASB RANGE:
►Excellent energy density
►Zero maintenance requirements
►Different form factors
►Low self-discharge and wide temperature
range
►~24V and ~48V versions
►Up to 40kWh systems using modular
approach
►IEC62133-2:2017 certification
►Mechanical stacking/locking design
►CAN Bus Communications (CANopen)
►ISO9001 certified for design and
manufacture
►Excellent cycle life (see PI-Sheet)
►2 year manufacturer’s limited warranty

3.1 Definitions and Standards
BASICS
Unless otherwise stated the technical values and definitions are based on room temperature
conditions (RT = 22°C ± 3°C).
VOLTAGE DEFINITIONS
Open Circuit Voltage (OCV):
is the difference of electrical potential between
two terminals of a device when disconnected from
any circuit, dependent on battery model,
temperature, storage duration and state of
charge.
End of Discharge Voltage (EoD):
The voltage at the end of discharging depending
on discharge rate and temperature.
End of Charge Voltage (EoC) should also be
referenced from the individual specifications.
CAPACITY DEFINITIONS
The capacity C of a cell is defined by the
discharge current I and the discharge
time t: C = I * t
I = constant discharge current
t = duration from the beginning of discharge until
the end of discharge voltage is reached
Nominal Capacity: The nominal capacity C
denotes the capacity amount in Ah (Ampère
hours) that the battery can deliver at the 5h
discharge rate (0.2 C). The reference
temperature is +22°C ± 3°C, if not otherwise
stated and the final discharge voltage will also be
stated.
Available Capacity:
Factors which affect the available capacity are:
►Rate of discharge
►End of discharge voltage
►Ambient temperature
►State of charge
►Battery age
►Cycle history of the battery
At higher than usual discharge rates the
available capacity is accordingly reduced.
CURRENT DEFINITIONS
Charge and discharge rates may be given as
multiples of the Rated Capacity (C) in Ampères
(A) with the term C.
Example:
Rated Capacity C = 1000 mAh
0.1 C = 100 mA, 1 CA = 1000 mA
Nominal Discharge Current:
The nominal discharge current of an ASB battery
is the 5 hour discharge current (0.2 C). It is the
current at which the nominal capacity of a cell is
discharged in 5 hours.
I = C/t = C/5 = 0.2 C when t = 5 h

3.2 General Design and Application Criteria
Choose the best suitable battery from our range of ASB batteries according to your needs relating to
the specific application and its corresponding planned operation conditions:
The most important criteria for the type-selection are these:
►Required minimum operating time
►Charging rates required vs. calendar life target
►Max. and average current drain
►Min. and max. voltage of operation
►Operating temperature range
►Mechanical properties
►Available space
►Environmental conditions
All ASB batteries are equipped with our specially selected and carefully designed safety electronic
modules (BMS) which prevent the risks of hazards due to any foreseeable abuse / misuse.
Nevertheless, it is required that any application is designed so that the battery may operate within its
normal specification without the safety features being triggered by end-user behavior.
3.3 Features
VARTA Storage ASB batteries are first choice for a number of modern high-tech products in fields
such as robotics, Automated Guided Vehicles (AGV), related Logistics and Agricultural solutions and
more. They provide long lasting, reliable main power, occupying a minimum of space and weight in the
corresponding devices.
VARTA Storage ASB batteries fulfill the most important design-in requirements: Reliable high-power
output, design flexibility with minimized space requirements and a long life.
