- In order to charge a dead car battery, a set of jumper cables and a functional car with a charged battery is required. You will then have the ability to connect the batteries to one another using the jumper cables, and re-charge the dead battery by transferring energy from the functional battery.llow at least 5 minutes to pass after starting the engine of the car with the charged battery. This will allow the dead battery to build up a charge of its own, although it would take longer to fully charge the battery. 8.

- The voltage is allowed to roam within a confined window while the charge current is set and will only moderate during saturation charge. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.he higher the number, the more capacity. A 65Ah battery can deliver 65 amps during 1 hour; or 1 amp during 65 hours, or 6.5 amps during 10 hours, and so on. The 100Ah has more capacity, so it will take longer to completely charge it, but it will last longer while it delivers power. It is like a gas tank in your car.

Your alternator doesn't charge your battery the way you think it does. Sure there might be some surplus power produced at speed, but to fully charge a nearly dead 12V battery would take a 2000 mile drive at 80mph or more with everything electrical turned off. A quick 10 minutes down the motorway isn't doing anything for you.

RPM and duration to recharge a battery? I bought mine for about $20 US and it will easily charge a nearly dead battery up to an acceptable level in about an hour (going from memory). If you do the math, the car is a terribly inefficient battery charging system.asically, at idle you can probably get 80 amps out of your alternator. You can charge a flat battery to 80 percent full in about 2 hours, so long as you alternator can manage produce around 14 volts at the battery terminals this whole time. share | improve this answer.

How to Pick the Right Battery Charger Step 2: Determining Battery Size. We don’t mean physical size, but how many amp hours your battery stores. For example, a typical full-size auto battery is about 50 amp hours, so you would choose a 10 amp charger that would take about 6 hours to recharge it if the battery were completely dead. Another instance would be a marine deep cycle battery rated at 100 amp hours.

- Keep in mind that most of the time, the battery will not be empty when you plug in, thus reducing charging time. To recharge a completely empty car battery from an ordinary 120-volt socket, the Chevy Volt plug-in hybrid would need 10 hours and the Nissan Leaf EV would need 20 hours. Using a faster 240-volt outlet and a charging station, the Volt recharges in about 4 hours and the Leaf in 8 hours. See our Accessory Tracker page for comparisoins of charging stations.
