Having read the manual, I am of the same view as SD1too that this is a simple voltmeter. This being the case, the question to ask yourselves is whether it is really giving you any useful information about the battery's condition.
Personally, I would suggest that anyone who has sufficient knowledge to want to test a battery could achieve better understanding of their battery's state of charge with a £5 voltmeter and knowledge gained from watching a youtube video on how to test a car battery and charging system. For myself, an old fashioned load tester of the type here would be a far more useful tool. https://www.ffx.co.uk/product/Get/Si...Tester-6V--12V Alternatively, if one wishes for something a bit more sophisticated, one of these would be a useful tool. https://www.gendan.co.uk/product_FXBT715.html Best of all, just keep your battery fully charged with a maintenance charger such as a CTEK and listen to how vigorously the engine cranks after the main beams have been left on for around 30 minutes with the engine off. As a side point, I think people often confuse between the state of the battery and the state of the charge held by the battery at any one point in time. |
