Batteries
Koltec has developed two new batteries with a longer life time.
Special for the Mushroom type fencer a 6Volt Alkaline
battery with 510Wh(100Ah) energie was developed.
Balanced for a perfect working Mushroom/ST.
This battery has a lower voltage than the old one.
This is neccessary to compensate the lower internal resistance of an alkaline battery. By doing this the Mushroom type fencer runs more smoothly and stabil, without damaging and burning the contactpoints.

The large 9 Volt Alkaline battery with 1500Wh (200Ah) energy is
the most powerfull battery in the market. Ideal for strong battery fencers which should last a full saison on a battery.
