You can either use a battery charger, drive or idle for at least 20 minutes to charge the battery, or receive a jump start from another vehicle.
- You will need jumper cables and a car whose battery is not dead in order to jump-start your vehicle.
- Find a driver whose car’s battery is still good. Check to see if they have jumper cables. Find someone with jumper cables if they don’t.
- Place a working vehicle with a booster battery next to the vehicle with a dead battery, being careful to keep the two vehicles apart.
- Make that the booster battery is 12-volts and has the grounding wire attached to the negative terminal.
- Unnecessary electrical loads should be turned off.
- Remove the service cover from the engine compartment’s front passenger seat side by opening the engine hood.
- The make and model of your car determines how easily you can access your battery. Some might even be hidden behind the seats or in the boot.
- Take off the fuse box lid. Open the negative terminal cap near the car body and the positive terminal cap within the engine room fuse box.
- Connect the positive end of the discharged battery to the red, positive clamped end of a jumper cable.
- Connect the other end (red positive clamp) to the booster battery’s positive terminal.
- The other jumper cable’s (black, negative clamp) other end should be connected to the negative terminal of the booster battery, and the other end should be connected to a stationary, solid metallic object far from the battery.
- Start the engine of the working vehicle and let it run for a few seconds to start charging the dead vehicle’s battery with the jumper cables.
- When the dead car starts, unplug the jumper wires in the opposite order (first the black, negative clamps, then the red, positive clamps), being careful to avoid touching the clamps.
- To build up the charge, take a little drive or leave it idle for at least 20 minutes.
To charge your battery, adhere to the simple directions below:
- Make sure you turn off the battery charger.
- Connect the charger’s positive and negative cables to the appropriate ends of the battery.
- Turn on the charger when it is charging at its slowest rate, and then set the timer. It should take 6 to 12 hours to fully charge, depending on the battery voltage and cold cranking amps (CCA).
- After finishing, switch off the main battery charger.
- Negative and positive clamps should be disconnected from the corresponding battery terminals in that order.

How is a Kia Optima charged?
Directly insert the trickle charger into the power outlet. Your Optima Plug-In Hybrid is best charged using a Level 2 or “standard 240-volt charger.”
How is a dead Optima battery recharged?
- a strong battery, ideally one that is over 12.2 volts. (It may be an inundated or AGM battery.)
- Deeply drained and presumably dead AGM battery
- voltage gauge
- a timer or watch
Start by connecting the healthy battery and the AGM battery that has been deeply discharged in parallel, positive to positive and negative to negative. Next, connect the healthy battery to the charger and turn it on. The battery charger “observe the voltage of the healthy battery (connected in parallel), then begin to supply a charge. Check to see whether the AGM battery is warm to the touch or heated after the batteries have been charging for an hour. Although batteries naturally get warm during charging, excessive heat could be a sign that the battery is actually broken.
Important: If the battery feels warm to the touch or if you hear the battery clicking, stop charging right away “Safety valves can be heard hissing as they operate.
Check the AGM battery frequently with your voltage meter to verify whether it has charged to 10.5 volts or more. With a 10-amp charger, this typically takes around two hours. Remove the good battery from the charger as soon as it hits the 10.5-volt mark and unplug the charger from the power outlet. Now, only attach the AGM battery that has been deeply discharged to the charger. Start the charger and keep going until the AGM battery is fully charged or the automatic charger has finished charging the battery.
How can I charge the battery of my parked car?
A specific device that stays on your battery for a long time is called a trickle charger. It is intended to gradually feed electricity into your battery to charge it.
This charger features a positive and a negative wire that will plug into a power outlet. All you have to do is connect it to your automobile while not in use.
Take a Lap (or Ten)
By doing a few laps, you can truly recharge your battery. According to auto specialists, you should travel at a speed of 30 mph for about 30 minutes. The best technique to get your alternator churning and cranking electricity back into your battery appears to be this.
As you’re doing this, I’d also advise shutting off the AC and the radio. This will improve the charge by reducing the amount of electricity lost.

How is a dead hybrid battery recharged?
- The hybrid battery will be in the fuse box, which may be found by lifting the hood.
- Attach the red jumper cable to the battery’s positive (+) terminal. Connect the same cable to the positive terminal (+) of a second car by running it there.
- Connect one end of the black jumper cable to the unpainted metal component on the dead automobile, and the other end to the negative (-) terminal on the battery of the functional vehicle.
- Start the second car’s engine, and then let it run for a while.
- Start the Prius and watch for the Ready notification to appear on the dash.
- Once the connections are disconnected, you should be set to go.
However, if you drive the car for roughly 20 minutes, the hybrid battery should recharge on its own. Therefore, if your battery is continually depleting to the point that your Prius won’t start, it’s usually a symptom of bigger problems or that the battery needs to be replaced entirely.
A Prius battery replacement is not inexpensive. Parts and labor should cost between $2,500 and $4,500. When this occurs, many Prius owners even consider purchasing a new car.

Do OPTIMA batteries require a unique charger?
Can I charge my OPTIMA battery with a standard or factory charger? In almost every situation, the response is without a doubt! It’s a frequent fallacy that because lead-acid batteries are their intended purpose, conventional chargers or the OE battery chargers that arrive with new cars cannot charge OPTIMA batteries.
OPTIMA batteries: are they rechargeable?
OPTIMA batteries may undoubtedly be recharged after use, just like any other automotive or marine battery. In actuality, it occurs frequently. The majority of automobiles feature built-in charging mechanisms that recharge OPTIMA batteries while the engine is operating, most frequently in the form of an alternator.
What symptoms indicate a faulty Optima battery?
Even if your Optima’s voltage is fine, it could still struggle under load. You can load test it using a multimeter or by visiting an auto parts store (they all have battery testers these days).
By connecting it to a car and monitoring the voltage while the starter is running, we load test it. What you should do is:
Like before, you’ll set your multimeter to 20VDC or another setting that will get you close to the 12 volt DC range.
Touch the black probe to the Optima’s negative terminal and the red probe to its positive terminal.
Have a helper then attempt to start your 4×4. (Tip: If we’re driving alone, we’ll set the multimeter on the windshield and reach the battery with long alligator clips.)
Instead of watching the multimeter while you’re running, watch it as the starter motor turns!
We use that tremendous load to test the battery’s performance when the starter motor starts the engine. When the alternator is turned on, it will begin to increase the voltage, but we aren’t concerned in alternator voltage because that only indicates how well your Optima is charging.
Your battery is dead if the voltage doesn’t stay between 9.5 and 10.5 volts for 30 seconds. Typically, one of these two things occurs:
- too much sulfation
- a vacant cell
Heat is the reason an open cell appears to be fine in your Optima’s no-load testing:
Things that should touch can stop touching when a battery is heated up inside, causing it to expand. Similar internal breaks or cracks can occur in terminal contacts. When they are cold, they might touch and flow current, but as they warm up, they split apart from one another.
