They wont let you see the vehicle that it came out of and they will not give you a written guarantee that the battery will work (all electronics sales are final, look for it, its normally a sign on the wall behind the counter). Make sure the car isn't in "Ready" or "Accessory" modedon't press the brake to power into "Ready" mode. After more data logging and testing the overall health of my battery is around the 25% mark. The analog ammeter shows charge current going to the battery. 3) Turn the "Vset" knob counterclockwise to the stop. If it increases rapidly when charging, the battery may have a fault which results in an internal resistance much larger than the usual 0.55 ohms, which usually would give at most a 1.5 volt change when charging begins. When the ICE is running, the battery is charging. Any other code that starts with PA0 is most likely pointing to a bad battery. 
It is sealed unit that contains 6 (they are numbered) battery cells connected in series. "Insurance is only $8 a month?!" To place an order for the charger, first contact us at 505-466-3877 or the email address below. Do you need a license? It is now five 1.2V cells resulting in a 6 Volt module. Now lets take a look at a recording taken on the same car, with a brand new battery. Put it in reverse. Other indications include the hybrid system trouble warning (top left on multi-function display, red box w/ a car w/ an exclamation point through it), several yellow lights including check engine lights, VSC, ABS, ect. Thats a 3.5 volt difference. I am far from a battery expert, but of the three differences separation between Min Block V/ Max Block V, time to discharge, and separation between fully charged voltage and fully discharged voltage I feel that the separation between the Min Block Voltage and the Max Block Voltage will be the most reliable indicator of overall battery pack condition. For more information on self-discharge and battery imbalance see Why did my battery fail? What are my repair options if my battery fails? 2) Plug the device in to 120VAC 60Hz single phase power. The inverter pump clearly works, and there is noticeable flow. Charging cables are rated 10-A, 1,000V. 3E93EC41-5D49-4435-98DF-06A5B85606F6.jpeg, (You must log in or sign up to post here. What IS the maximum acceptable inverter temp?? Its the same as the Min Block PID, except it reports the block that has the highest voltage. A personal guide to the challenge of turning your dreamowning a Porsche 997into a reality. The most common code to get when your battery fails is PA080 (Replace Hybrid Battery Pack), its not uncommon to get a weak battery block code which are P3011 thru P3024 depending on which part of the battery failed. 12) Disconnect the charging cables and, after a minute or so, short them together for safety. We highly recommend that if you do choose to replace your battery on your own that you invest in a repair guide, research everything before you do it, and follow all of the safety precautions while working with your hybrid battery. Pressing the "Power" button will put your Prius in "Accessory" mode, placing a small load/drain on the battery. Our batteries come with a full 12 month replacement guarantee and will last at least 100K miles under normal conditions. This is the capacity imbalance that will result in the eventual failure of a hybrid battery pack. Never change fuses while the main power switch is on. If you can find a shop to install your maybe good battery it will cost you another $300 and they will not guarantee it because it wasnt their battery. 
Figure 4 shows a graphical representation of a batteries typical module capacity when we first test it. Figure 1 is an example of one module from a Prius battery. Compare that to the bad battery where the range was 18V to 14.5V. This indicates my battery probably needs replacing soon. Content is for informational or entertainment purposes only and does not substitute for personal counsel or professional advice in business, financial, legal, or technical matters. Figure 3. Send them to crphipps@aol.com, For a 10-amp, 220VAC input battery charger, click, For our entire line of high voltage hybrid battery chargers, click. Slowly turn the "Set Chg" knob further until the desired final voltage is set (using Figure 2). What happens behind the scenes will shock you. Press the trigger button and simultaneously step on the gas and brake at the same time. When you add all 28 modules together (7.2V x 28) you get a 201.6 Volt 6.5 Ah battery pack. The battery should last as long as the one that came in your car new, so that means you should be good out to the 350K-400K mile mark. 
1. If the voltage spike is large enough, a trouble code will be set to replace the battery pack. Its contacts will tolerate the transient voltage. Search Toyota Prius Torque News for more in depth Prius coverage from our reporter. On reaching set level +/- 1V or reverse battery connection. The fully charged voltage is just over 16V and drops to just under 15V. To Hondas credit, the bulk of them were covered under the standard or extended warranty. 3. 
However, please note that if the battery is completely dead and will not take a charge, it could be overheated if you leave it charging at 3A for hours. It can still be used to power accessory devices like cell phone chargers and the radio when the car isn't running or in "Ready" mode. 4) Turn on the HVDC switch. Let the sounds of a bad starter help you diagnose and repair your hard-to-start or no-start problem with your car. The length of the capture is five minutes, so each division is about 30 seconds. Tested the voltage on the 12v battery. 4) Greater safety, because the ammeter's internal terminals areat "ground" rather than high voltage. Your Prius has a Nickel Metal Hydride battery in it. 7) Turn the Set Chg knob clockwise until the alarm quits sounding and the charge complete green light goes out. There are advantages to having assembly done in a factory setting by a guy or gal that does nothing but assemble batteries all day long. How long should my original battery last? Have Minnesota Hybrid Batteries diagnose and replace your battery. So, for hybrid customers who want to know, It the battery in good shape?, I suggest the following. Find a used low mileage battery at a salvage yard and install it yourself or have it installed at a repair shop. Cells, cells, and more cells are what people continually say when discussing Toyota Prius batteries. For the voltage under load (when your Prius is in "Accessory" mode), anything below 12.0 volts is unacceptable, At the time of testing, when these photos were taken, I had just finished a long drive in my Prius so the battery should have been at a higher voltage than what I found above. Keep the device in a well-ventilated space. (Faster then I anticipated) As Im waiting for my scanner tool to come in from amazon, I did a little more digging. You should read the codes, you probably have another problem, not the battery. I used my racket till the bolts were tight and then a tad bit more, no specific torque. Once the MFD has booted up, press the "Display" button (red arrow) once. You may hear the battery cooling fan running on high (back seat on the passenger side is the intake for the fan). Safety: Other chargers use transformers (heavy and hot) or high frequency IGBTs [Insulated gate, bipolar transistors]. Its a 95 degree day but the fan is running constantly. Press these indicated spots (green arrows) six times in the order indicated on the arrows (i.e. 1) Make sure front panel switches are in the off position. Although damage will not always occur when it is not followed, proper operation may be compromised. The most common reason why hybrid batteries tend to fail is because of heat. The level of concern about battery packs is massively disproportionate to the actual rate of failure.

