What Are The Symptoms Related To A Bad Battery

The battery is considered dead when there isn’t enough charge to start the engine or run electrical components.

Normally, the first sign is dim lighting in the interior of the vehicle, and when you try to start it, the engine may crank slowly, or not at all. A very rapid clicking noise is normally heard if there is any charge left in the battery, but in many cases the vehicle will be completely unresponsive.

If the battery is losing charge while driving the vehicle, the battery warning light will illuminate, and the engine may stall.

Removing The Prius Battery

Before starting the work you will need to decide whether you want to keep power to the vehicle at all times. Failure to do so is not a major problem but you will lose such information as the radio presets and power window limits if you don’t maintain power. Neither is a big thing to correctinput the radio information again and run the windows up and down a few times.

If you want to avoid this small problem, you will need another battery and jumper cables or a battery charger. Instructions are in the section below, and once the power source is connected you can proceed. Do take notice of the caution given there.

You are ready to install the new 12-volt Prius battery.

Reasons To Avoid Prius Battery Repairs

Earlier, we discussed how some people try to prolong the replacement with a Prius battery repair. However, there are some reasons why you should avoid these practices.

  • Temporary: These hybrid battery repairs are only temporary. You arent going to dramatically extend the life of the battery. Even after the labor and cost of the repair, you will still need to have a replacement done anyway, thereby costing you more money in the long run.
  • Voids warranty: If your hybrid battery is still under warranty coverage, repairing it is going to void it. Plus, why would you want to avoid the replacement when the battery is covered for free during this time?
  • Dangerous: The hybrid battery is not like your traditional car battery. You dont want to mess with it if you arent qualified or serious damage could occur.

Instead of trying to find a shortcut around the repair, bite the bullet and get it replaced. Not only will you ensure the hybrid vehicle continues running as it should, but you also guarantee plenty more miles of travel from behind the wheel of your fuel-efficient vehicle. Budget accordingly so you are never unprepared for whats to come.

How Does A Toyota Prius Compare To Other Hybrids On The Market

Despite the Toyota Prius hybrid being one of the first widely marketed and popular hybrid vehicles, there are plenty of other hybrid options available on the market today, in a wide array of makes and models. So, how does the Toyota Prius stand up to its competitors? Firstly, you need to know that there are two types of hybrid vehicles, including full hybrids and plug-in ones.

The main difference between these two types of hybrids is the way the battery charges. A full hybrid charges from a huge battery pack that draws power from the gasoline engine and the brakes. The plug-in hybrids can be just that, plugged in.

The Toyota Prius battery is made up of 28 Panasonic nickel-metal hydride modules, each containing six 1.2-volt cells. Connected in a series, they will produce a total of 201.6 volts. This is compared to the Lexus RX 400h which can deliver 500 volts.

When To Replace A Car Battery

  • Your car doesnt start. A new battery has a specified capacity to provide power. This capacity is referred to as the cranking amps rating of the battery. As a battery ages, the actual amps that a battery can supply becomes lower than its original rating Once the cranking amps fall below a critical threshold, it will be difficult or impossible to start your car.
  • Battery or charging system warning light is illuminated. Should a battery or charging system warning light illuminate, a mechanic should perform a few basic tests to determine if a battery replacement is needed.
  • Electrical components dont work. Once a battery has started to fail, and the voltage produced by the battery drops, then vehicle electrical components can malfunction, such as the security system. If you are experiencing electrical malfunctions, its a smart idea to have the battery tested.

Why The Toyota Prius 12v Auxiliary Battery Costs So Much

Toyota Prius Starting Battery

If you have been a victim of 12v battery prices, I feel you. I have purchased many “special” batteries for my Prius’ and each time about choked at the cost.

Why on earth would Toyota make such an expensive battery for these cars if all they are going to do is die anyway? Well, here are a few things you need to know about that battery and why it is so darn expensive.

Why Your Prius 12v Battery Is DifferentMany do not know that the 12v battery in your Prius is different they only know it is expensive. The 12v battery in Prius is a different animal and for a good reason. Toyota wanted to have a battery that could handle the type of use that these batteries get.

AGM or Absorbed Glass Mat batteries are built very differently than a typical lead-acid battery. With AGM batteries, there is no “free” liquid electrolyte. The “mats” inside the cell hold all the electrolytes. This action makes the battery non-spillable and much safer. AGM batteries perform better than “flooded” batteries in applications where maintenance is difficult to implement. AGM also has minimal gassing when charging, making it a safer choice in many forms.

Also, the onboard charging system for Prius Generations 1, 2, 3 was designed for AGM, not lead-acid. That means when the 12v is undergoing charge, the onboard computer is looking for a specific internal resistance of an AGM battery. SO if you put in a flooded style, it will not charge that battery correctly, and it will fail.

Dont Test Right After Charging

More often than not, youll need to charge the battery before you can test it, but if you test it right after charging, a bad battery may seem like its OK. Also, the battery produces hydrogen gas while charging and a bad load tester clamp connection can cause a spark and explosion. Either let the battery rest for a few hours or test it 3 times, waiting around 5 minutes between each test. The first two tests will burn off any surface charge.

What Is Prius Battery Replacement

All batteries lose their effectiveness eventually. Replacing a Prius battery is relatively quick if done at a certified dealership on a scheduled appointment. The technicians will carefully remove the cargo interior mats and gain access to the battery. From there, the technician must properly disconnect, remove, and replace the old battery with a new one.

What Is The Specific Type Of Toyota Prius Battery

Most Toyota models, including Prius, use a 12-volts AGM battery. AGM stands for Absorbent Glass Mat, which is a specific type of battery that comes with thin and sponge-like features and glass mat separators. Aside from cars, it is also used to power key fob sensors, lock actuators, and security systems.

These remarkable elements allow the battery to smoothly absorb liquid electrolytes to deliver top-notch performance. On top of that, AGM batteries do not spill, making them much safer and last longer than lead-acid types.

In general, the common lifespan of a 12-volt gel is around 5 to 6 years, if thoroughly kept in a charged state when not in use. After this period, the batteries decrease their original capacity or years of float voltage, from 100% down to 80%. However, temperature plays a pivotal role in the health of the battery.

Batteries that are past their prime years should be working at average ambient temperature or else it would increase their deterioration state.

Why Spend 10 Times More On A Special Agm 12

Since Toyota started making its best-selling Toyota Prius Hybrid, for whatever reason if the battery went dead, Prius owners shelled out at least $200 or more to replace the trunk-mounted AGM 12-Volt.

Since the battery is close to the passenger area, Toyota used a sealed, valve-regulated, recombinant AGM battery that doesnt leak fluid or vent under normal operation.Maintenance free AGM batteries mean worry free operations.

Contrast that to traditional lead-acid batteries vent trace amounts of possibly dangerous and toxic hydrogen and hydrogen sulfide.
