Noco G7200 does not seem to be have regular surface voltage measuring analysis of state of charge..
Friends new van with all bells and whistles did not start one fine morning. he called CAA ...after 20 or so attempts ( guys booster pack was discharged lol) they managed to start the van...he drove to office approx 12 kms
I joined him while back from office... van started well...we drove to my place 7 kms ..I told him how to use noco... then he drove his home another 5 kms at 6 pm..
he put noco...he said it took up to 1 am in the night to charge the battery to 100%
I am sure after this much driving , noco would definitely have found surface voltage to be full but still charged the battery...

It probably did find some surface charge but considering your friend's battery was empty, even with the surface charge, the voltage of the battery when the charger was connected was more than likely below the 'FULL' level. Surface charge is a real YMMV as it will depend on the condition of the battery and the time between ending the charge and measuring the voltage as well. Example - if a battery was empty and then charged to 50%, the surface charge will still result in a voltage measurement that is higher than what it really is. So, in this example, 50% is approx 12.2V on a lead-acid battery so you may see 12.5V after 10 or 15 minutes after charging it to 50% and then a few hours later, you might see 12.3V and then a few more hours later you get down to 12.2V. Now if the battery was FULL (ie 12.7V), then you may see 13.0V 10 to 15 minutes after charging, and then it drops to 12.8V a few hours later and then down to 12.7V a few hours after that.

One thing to note however, even with all of that driving, the battery wasn't full as he needed another 8 hours of charging before the charger thought it was full.

My car is 2012. The battery seems running ok except I remember there were several incidents that it took a couple times to start in the extreme cold days last year. Is it time to replace it anyway just to be safe ?

By the way, is it ok to get from Active Green & Ross or Canadian Tire ? Or buy it from Costco ? But then, I will have to install it myself ........

Thanks for any advice.

The first thing I would do is get the battery tested. If you are close to a Parts Source or Mr. Lube, they offer FREE in care battery testing. The test can let you know if all you need is a battery charge or if the battery is failing. If this is the first battery replacement since 2012, chances are that you may need a battery after 7 years. Sometimes the alternator may not be providing the full voltage because of a worn serpentine belt. This can happen on vehicles that are 7 years or older. Part's Source tester can also check the starter and alternator voltage and let you know if things are OK.

In terms of where to get the battery, Canadian Tire, Active Green and Ross and Walmart all sell the SAME battery (made by East Penn Deka) but each have slightly different warranties depending on the model. Costco Batteries are made by Johnson Controls which is also a good brand. What vehicle do you have (I am guessing 2012 Acura RDX by your nick name). If that is the case, are you comfortable installing it yourself and are you aware if you have to let the onboard system know that you have replaced the battery? Do you have the Radio code in case you have to key it in to get it to work? Start with reading the Owners Manual to see what group size, minimum CCA and other considerations you need to do.

If not, make sure that the place you take it to can take care of these issues. Alternatively, you can check with the Dealership to see how much a new battery is. Chances are it won't be that much more but at least these type of issues are taken care of.

Thanks. Yes, first time since I bought this 2012 Mazda5. I guess it is time to replace it. I know Costco would have the best price, but they probably won't have any appointment for installing it.....

If Canadian Tire, Active Green and Ross and Walmart all sell the same battery, I guess I need to find the one with the lowest price. AGR charges $50 for installation.

Can't install yourself?

yeah just install it yourself, size 10 millimetre wrench should suffice but bring a bunch just in case

If you have a 2012 Mazda 5, that should be easy enough to do. Here is a video on how to install it:


It takes a Group 35 I believe with a min 550 CCA and Walmart has a good battery with 640 CCA for $122. SKU 6000195362475

Use this site to find which store has the most stock in your area: https://stock.ga/

Just make sure that you get a fresh battery (sticker should say 11/18 or close to it) and you will be good to go. You can even ask the instore Mr. Lube to test the battery for free if you want. That is what I did.

I notice Canadian Tire says $20 additional for core charge. What does it mean ? The battery needs to be charged before use ? What about if I buy one from Costco ? Can I just put it in and start the car ?

Core charge is fully refundable if you give them your old battery.

Thanks. I just brought my tool and tried if I have all tools and can loosen all necessary bolts. I am going to get one from Costco and try. While I am checking the battery, I notice I probably need to replace the air filter too. Should I just get one from Canadian Tire ?

Yes the FRAM filter should be fine.

The Costco Battery link is: https://a.sellpoint.net//w/spworld/p.ht ... 0Selectory

The Costco battery looks pretty good as the specs are:

Warranty: 36-month Warranty with 100-month Pro Rate Included

Battery Specifications:

Cold Cranking Amps – 640
Cranking Amps – 800
Reserve Capacity – 100
Amp Hours – 57

BTW, while at Canadian Tire, get a battery cleaning brush, battery cleaner to clean the connectors, and a set of Battery Terminals protectors (RED and BLACKS pads) and put them on the battery terminals. That helps to prevent any corrosion. Also, don't forget gloves and eye protection as these things are bad for skin and eyes). Those battery cables might be dirty after 7 years and it is a good idea to get everything cleaned up nicely first. Also, check and clean the battery plate as well so that everything is nice and clean.

Please keep in mind that most places that will test batteries for free also sell batteries so they might not be completely honest with what your next course of action should be after the test. I always tell people to perform some basic maintenance on the battery (ie clean terminals, check/fill fluid levels - if possible, and charge the battery) BEFORE getting it tested so that the battery is in the best possible condition for the test. By doing so, you will know that there's little to nothing that can be done to improve the battery's performance at that point and the battery test will confirm what that is.

If you use the battery brush, you probably won't need the battery cleaner. The brush will mechanically remove the top layer of metal off the terminals leaving a clean smooth surface for the battery clamps to connect to. I would also apply a thin layer of dielectric grease (typically sold for tune-ups) to the terminals before connecting, and then another thin layer to the clamps to help prevent corrosion.