The charge rate is deliberately low so that there is little chance of overheating the battery. 12.3v resting 13.93v ignition on. The first option is to take your car to a Toyota dealership and have them diagnose and replace your battery. The maximum allowable difference is 1.2V. 
It also charges Camry, Ford Escape, Toyota Highlander, Lexus Rx400h, as well as Prius! Notice that the voltages come back together pretty quickly once the ICE restarts and the throttle is released. How to check them out. Those cells linked together give each module the 7.2v. "Do you need a motorcycle license?" (This is where the rapid charging and discharging symptom comes from, its not really the whole battery thats fully charging and discharging its just the weakest modules). Specifications of the top muscle cars from the '60s and '70s. 5) If the alarm sounds and the red panel light comes on bright continuously, you have the battery connected backward. Come check it out! Everything you need to know as to why you should buy a Ruckus is at your fingertips. But it seems that is not good enough for folks who are in the market for a used hybrid. So if you remember a module is six 1.2V cells for a total of 7.2 Volts. In the video, you will learn what a damaged wheel bearing sounds like and how to determine which wheel bearing is causing the noise. The inner modules will indicate full and empty very quickly because their capacity is so low, while the outer modules are actually doing very little. You will recover all of the lost fuel mileage that was being caused by your old battery being weak. Discover the causes behind the most common problems with your vehicle's lighting systems using this quick guide. There are about 7 divisions between the MIN and the MAX and each division is .5 volts. At the present time, the consequence in most Prius shops is installing a new HV battery, because most shops dont have an appropriate battery charger. There is an internal resistor which automatically discharges the capacitors in the unit after the power is turned off. All of the block voltages vary slightly. The test goes like this Start the car and allow it to warm up. Watch for drastically spiking voltages, and you will find your weak links. 4.The only way the attached battery could discharge is through 2kV of diode rating, 800V of SCR rating and an 800V capacitor. There is also a PID called Battery Max Block Voltage. Dim interior and exterior lights before starting that then brighten after putting the Prius in "Ready" mode. Loss of radio presets when turning on your Prius. The car is 7 years old, just like the other two Priuses that had bad batteries, but the mileage is considerably lower; this car has 58,000 miles on the odometer. Ive seen quite a few pretty poorly done resealing jobs. "120 MPG?!" 11) Turn off the HVDC and main power switches. With that being said, you should never block the intake to your batteries cooling fan. Regardless of the answer, I think 1.2V is a good good/bad cut point for battery pack testing. The air then flows thru the designed spaces between the modules and then out of the bottom of the battery case thru another piece of ducting that carries the heat out of the car. 
The red cable is plus and the black one minus! Batteries (or anything that conduct or store electricity) do not like to get hot. Check out this wild new battery tech that Tesla has and why it will forever change the auto industry. If you look at the picture below, a battery cell is the smallest part of the battery. 
If the IGBT fails, nothing stands between the battery with its 30kW output and the power mains. MFD screen on. What Is A Battery Block?

Any poor power or mpg performance with greater than 150,000 miles on your car should be considered a warning that your battery is not performing properly. Read more of Peter's stories at Toyota news coverage on Torque News. If one block in the pack is doing something wildly different than the others, somethings not right. Americans designed some superb sports cars in the 1950's and 1960's. This also results in low power, poor acceleration, and bad gas mileage. If the fan stops, do not use the device. I just found a nice way to graph it on the Techstream, and took some sample data on a few cars with known battery conditions one with a new battery, one with a bad battery, and one with a 60K / 7 year old battery that had no problems. For them, I have devised a method for testing battery condition. Your interest, opinions and questions. Get it replaced at your stealership, I mean, dealership. Always wear suitable high-voltage protective gloves whenever you are handling the high-voltage leads and clips or working near the battery. The actual R&R (remove & replace) is pretty quick. Anyway, I suspect that the fix saved some batteries and caused premature failure on others. Battery block performance can be affected by temperature and Im sure other variables as well. I've included pictures to assist you with this procedure. When we have agreed on delivery and you are sure you want to buy - - I will invoice you via PayPal. Peter Neilson is an automotive consultant specializing in electric cars and hybrid battery technologies. To keep it in top condition, you want to know all the steps involved int cleaning a car and keeping it clean. Charge voltage and current vs. time. I have turned off auto-ranging amplitude and set identical minimum and maximum scale values for both PIDs. A battery block is, you guessed it, two modules linked together. Every battery has an optimal temperature for those reactions to take place. (this is when it can be dangerous!). For our entire line of high voltage hybrid battery chargers, click here, Figure 1.The QDPC-160 Prius Hybrid Charger (July, 2013). That may seem like a lot, but its a drop in the bucket when compared with other types of expensive repairs.
