ANCEL Battery Monitor 4+

I had no troubled installing the battery analyzer on my new car battery. I live in Arizona and car batteries have a predictable two year life because of the heat. My car is a Tesla and if the 12V goes without warning you lose access to the vehicle along with almost every function except the motor which is a completely separate system. I also just installed a new Li Ion 12V battery which is guaranteed to last 48 months and reviews well exceed that. So the Issue for me is uncharted territory. The voltage part of the analyzer is all I need so the instructions are not critical but printed instructions will help anyone who needs more functions. They are really almost indecipherable to an English speaker. They desperately need to be written by a native or fluent English speaker. Useless otherwise.

ANCEL Battery Monitor is a great app to monitor your battery’s health. You need a physical hardware in conjunction with blue tooth. It allows you to see crank voltage and voltage over time at idle and charging. I would give this a 5-star if it allows e Perot of the data to PDF format especially trip data. I do hope the developers add this feature as future updates.

Install the unit on my Tesla OEM battery, and immediately I could tell that this was a joke of a product. The fonts did not allow the messages to be displayed, the graphs were not accurate or legible and cannot update firmware using the app.

Contacted support and ask they did was want to ask me more questions rather than offer simple answer to, is there newer firmware. The questions appear to be from ChatBot AI and the more I asked for support, the more they asked ridiculous questions that had nothing to do with the device.

I would not recommend this at all since my confidence in the readings are very suspect.
