Which Car Battery is Best? Let's find out!

it just seemed like a couple of years ago I could purchase a car battery for under hundred dollars but for this video everyone except for one of the car batteries we're testing costs over $100 in one of them cost over $200 where the car batteries get so expensive and if you're gonna pay that much money for a car battery you want to make sure it's going to last so let's get the testing underway and see which way these car batteries is the best in the first test we're gonna see which brand produces the most cranking amps at seventy-five degrees Fahrenheit we're also going to place a load on these batteries to see how they compare we're also going to compare absorbed glass mat batteries with flooded lead-acid batteries to see if one type of battery charges faster than the other we'll place these batteries in a freezer for 24 hours and then measure the cold cranking amps Before we jump into the testing we'll compare a total of 6 batteries for our flooded lead-acid batteries which are the most common type of battery and two of them are absorbed glass mat batteries I'll explain more about each type of battery as well as the pros and cons of each type of battery later in the video I purchased all these batteries on the same day but all of them need to be topped off to be fully charged I'm gonna go ahead and charge all these batteries using a 750 milliamp trickle charger that's safe to use on both flooded lead-acid as well as absorb blasts Matt batteries all the batteries are now fully charged and have been disconnected from the trickle charger for several hours so let's begin comparing each of the brands the least expensive battery we'll be testing is this ever start sold by Walmart costing only $119 in 76 cents group size 27 and 810 cold cranking amps includes a five-year warranty or a three-year free replacement the Walmart ever start battery is bathed by Johnson Controls 810 cold cranking amps and a thousand cranking amps at 32 degrees Fahrenheit the first test compares to cranking amps of each battery at 75 degrees Fahrenheit so we'll select CA on the meter for cranking amps in order to get cold cranking amps the batteries have to be at 0 degrees Fahrenheit to get an accurate reading the Walmart ever start is off to be pretty good start at twelve point eight eight volts in 1115 cranking amps in case you're not familiar with internal resistance it's basically a measure of how efficient a battery is at delivering high current on demand for a new car battery anything under five is great the internal resistance is only three point four eight millions which is actually pretty good costing $40 more than the Walmart battery is this Duralast golde which cost 150 $9.99 Johnson Controls makes both the ever start max as well as the Duralast goal just like they ever start this one is rated for 810 cold cranking amps however the Walmart battery is rated for a thousand cranking amps and this one's only rated for 930 the interstate battery is also made by Johnson Controls and it is exactly the same everything on the ever start in the dirt last batteries looks identical except for the stickers on the outside that's hoping the dirt last would perform just as good as the ever start since I paid $40 more for it compared to the ever start but it didn't it only produced twelve point eight volts and a thousand and twenty two cranking amps with an internal resistance of 3.8 for the ever starts internal resistance was better at three point four eight Costigan hundred $39.99 is the Super Start premium battery which is sold at O'Reilly East pen manufacturing it makes this battery group size twenty seven eight hundred and forty cold cranking amps well it's not listed on the battery it also provides a thousand and thirty five cranking amps the O'Reilly Super Start battery produced 1133 cranking amps in twelve point seven eight volts it had an internal resistance of three point four two milli ohms which is slightly better than both the Walmart and the AutoZone batteries costing hundred thirty nine dollars and ninety nine cents is this auto craft silver which is sold at Advance Auto Parts this battery is awesomely by Johnson Controls the auto craft silver comes with a two year full replacement warranty instead of going with a third battery made by Johnson Controls group size twenty seven I went with the group size 3478 in order to compare this against the Optima battery as well as the die hard which are both a GM's I wasn't able to find the AGM batteries configured in group size twenty seven the auto Kraft silver is rated for a thousand cranking amps and eight hundred cold cranking amps the auto Kraft battery from autozone and made by Johnson Controls produced twelve point seven eight volts and 1083 cranking amps it had an internal resistance of three point six which is good but not as good as the O'Riley SuperStart battery the most expensive battery we'll be testing is this optimal red top costing two hundred and twenty four dollars and ninety nine cents it is rated for a thousand cranking amps and eight hundred cold cranking amps and this is group size 3478 the opera it's made by Johnson Controls it comes with a three-year free replacement warranty unlike the other batteries we'll be testing this is an AGM or an absorbed glass mat battery the optimum produced twelve point eight four volts in 1125 cranking amps now AGM batteries are supposed to have lower internal resistance than flooded lead-acid batteries so let's see if this is true so the internal resistance is only two point seven six milliohms very impressive just like the Optima this diehard advanced cold battery is also an AGM battery dart is a Sears name brand however this battery is made by inner sis and this also makes the Odyssey brand AGM battery it includes a three year for your placement warranty let's see if the diehard can beat the Optima the diehard produced 13.04 volts in 1148 cranking amps just like the Optima this - as an AGM battery and actually did slightly better than the Optima with an internal resistance of only two point six nine milli ohms we're gonna use the car battery as well as the inverter to power up this light for thirty minutes to see how each battery performs I'll be keeping an eye on energy consumption looking at this kilowatt device also this power inverter provides us with some great information regarding the voltage being produced by the battery this next test is placing somewhere between 42 and 44 amps of load on each battery for 30 minutes which is a pretty tough test and will give us a great idea on how well these batteries can handle a long heavy drain fortunately all of the batteries survived the test just fine and the low voltage alarm on the power inverter wasn't needed this time car batteries have six cells and each cell is at two point one volts at full charge a car battery is considered fully charged when it has a voltage above twelve point six at twelve point four volts it's not fully charged but it's still considered charged below twelve point four volts the battery needs to be recharged let's see what that long battery drain did to the batteries I've allowed the batteries to sit overnight so let's go ahead and compare their performance the O'Riley super start is at twelve point four seven volts and 1044 cranking amps it actually did pretty good and still has a strong