I just got a new car battery. Dead already.

I also have short drives and occasionally plug in my car battery to keep it topped up.
How long did it take for your new battery to fail?
You'll need to check everything to make sure nothing is drawing any current. One way is to lock yourself in the car at night and be sure that all lights go out, including in the trunk.
You can also measure the current draw at idle from the battery using the appropriate meter.

Well, the semi obvious answer would be to get your charging system tested to make sure it's putting out enough juice to charge the battery. You don't mention anything about that.

I live in Winnipeg and it's been cold, but not THAT cold. I keep my block heater plugged in when the temp gets -15 or below.

I only occasionally drive my car and take short trips only (15-30 mins), usually. A few times a week. Sometimes my car sits unused for a few days.

Could it be my remote starter? Or some other drain?

I just bought a trickle charger. But if anyone has any other suggestions that'd be great.

My old car Acura TL had battery drain and later I found out the fan didn't turn off completely after I turned off the car, had to get it fixed.

After market stereo? Bad alternator?

The battery on that generation of Fit is tiny.
151R is the code and it's around 350CCA.

15-30mins probably isn't enough time to charge it especially if you don't consistently rev it high enough like on highway.
Put it on a tender or just charge the battery overnight biweekly. it should help.

I advise my friend with a 2016 Fit to drive it daily, especially in Winter because of this. And you want to keep it charge in winter or it may freeze.

3. Not sure if that applies to 2013 model tho.

your alternator is toast.

Start the car and let it idle for a bit, then take a multimeter and read the battery terminals.
It should read between 13.8 to 15.3v(according to the web). That'll tell you if your alternator is working or not.

How old is the battery you bought from CT? Although likely not the cause of your problem, I wouldn't necessarily trust CT selling you a fresh battery.

I ordered an Energizer AGM battery from costco.ca with the $20 off $100. This was in late November.

What came to me was one manufactured in May. It's probably the distributor that sold and shipped to me. I guess I won't have any missed feeling returning the battery for 100% once I scrap my car lol.

Go to a partsource store when it’s not too busy and get them to do a free battery test (It’s an in car test, they come outside to do it with the battery in place. You don’t have to uninstall the battery)

There's something wrong with OP's car. Either a parasitic draw, or insufficient charging from the alternator.

No, it's One-Five-One R. The one on the right.
51R is used on Civic and up.

My friend's 2016's battery is about 2 years old when he brought it to my heated garage for winter storage while he was out of town. I was surprised it ran out of just after just 2 weeks of storage. Not sure where the parasitic drain is but boost and he is running ok every since.

I stand corrected.

Damn that's small. Is there room to upgrade to a bigger battery?

Have to cut the battery tray or take off the tray and clamp down with the hold down bar.

The 151R is a small battery but perfectly adequate for the Fit as long as you don't have a charger/alternator problem or some kind of parasitic drain as someone has mentioned.

Thanks for the replies.

When I bought the car used it had a 51R Interstate battery in it, it was modded to fit. But that battery was 3 years old already, and it drained 2 separate times when winter came. So that's when I went to Canadian Tire to get a new battery, and I was under the impression they were going to put the same size big battery in. Looking at my bill from CT now, they did indeed put a 151 MOTO battery in there, not 51R. I was confused when it took them about 2 hours working on it and the guy told me they had trouble putting it in and a "tray" was missing. You might notice I know nothing about cars, I was just happy to have a working car again, or so I thought.

So as far as I can tell I screwed myself by going to CT and downgrading to a smaller battery. But it cost $140 + labor so it's too late now.

OK so from the advice here, check alternator first.

I also bought two different trickle chargers, just in case the problem is just that the battery drains because it's cold and I rarely use it:

https://www.amazon.ca/gp/product/B0051D3MP6/

The solar one I got so I can keep it on my dashboard and keep it plugged into the DC port. My car is kept outdoors.

Should I take it to a mechanic or buy a multimeter to check the alternator myself first?
