1.1 Using the documentation
Before commissioning, connecting and using Bosch
products, it is essential to go through the operating in‐
structions – and the safety instructions, in particular –
with great care. By doing so, you can eliminate any un‐
certainties in handling Bosch products and associated
safety risks upfront, which is in the interest of your own
safety and will help avoid damage to the products.
Should a Bosch product be passed on to another per‐
son, the operating instructions with information on its
intended use must be handed over as well.

2.1 Safety instructions
Voltage must be supplied to BAT 6120 via a grounded
mains voltage system.
The power supply cable and battery cable B+/B– must
be in perfect condition.
Only use the battery cable B+/B– supplied by Bosch.
Do not extend or shorten the battery cable B+/B–.
When using an extension cable, make sure that the to‐
tal current of all devices connected to this extension
cable does not exceed the permissible current for the
extension cable and the upstream fuse in the fuse
box.
Only charge batteries in well ventilated areas.
Avoid naked ames and spark formation when charg‐
ing batteries.
Do not attempt to charge non-rechargeable batteries.
Do not charge lithium iron phosphate batteries (LFP =
LiFePO4) without the battery management system
(BMS).
Switch off all electrical equipment in the vehicle
whilst charging (also applies to charging of exhausted
batteries).
Do not short-circuit battery terminals.
---
Battery hazard
Risk of chemical burns – Electrolyte leaking from bat‐
teries and accumulators may cause eye and skin burns.
Make sure that any leaking liquid (electrolyte) does
not come into contact with skin or eyes.
If electrolyte contacts the relevant areas, immediately
rinse with water and then consult a medical professio‐
nal.
Do not short-circuit batteries and accumulators.
---
Risk of re, explosion – Batteries and accumulators
can cause burns and injury if overcharged (gassed) or
short-circuited.
No open ames or sources of sparks.
Do not smoke.
Ensure that there is su󹓜cient ventilation and extrac‐
tion in enclosed rooms.

3.3 Functional description
The powerful battery charger BAT 6120 can be used to
charge the following batteries:
•12 V lead-acid batteries, e.g. batteries with xed
electrolyte (gel batteries or eece/AGM batteries).
•12 V lithium iron phosphate (LFP = LiFePO4) batter‐
ies with battery management system (BMS).
The batteries can be charged either in the vehicle while
installed or when removed. The BAT 6120 can also be
used to supply voltage to the vehicle electrical system
when replacing batteries or programming control units.
Other applications include supplying power to the vehi‐
cle electrical system when troubleshooting the vehicle
