Returning electronic components in warranty and goodwill cases
When returning electronic components it is absolutely essential to observe the procedure and safety
precautions listed. Electrostatic charge or discharge mean the original fault can be falsified or overlaid.
This can lead to distorted fault symptoms in the case of the fault analysis of the component concerned.

All models
General information on batteries
Do not store batteries over a longer period at a storage point with direct solar radiation.
l
Discharged or defective batteries can freeze, therefore store free from frost.
l
Avoid polarity reversal and short-circuits.
l
Do not place tool or other conducting objects on the battery (risk of short-circuit).
l
Before removal and installation of batteries all switchable current consumers should be switched off,
l
as well as the engine switched off so that inadvertent arcing is ruled out.
Always disconnect the negative terminal first and always connect the positive terminal first.
l
Only charge batteries with DC, 10 % of the capacity is recommended as charging current for slow
l
charging and 50 % of the capacity recommended for fast charging.
Only switch on the charger after connecting to the terminals and switch off before disconnecting.
l
We recommend greasing the batteries slightly with battery terminal grease.
l
If the battery is to remain in the parked vehicle for a longer time, the negative terminal should be
l
disconnected.
If possible batteries should be kept clean and dry.
l
Batteries should not be stored over a longer period without recharging.

Notes on lead-gel batteries (additional battery for special bodies)
Lead-gel batteries are free from gassing, acid does not run out of them and are completely
l
independent of position and maintenance free.
When fast charging ensure that the housing of the lead-gel battery does not heat up excessively
l
otherwise a pressure relief valve will be opened and the lead-gel battery will be defective.
Notes on lead acid batteries
Always store lead lead-acid batteries horizontally to prevent acid leaking out and do not tilt during
l
transportation.
When fast charging ensure that the housing of the lead-acid battery does not heat up excessively.
