Delorme InReach SE Battery Life
I am seriously considering a purchase of the Delorme InReach SE (http://www.inreachdelorme.com/product-info/). I am looking for a two-way communication device that does not require pairing with a smart phone (since I do not own one). I used a Spot 3 last year and found it acceptable but I did not like the fact that I had to wait a considerable period of time to ensure that OK messages were delivered and had no confirmation of delivery. My hope for the InReach is that I can get confirmation more quickly and also receive messages in cases of emergency.
Other than the steep cost of the device and the service plan, one factor is really bothering me and preventing me from making the purchase at the moment. The issue is that the InReach uses an internal battery and must be recharged. I find this to be a real limitation on a device intended for use in the wilderness where replaceable batteries seem preferable.
I'm looking for feedback from anyone who owns this device in terms of battery life I can expect. I do not care about constant tracking and would intend to leave the device off except when sending/receiving messages which I would do maybe twice per day. With this limited usage pattern, could I expect a couple of weeks of battery life?
