STC Fully-automatic standard charger Fully-automatic standard charger The STC charger is a fully-automatic standard charger designed for charging of open traction lead-acid batteries. The charging is performed according to Wa charging characteristics where the charging current decreases as the battery voltage increases. When the battery is connected and the charger is switched on, the automatism assumes control so that the battery can achieve the correct charging in relation to its condition and discharging depth.

Choice of Charger
The STC charger’s Wa charging curve is the most simple charging characteristic in the charging range of GNB Industrial Power.
The charger provides the battery with “fuel” which again supplies energy to the truck, just as petrol does to the car’s petrol engine – and who would dream of filling 92 octane petrol into a 98 octane engine?
For normal operation when charging time is not so important and the battery is not a very expensive battery, this type of charger is still the most economic choice. But when charging times and battery sizes are of more vital importance, you should choose the intelligent constant current charger as it charges the battery more gently and in less than 6 hours.
Incorrect battery charging will quite simply ruin the battery gradually or perhaps very quickly. Therefore, it is important to realise what performance you require from your “charger/battery package” – both now and in future. >D o you require heavy duty or normal
The charger is protected against too high temperatures and will shut off temporarily if the transformer becomes too warm. During charging the charging process is indicated with 3 LEDs – 2 yellow ones and 1 green one.
operation? >D o you have long or short charging

do you work 24 hours a day?
The 2 yellow LEDs indicate that main charging and after charging respectively is in progress. The green LED indicates that the battery is fully charged and that maintenance charging has been commenced.
These questions should be clarified before buying your charger.
Charging Process

MC – main charging Descending current up to 2.42 V/c – max. 10 hours PC – after charging Approx. 60% of the main charging time – min. 3/4 hours MC – maintenance charging When the cell voltage falls to 2.17 V/c, pulse charging is performed for approx. 1.3 minutes. The interval between each pulse is at least 20 minutes. If the total charging time of 16 hours is exceeded, the charger automatically switches to after charging.
