We guarantee a certain battery life for our Active Transponders. This warranty is limited to transponders not using Tracking Mode, and we also need to take into account further considerations. 

As the transponders are sealed and the battery is inside the transponders, there is no way of disconnecting the battery to reduce its consumption. The transponder has a constant drain on the battery to stay "alive". When being activated, the battery consumption is highest, therefore, if there is any electromagnetic interference, the standby consumption will increase. 

The Deep Sleep Mode is the only option to reduce battery consumption as much as possible when not being used and extend the shelf-life as much as possible. Learn more about the transponder battery and its consumption in this video.

Furthermore, to grant the above warranty the following preconditions must be met:
a) Transponders are stored in proper conditions. This means there is no electromagnetic interference which may drain the battery. Please note that any electrical device has the potential to activate the transponder and draw the transponder's battery unnecessarily. If you want to check your storage conditions, we recommend checking the area with our 125kHz Detector, which is available in our Online Shop.
b) Transponders are not constantly held within the activation field of a loop, neither for testing nor after collecting them at the end of an event. It is of course not a problem to detect transponders for testing, but letting them sit in the detection area for several minutes, or even hours, will drastically reduce the battery life.

What happens if your transponder's batteries are empty before the end of the warranty? If the above preconditions are met, we will offer you two options:
a) we will provide rental transponders until the end of the warranty period.
b) we will offer you a "trade-in" discount accounting for the loss of warranty time, based on periods of six months. For every six months the battery life falls short of the warranty, we will give you a proportional discount based on your initial purchase price to replace your "empty transponders" with new ones.
