WARNING
Misuse of the RETRON BOX poses a risk to life!
The manufacturer shall not be held liable for any inappropriate use of the box. Misuse will invalidate the
guarantee and warranty.
1.4 RESIDUAL RISKS
The RETRON BOX has been developed and constructed in strict compliance with the relevant standards and
legal requirements. The current standards relating to technical development and safety have been met. Even if the
RETRON BOX is used appropriately, its use still presents a number of residual risks, in other words unavoidable
dangers. These dangers are outlined in this user guide.
2. TECHNICAL DETAILS
Dimensions (L x W x H)
External: 520 mm x 427 mm x 205 mm
Internal: 460 mm x 360 mm x 155 mm (usable height)
Weight: 9 kg
3. HOW IT WORKS
In certain circumstances (for instance if there is a short circuit within the cells), there is a risk that lithium ion
batteries could themselves ignite. The resulting ames can reach temperatures of over 1200 °C. These ames
can very rapidly cause surrounding objects to catch alight. In most cases it is then impossible to stop the re from
spreading. It is also impossible to stop a considerable volume of gas from forming.
These gases are highly poisonous and corrosive and must not be inhaled under any circumstances. If lithium ion
batteries ignite explosively, fragments of the battery or casing may shoot through the air, causing considerable
personal injury and damage to property.
The RETRON BOX makes for an ideal method of re prevention by oering ame protection. If lithium ion
batteries are stored, transported or charged inside the RETRON BOX, the risk of potential ignition spreading to the
surrounding area is signicantly reduced. In addition, the RETRON BOX provides protection from ying fragments
of the battery and casing. The RETRON BOX is unable to prevent the spread of gases. However, poisonous/
corrosive parts of the discharging gas will be partially ltered out by the RETRON cushions in the RETRON BOX.
The RETRON cushions are also ame retardant and absorb any electrolyte that may leak out.
WARNING
Risk of poisoning and risk to life due to the inhalation of gases formed during combustion!
Do not inhale gases under any circumstances!

6. OPERATION
When storing and transporting lithium ion batteries, the battery or batteries must be placed in the RETRON BOX
between the two RETRON cushions. The RETRON cushions are ame retardant and protect the batteries inside
the box from shocks and shaking.
WARNING
When charging batteries, only use one cushion at the bottom of the box and position the batteries on top. Do not
cover the batteries before closing the lid. This will ensure that any heat produced during charging will be dissipated
eciently.
WARNING
Risk of poisoning and risk to life due to the inhalation of gases formed during combustion!
WARNING
Risk to life due to closing o the ame-retardant grille!
The rear openings on the ame-retardant grille of the RETRON BOX must not be modied in a way that closes o
or seals them either from the inside or the outside!
6.1 INSERTING THE BATTERIES
1. Move the lever of the snap locks into the ‘open’ position and remove the lid.
2. Place a RETRON cushion (supplied) inside the RETRON BOX so that it ts snugly on the base of the box.
3. Place the battery or batteries on the RETRON cushion at the bottom of the box.
4. When using the box for storing and transporting, place the second cushion on top of the battery or batte-
ries so that the battery or batteries are sandwiched between the cushions.
5. Do not use the second cushion in the box when charging!
6. Place the box lid on top.
7. When locking the RETRON BOX, make sure that the RETRON cushions are not caught in the locking
mechanism or between the main body of the box and the lid.
8. Engage the snap locks by moving them into the ‘closed’ position.

6.2 STORING AND TRANSPORTING BATTERIES IN THE RETRON BOX
The RETRON BOX is a securely sealed container which is ideal for storing lithium ion batteries. It can be used
to store batteries safely and securely for both short and long periods. When being used for transportation, the
RETRON cushions inside the box also protect the batteries from shaking.
Use a suitable means of securing the RETRON BOX during transportation in order to prevent damage to
the box and the lithium ion battery inside!
If a lithium ion battery self-ignites (for instance due to a short circuit), the RETRON BOX reduces the risk of the re
spreading to the surrounding area. However, in the event of a re, it is inevitable that the RETRON BOX will heat up
considerably.
Ensure that a sucient distance is maintained between a loaded RETRON BOX and ammable objects in
the surrounding area. We recommend that the box is placed on a non-ammable mineral-based substrate.
6.3 WHAT TO DO IF BATTERIES SELF-IGNITE
zCall the re service immediately!
zNever open the RETRON BOX!
zInform the re service about the contents of the RETRON BOX.
In the event of a re, hot gases will be released through the ame-retardant grille in the main body of the RETRON
BOX. It is also possible that gas may escape from the lid seal.
WARNING
Risk of burns due to hot surfaces!
Do not touch the box while it is on re or after the re has stopped!
Do not open the box!
CAUTION
