Has anyone fitted a Battery Health Monitor ?
I don’t drive my ND evey day … Motorcycle wins in the sun 
So wanted to know how my car battery was doing … battery drain can be a problem with an alarm and a tracker . This monitor helps plus it’s cheap as chips

Go for it and let us know how it goes.
Will be interested to hear how you get on.
Personally, if there is mains power available where the car lives, I’d put the money towards a C-Tek or similar trickle charger, which means that the battery will always be fully charged when you need it.
No mains … If only .
I’m sure it’s frowned upon to wire it to a street light 
I’ve got exactly that battery monitor on my NC. It’s been on for about 9 months now and is an excellent bit of kit for a car which sits idle for long periods.
If I had to be critical, the bluetooth only has a range of a few feet, so you have to stand next to the car to get a reading; it obviously works when the phone and app are in the car when driving!
I use it in conjunction with a solar panel to keep the battery charged - there’s a previous thread about that elsewhere.
I have a solar panel on the “parcel shelf” so during the day if it’s parked up it can and does trickle charge the battery … My ND has never had a problem starting but my MK2.5 I had didn’t like being left for very long
