Learn MoreA lead acid battery. It involves using a sensor that measures changes in the weight of the active chemicals present in the battery as it discharges. As the charge stored in the battery is used up, the concentration of sulfuric acid (an active electrolyte in the battery) decreases, which proportionately reduces the specific gravity of the solution.
Learn More$begingroup$ You could always do the load testing you mentioned in your question by creating your own custom battery tester - find out what kind of current draw your scooter has, then check eBay for some high wattage resistors that would give a similar drain, then hook them up across each battery and measure voltage over time. I see a …
