is responsible for any charges related to removal and reinstallation of radio devices as well as all freight charges associated with shipment of defective AND receipt of replacement radio devices. The replacement radio devices will only be warranted for the remaining period of the original radio device’s warranty period. Battery Comparison The Neptune R900radio reader The Neptune R900 is comprised of one D sized lithium battery, with a capacitor. The capacitor evens the draw on the battery, which extends the life of the battery. The Neptune R900 radio device with a constantly transmitting reading of 100 milliwatts of output power, every fourteen seconds, is rated for 20 years. The battery for the Neptune R900 is field replaceable, thus when the battery fails, City staff can replace just the battery, not the entire radio reading device, at a substantially lower cost. The Itron 60 Watt radio reader The Itron 60 Watt battery is comprised of two A cell lithium batteries. The previous generation of Itron’s 50 Watt radio device also had two A cell lithium batteries. Based on literature they supplied to the City 4 years ago by a vendor selling the Itron system, the 50 Watt radio device had a transmitting reading of one milliwatt of output power which was broadcasted every three seconds and an estimated battery life of ten years. Now the newest Itron 60 Watt radio reader has a transmitted reading of ten milliwatts of output power broadcasted every seven seconds and has an estimated battery life of twenty years. Based on this data, Staff finds this claim somewhat suspect. The battery for the Itron 60 Watt radio device is not field replaceable. Therefore, when the battery fails, and it will fail, City staff has to replace the entire radio reading device.
