Assuming you mean the 12-volt battery: Yes. The 12-volt battery in a Prius can be charged manually with a standard household outlet and a trickle charger.
To do so, first, disconnect the negative terminal of the battery. Next, connect the trickle charger’s positive lead to the battery’s positive terminal. Finally, plug the charger into a household outlet and turn it on.
- Park your Prius in a well-ventilated area and turn off the engine;
- Lift the hood and locate the black, rectangular battery charger port on the driver’s side of the engine compartment near the bottom of the windshield;
- Open the cover to the battery charger port and insert the charging cable’s red clip into the “+” terminal and the black clip into the “-“ terminal;
- Plug in the other end of the charging cable to a power outlet and wait for the LED light on the charger to turn green, indicating that it is working correctly;
- Monitor progress by checking voltage levels with a voltmeter until the desired level is reached; remove cables from both battery terminals when done charging by reversing the order of the attachment process described in Step 3.
How Do You Charge a Dead Prius Battery?
Assuming you have a Prius with an HV (High Voltage) battery: If your 12-volt auxiliary battery is dead, your HV battery is probably also dead and will need to be charged. To charge the HV battery, you’ll need to take it to a Toyota dealership or an independent shop with the proper equipment.
- The process begins by connecting the charging station’s negative lead to the car’s chassis.
- The positive lead from the charger is then connected to the HV service port under the hood, which looks like a standard automotive electrical connector. Once these connections are made, the charger will start delivering power to the battery.
The process can take up to eight hours, during which time you’ll need to leave your car at the shop. Once the charging is complete, the technician will disconnect the leads and test drive your car to ensure everything is working correctly before sending you on your way.
Can You Manually Charge a Hybrid Battery?
When it comes to hybrid batteries, there are a lot of misconceptions out there. One common question we get is whether or not you can manually charge a hybrid battery. The answer is yes, you can manually charge a hybrid battery, but it’s not as simple as charging a traditional car battery. We have a detailed article on hybrid battery charging. Click here to read.
Here’s what you need to know about charging a hybrid battery:
| Number one | You can’t just plug in and start charging. Unlike traditional car batteries, which you can simply hook up to a charger and start charging, hybrid batteries need to be charged using a special process called “conditioning.” This involves slowly charging and discharging the battery over time to help extend its life. |
| Number two | It takes longer to charge. Because of the conditioning process, it takes significantly longer to charge a hybrid battery than it does to charge a traditional car battery. In most cases, it will take several hours to charge a hybrid battery fully. |
| Number three | You may not need to do it often. Many assume they’ll need to recharge their hybrid batteries regularly, but this isn’t necessarily the case. With proper care and maintenance, your hybrid battery should last many years without needing to be recharged. |
| Number four | While rare, there is always the potential for damage when working with electrical components like batteries. If you’re uncomfortable working with electricity, we recommend leaving this task to the professionals. |

Trickle Charge Prius 12V Battery
A trickle charge is a low, continuous charge used to maintain a lead-acid battery’s state of charge. It is typically used on batteries, not in use for long periods, such as those in storage.
A lead-acid battery will self-discharge at a rate of about 3-5% per month, so a trickle charger is used to replenish the lost charge and keep the battery ready for use.
The 12V battery in a Toyota Prius needs to be trickle charged if the car is stored for more than 2 months. To do this, you’ll need to connect the negative terminal of the 12V battery to the ground and the positive terminal to a 10mA constant current source. The easiest way is with a commercial trickle charger designed for automotive batteries.
If you don’t have access to a commercial charger, you can make your own by connecting a resistor in series with a 10W (or greater) lamp between the battery’s positive terminal and your 12V power source. This will provide approximately 10mA of charging current. Be sure to disconnect this setup when you start using your Prius again – otherwise, you’ll discharge your power source.
How to Charge Toyota Prius Hybrid Battery?
When it comes to charging a Toyota Prius hybrid battery, there are a few things you need to keep in mind:

- Finally, once the battery is fully charged, reconnect the negative cable before driving away!
How to Charge 2007 Prius Battery?
As the owner of a 2007 Prius, you may be wondering how to charge the battery.
The good news is that there are a few different ways to do this, and we’ll go over them here:
First, it’s essential to know that the 2007 Prius uses a nickel-metal hydride (NiMH) battery. This type of battery differs from the lead-acid batteries in most cars, requiring special care.
| Option one | One way to charge your 2007 Prius battery is by using a 120-volt AC charger. This charger plugs into a standard household outlet and takes about six hours to charge the battery fully. |
| Option two | Another option is to use a 240-volt AC charger, which will charge the battery half the time as the 120-volt charger. However, this charger requires special wiring in your home and can only be used if you have access to an industrial outlet. |
There are also DC chargers available if you need to charge your 2007 Prius battery while on the go. These chargers plug into any standard cigarette lighter socket and will charge your battery in about three hours. Click here to find more information about Prius battery charging.
How to Keep a Prius Battery Charged?
If you own a Toyota Prius, chances are you want to do everything you can to keep it running smoothly. That includes making sure the battery is always charged.
Here are some tips on how to keep your Prius battery charged:
Check the Battery Regularly
The first step is to check the battery regularly. You can open the hood and look at the battery itself. If it looks low, then it’s probably time to give it a charge.
Charge It Up Every Few Months
Even if the battery looks fine, giving it a full charge every few months is still a good idea. This will help ensure that it stays in good shape and doesn’t run out of juice when you need it most.
Use a Charger Designed for Priuses
When you charge your Prius battery, use a charger specifically designed for Priuses. These chargers will work best and won’t damage your battery as some generic chargers can.
Keep an Eye on Your Warning Lights
Monitoring your vehicle’s warning lights is important for all drivers but becomes increasingly critical as cars become more complex each year.
One light in particular that Prius owners should be aware of is the “red triangle with an exclamation point,” which indicates a problem with the hybrid system – usually related to either the gas engine or the electric motor not working correctly, or more commonly, an issue with the 12-volt auxiliary battery located under the front passenger seat.
If this light comes on while driving, safely pull over as soon as possible and call for roadside assistance.
Check Fluid Levels
In addition to keeping an eye on warning lights, also be sure to check fluid levels (engine oil, brake fluid) and tire pressure monthly – simple maintenance tasks that can save big headaches (and money) down the road.
Drive Smarter
Perhaps obvious but often overlooked – driving smarter can help improve fuel economy, directly impacting how often you need to recharge your hybrid car’s batteries.
Avoiding short trips where frequent starting and stopping occurs is ideal since this puts unnecessary stress on the gas engine and electric motor, which reduces fuel efficiency. When driving long distances at highway speeds, however, fuel economy plummets, so recharging en route may be necessary to prevent being stranded without power.
How Long to Charge Prius 12V Battery?
Assuming you are talking about the 12-volt battery in a Toyota Prius and not the high-voltage battery, there are a couple of things to consider. The 12-volt battery is used to start the car and provide power to accessories when the engine is off. It is not used to power the car while driving.
- The 12-volt battery will need to be charged if it discharges below 10 volts or has been more than six months since it was last charged. You can charge the 12-volt battery with a standard automotive battery charger or jumper cables connected to another running vehicle. To charge the 12-volt battery, connect the positive (red) lead from the charger or jumper cables to the positive terminal on the battery.
- Then connect the negative (black) lead from the charger or jumper cables to a metal ground on the vehicle (not directly on the battery’s negative terminal).
- Finally, plug in the charger or start up the other vehicle and let it run for a few minutes before revving up its engine too much – this could overcharge the system and cause the fuse to pop.