enough charge to start a car you ever started is at twelve point five nine and 999 we're over twelve point six volts is considered fully charged so this battery actually did great the Duralast is at twelve point five three and nine hundred nineteen and didn't do quite as well as the Walmart ever start battery the auto craft is at twelve point three four and nine hundred and twenty so it's below twelve point four volts and definitely needs to be charged so it do quite as well as the first three batteries the Optima is only at twelve point two six volts and 964 amps this battery definitely needs to be charged the diehard started off a little bit higher than the others at thirteen point one volts and drop to twelve point four nine volts and a thousand and thirty-two cranking amps do some batteries actually charge faster than others what we're going to do is put a battery charger on each one of these batteries one at a time for one hour using the 10 amp setting with the lower internal resistance than the flooded lead-acid will the AGM batteries also charge at a faster rate let's see how much a voltage increase each battery experiences in just one hour at 10 amps of charge The O'Reilly Super Start started off at twelve point four seven volts and is up to twelve point seven eight which is a point three one volt increase the ever start started off closer to fully charged at twelve point five nine and increased to twelve point eight three a point to four increase the Duralast start off at twelve point five three and increase to twelve point eight one and increase of 0.28 volts the auto craft started off at twelve point three four and increased the twelve point seven two volts an increase of 0.38 vaults the optimist started off at twelve point two six and increase to twelve point seven to an increase of 0.46 vaults the diehard start off at twelve point four nine and increased the thirteen point zero one which is a point five to increase the most of all the batteries we tested so both the optima and the diehard which were absorbed glass mat batteries did charge faster than the flooded lead-acid batteries even though the ever start didn't experience as much of a voltage increase it also started off at a much higher voltage than some of the other brands and ended up at a higher voltage than most before doing a cold cranking amp test I'm gonna go ahead and top off each one of these batteries using a turbo charger now this trickle charger is designed for both flooded lead-acid as well as AGM batteries all of our batteries have been topped off using the same style of trickle charger baseline numbers before putting these batteries in a freezer and then we'll come back and see how they perform once they are right at zero degrees Fahrenheit this next test will be placing each one of these batteries inside this freezer and leave them in there for 24 hours and then we'll be testing the cold cranking amps to see just how good each one of the batteries performs the temperature inside the freezer is minus 14 degrees Celsius which is very close to zero degrees Fahrenheit so let's go ahead and begin the testing the Super Start is rated for eight hundred and forty cold cranking amps only produced seven hundred and 45 the ever start is rated for 810 and only delivered 766 which is still much better than the superstar the Duralast is also rated for 810 cold cranking amps and only produced 753 the auto craft is rated for 800 and only produced 725 the Optima is rated for 800 and produced 751 that's the second best compared to the ever start the die hard is rated for 775 and only produced 697 so if you don't take into consideration the cold cranking amp rating x' and only look at which batteries produce the most cold cranking amps the least expensive battery the Walmart ever start one the cold cranking amps another way to look at it is how many cold cranking amps each battery delivered below there cold cranking amp rating so looking at it this way once again the least-expensive battery the Walmart ever start one however the most expensive battery the Optima wasn't too far behind we're gonna place these batteries back in the freezer now and we'll come back in 24 hours to see how they perform at 20 below zero the phrases at minus 27 degrees Celsius which is very close to minus 20 degrees Fahrenheit so let's go ahead and get the testing underway to super start delivered 683 cold cranking amps and the internal resistance was at 4.6 the Everlast produced 780 cold cranking amps and internal resistance was 4.45 which is better than what the superstar achieved the Duralast was also at 708 cold cranking amps and just like the ever start was at 4.45 for the internal resistance the auto craft only produced 651 cold cranking amps and the internal resistance was at 4.8 to milli ohms the optima is only at 629 cold cranking amps but it had the best internal resistance at 4.16 the thai hard really struggled at 580 cold cranking amps with an internal resistance of 4.5 million this time around did he ever start as well as he Duralast both tied for the first spot at 7 ornate cold cranking amps the super start wasn't too far behind at 683 another way to look at it is how many cold cranking amps each battery delivered below there cold cranking yeah parading once again the least expensive Walmart ever start as well as the Durr lasts in this case both tied for the top spot while this was a really tough test I really thought the AGM batteries would do a little bit better so which batteries you buy for your vehicle if your vehicle uses a flooded lead-acid battery like the first four batteries we tested I would continue using a flooded lead-acid battery who would buy either a Costco interstate battery or the Walmart ever start if their prices are the least expensive after all why pay the extra forty to sixty dollars for a battery that's made by the exact same company and just sold at a different place well we didn't test that the Napa's battery is also made by East Penn manufacturing but cost more money and has a lower cold cranking amp rating so the O'Reilly Super Start battery seems like a better option than the napa battery if your car has a factory equipped absorbed glass mat battery you'll probably want to continue using one the handle vibration better don't require any maintenance handle deep discharge is better but they are going to cost quite a bit more if you live in an area that doesn't get below freezing I really like the performance of the die hard better than the Optima however if you live in an area that does get below freezing the Optima definitely seems like a better option I really like it when I find opportunities to save money and in this case it proved once again you don't have to pay more to get more in fact you could pay less and get more when you buy a product such as the Walmart ever start which is made by Johnson Controls as it turns out Johnson Controls makes well over half the batteries manufactured in the United States now just as a reminder I buy all the products tested on this channel and I say no to every single sponsorship opportunity all the videos on this channel our viewer recommended including this one so if you have a video idea please let me know and there's a good chance I'll put together a video on it as usual thanks so much for watching the video please take care and I look forward to next time
