Can I use rechargeable batteries?

Yes, in theory. However even in good conditions rechargeable batteries will only last half as long as standard alkaline cells. In particular the Gateway struggles if the rechargeable batteries are not in good condition. A better solution is to use an external battery pack which can be constantly charged by a solar panel. This provides for continuous power supply. We can supply a spec for the battery pack and solar panel and also supply the special cable to connect external power to the Gateway.  Contact  sales@arnia.co.uk.to find out more.

We strongly recommend using alkaline D-cells. Batteries should always be changed in a dry environment or conditions to avoid any moisture getting in to the units. Ensure the lids are tightly screwed on after changing batteries to avoid any moisture ingress.

We have a YouTube video that shows you how to change your batteries; Battery Change Instructions
