OPEN THE SCREW CONNECTIONS ON THE BATTERY COVER.
IT’S THIS EASY.
How can I open the screw connections of a Banner battery?
The top label usually has to be removed first to open the battery plugs.
Why and how to open?
This is necessary before charging a battery to check the electrolyte level or to measure the acid density with an acid tester (hydrometer)
Please be sure to use an appropriately sized slotted screwdriver (slotted screwdriver) or the special “plug screwdriver” from Banner to open the cell plugs. The screwdriver should have a blade width of at least 14 mm (maximum 16 mm). If you use a screwdriver that is too small, the plug or the “cross slot” will be damaged and disassembly will be more difficult or no longer non-destructively possible.
The plugs have a tight fit due to the special sealing ring. This tight fit is necessary to ensure the user maximum protection from electrostatic discharge (ESD*).
When handling lead-acid batteries, please be sure to wear safety goggles!
PLEASE NOTE:
Before charging, check the electrolyte level and, if necessary, fill with desalinated or distilled water to the max. acid residue mark or 15 mm above the upper edge of the plate.
The battery screw connections must not be kept open during charging and it is best to close them again.
Running Bull AGM/BackUp: AGM batteries must not be opened. It is not possible or necessary to measure the acid density or top up with distilled water.
* ESD = ElectroStatic Discharge. Electrostatic discharges are voltage breakdowns caused by large potential differences. These discharges (may be visible as sparks) cause a short, high electric current and can lead to the ignition of flammable substances. Using special plugs, we have succeeded in minimising the risk of a breakdown (in the event of an electrostatic discharge).
