On the subject of car gadget gizmos I’ve been using a CTEK CTX Battery Sense Car Battery monitor for just under 1 Year now.
Available from Amazon here
this little gizmo attaches to the car battery and sends voltage and temperature information on the battery health via Bluetooth to a smart phone. The temperature is of the engine bay, not the battery. It just so happens on the 1 September 2018, I changed the battery in my car to a new Silver Bosch support mega battery with a 5 year guarantee. So I was interested in it’s health.
CTEK CTX Battery Sense
It stores all the graphs on your smartphone, this was the first time the battery was connected from new, so only had 60% charge, and gradually charged to 100% over a few days, when driving the car.
