(3-Pack) Exell Weather Station Batteries - Compatible with Oregon Scientific STR918/STR928/STR938/STR968 - Replacement for 25AAH3BMX-2 - Perfect for Home Weather Monitoring, Outdoor Thermometers & Scientific Instruments

These batteries claim they are for Oregon Scientific weather stations but are a significant danger to your sensors. The batteries come from the factory with the plug wired backwards which will burn out sensors immediately. If you purchase these carefully compare the plug to the plug in the unit. This is not a new problem - I bought the same ones several years ago and they were also wired backwards. If you have small tools and skill it is possible to remove the connectors from the plugs and reverse them.
