The LinkRunner AT and LinkSprinter units both require AA batteries. Some batteries are prone to leakage in your device and can cause irreversible damage that is not covered under warranty or AllyCare. Battery corrosion is not a NetAlly manufacturing defect. The use by date stamped on the battery is not a guarantee that the battery will not leak until that date. The battery expiration date is the shelf-life date. Please contact the battery manufacturer for more information.
Important Note: If you will not be using your LinkSprinter for a length of time, 1-3 months for example, remove the batteries from your device.
