充电的时候需要把电池卸下来吗？
Follow the instructions for your particular charger. Basic instructions for most chargers include:
Make sure the charger is off.
Hook-up the positive cable on the charger to the positive terminal on the battery.
Hook up the negative cable on the charger to the negative terminal on the battery.
Set the charger to the slowest charge rate.
Turn on the charger and set the timer.
When removing the charger, turn it off first, then remove the positive then negative cable.
How Long Should You Charge a Car Battery?
If the battery voltage is below 11.85 and your charger is putting out a 5-amp charge rate, it will take about 12 hours to fully charge a battery with 400 to 500 cold-cranking amps. The same battery will take about 6 hours to fully charge if the charge rate is 10 amps. The lower the open-circuit voltage in the battery and the more cold-cranking amps, the longer it will take to charge the battery.
If a cell is bad, the battery won’t hold a charge. In this case, bring your battery or your vehicle with your battery to a local Meineke Car Care Center and we will change your vehicle’s battery.
If you can’t start your car, read our step-by-step instructions with pictures on how to jump-start a car battery, it may be helpful! |
