What car battery voltage is too low?
I’m driving my fairly ancient 2005 Pontiac Sunfire to Maine for a holiday this summer. I want to make sure my battery doesn’t give out during my road trip. What’s considered too low for car battery voltage?

Maine
is a beautiful place, and the summer is a perfect time to visit! But, as nice as it is, the last thing you want is to be stranded with a Pontiac Sunfire
that won’t start. Generally, your car battery voltage is too low if it is reading at 12.4 volts or under.Your 12-volt battery should read at around 12.65 or higher on your voltmeter if it’s healthy and fully charged. If your battery drops to 12.5 volts, consider recharging it back to a full charge.
Between 12.2 and 12.45, your battery is operating at a 40% to 75% charge, and is on its way out. If your engine is
starting slowly
, your car lights are dim, or you hear a clicking sound when you turn the ignition, get your battery replaced before it fails. If your voltmeter reads 11.9 or under, your battery is considered dead and needs replacing.
