You can test a battery if you go under the hood and connect up the right meter to measure the battery integrity but why can’t a modern car employ the technology easily? (Or maybe it does and I need a new car)
In: Engineering
There’s a battery light that pops up when battery voltage is low on some cars. Diagnosing lead-acid battery health is not as simple as measuring voltage, it can be near full voltage and go down super low when you actually try and draw power. You’re required to change batteries often enough that it shouldn’t be a problem, but many people only change them when they die leaving them in a field.
