- 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.

- The more discharged that a battery is, then the longer it will take to recharge it. Usually it takes several hours to effectively recharge a battery. If a battery is very discharged then it can take up to 12 hours or more to recharge it.While recharging a battery, if the battery becomes hot when you touch it then stop charging it. Slow charge: It is best to slow charge the battery.Slow charging rates vary depending on the battery's type and capacity.ast charge: Repeated fast charges on a battery may overcharge a battery and reduce service life. Step 1: Determine how long to recharge a battery by calculating how much capacity your battery has. For example, an Interstate battery with the part number MT-34 has 120 minutes reserve capacity.

How Long Does it Take To Charge an Electric Car? It depends on the type of batteries in the car and it depends on the type of outlet you're using to charge the thing up. Let's take a few real-world examples: - The Nissan LEAF uses lithium-ion batteries, just like your laptop and your cell phone, but it uses a lot more of them.It can charge overnight (8 hours) at a 220/240-volt Nissan charging dock that's installed in your garage.It can also charge at a 110/120-volt outlet, the kind you plug your laptop and cell phone into, but it'll take far, far longer.t can charge overnight (8 hours) at a 220/240-volt Nissan charging dock that's installed in your garage.

- The engine and charging system will work much better under load, while driving. Just idling the car for 20 minutes will not provide as good a charge as actually driving the car for 20 minutes. It will take about 20 minutes of driving to charge your battery. That is why short trips wear batteries out, they never get back up to full charge and the drain from starting the car doesn't get replaced.

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.

What are the causes for a car battery to totally discharge? If so, the alternator is good, and is pumping current into the battery using higher voltage. Let the car jump 5 minutes to charge the battery (the battery will reach full voltage in a few minutes if it is good, completely recharging it is another thing), and try to start it again. If it still won't start, the battery probably needs replacing, because it evidently won't hold a charge any more.
