Cruze Battery Upgrade Options

I had this discussion with bartonmd on the FB group earlier today and he provided a few options for battery replacement upgrades over what we have from GM. As you guys may know, the 1.8/1.4T battery tray is adjustable and has plenty of room left for a bigger battery.

Here are the specs for the OEM H5/47 group size, from an AutoCraft Gold battery:

H5/47:
520 Cold cranking amps
7.5" Height
9.57" Length
6.938" Width
Weight: 45 lbs
Price: $161.99

The following two group sizes fit in our battery trays. Here are the specs I found for the Advance Auto AutoCraft Platinum AGM battery. I strongly recommend any AGM battery. I've posted the differences over the OEM battery (assuming the AutoCraft Gold is equivalent or similar) in bolded green. The CCA specs and prices will vary slightly but not by a whole lot.

H6/48:
760 Cold cranking amps (+240 CCA = +46%)
7.5" Height
11" Length
6.938" Width
Weight: 45.66lbs (+0.66lbs = +1.5%)
Price: $174.99 (+$13 = +8%)

H7/94R:
850 CCA (+330 CCA = +63%)
7.5" Height
12.44" Length
6.938" Width
Weight: 51.83lbs (+6.83lbs = +15%)
Price: $187.99 (+$26 = +16%)


Here is what the OEM H5 battery looks like in the battery tray:


Here is what the H6/48 battery looks like in the battery tray:


Here's a picture of the H7/94R battery in the Cruze:



Remember, if you have an Advance Auto Parts store near by, there is almost always a 30% coupon available that will knock $50 off the price of a battery. Order online to pick up in store.

Does anyone have an opinion about replacing a standard lead acid battery for super capacitors in parallel.
Only if they are sold for that application. Capacitors and batteries are two very different animals. Do a Google for "capacitor discharge curve" and "lead acid battery discharge curve" and you'll see what I mean. A battery holds it's voltage as it's capacity is used up, but a capacitor drops like a rock.

12.1V looks to be about 50% of charge. Now, that could be high discharge (perhaps self-discharge), or failure to be charged. Can't tell.

At this point, I'd say it's cause for some concern, but it's not pointing to what is wrong.

Note that after shut-off, the battery voltage will be high due to surface charge.

Is that something that can be addressed with B2B warranty?
Good question. What I'm reading for the 2016 warranty is that it's only covered for 12 months. I guess the battery is considered something of a consumable. OTOH, I think I've read where others were covered under B2B. You probably should check the one you have.
