11th Generation Honda Civic Battery 31500-TLA-EFB100M Cold Weather Failure

[Civic Lover]

I have a 2022 Honda Civic Touring with 13,126 miles on June 11, 2025, that needed the correct Honda Battery since my kid got into an accident in May 2025. The collision repair shop installed a cheap AutoZone battery that was a smaller size and had much lower CCA. Incorrect type of battery.
Gone to the Honda Dealership where I purchased the Civic to get the correct battery 31500-TLA-EFB100M MSRP $266.83, Labor $20, Core $16, total cost $302.83.
Took the AutoZone battery back to the collision repair shop and was reimbursed the money that Allstate Insurance paid the collision repair shop.

Went to a closer Honda Dealership, On Oct. 7, 2025, my Civic was due for State Vehicle Inspection and Oil Change in Oct. having 15,260 miles. The Civic needed new Fog Lamp Inserts to replace the cracked ones. The Civic was left at the Honda Dealership for the weekend awaiting the plastic inserts to arrive on Monday. Monday came and the Civic would not start. The Dealership pushed the car into the service garage and ran a long battery diagnostic test for a Failure Code so it could be replaced under Honda warranty. This way, the Dealership can be compensated/paid for the battery and labor if it fails. Unfortunately, they could not get a failure code and said the battery was good. My cost $0 for the Battery test.

Just after Thanksgiving Day, we had snow and getting colder. The Civic did not start in the morning. Took the battery charger to the car and waited 40 minutes and it started. I was too lazy to bring my 2023 Toyota Camry XSE V6 around to use jumper cables.

I went online to Amazon and bought myself the Wolfbox MV24 4000A Jump Starter for $110. Glad I did. 3 more times here in December 2025, I had to use the Wolfbox when temperatures dropped below 25 degrees farhenhiet. Last draw, enough of this BS and called the Honda Dealership where I purchased the Honda battery from. Took it in today December 12, 2025, and it failed. The Test Code given: 85J2S-THXSX. No reference for the test code failure other than a bad battery.

The Honda Dealership replaced the faulty former new Honda Battery they installed on June 11, 2025 with a new one. However, the ECM did some weird things as the Instrument Cluster/Dashboard started showing many ICONS/Symbols after driving 20 minutes. I stopped, turned the car off and restarted. The Icons/Warnings all disappeared. Did not cost me anything but gas and my time.

You can still have car problems even after getting a new Honda 31500-TLA-EFB100M battery.

The Winter season is here. I am hoping not to encounter any more problems with the Civic due to cold temps.

I regularly read here, but not often, about battery problems experienced by American Honda owners.
I get the impression that this part is really different from those installed in Hondas manufactured in Canada.
Or Canadians Honda owners are not sufficiently present on the forum?
My wife's 2016 Honda; original battery.
My 2018 Honda replaced in 2024; original battery.
And my current 1.5-year-old Honda; original battery.
These cars have always started in the cold Canadian weather.
Our old Toyotas replaced after 10 years; original batteries.

Or you have an accessory that continuously draws power and drains the battery. Have there been any electrical modifications to this car, such as an amplifier, speakers, or other devices?

The battery applies to the 11th Generation Civic (2022 - 2025) 31500-TLA-EFB100M it replaced the discontinued 31500-TLA-A11 battery, My 2022 Civic Touring was made in ALLISTON, ONTARIO, CANADA. and shipped to Buffalo, New York, USA.

Yes! It could be possible to have a defective new battery. Nothing is perfect or guaranteed.

HAPPRY NEW YEAR 2026

It's actually normal after swapping out the battery, as the car's systems need to recalibrate.

As for the stock Honda battery, I'm not surprised. I opted to swap mine out to am AGM with better CCAs after seeing what I thought was battery acid.

Not a single add on electronic device or vehicle modification. 2022 Civic Touring was involved in an accident in March 2025. Collision shop decided battery was bad which had no issues prior. There was only body molding or cosmetic part replacement, no major damage of any type but yet collision shop removed it and installed some crappy underrated CCA and smaller sized battery from AutoZone. I had Informed Insurance Company, they paid me for a new Honda Civic battery which the Honda Dealership ordered and installed in June 2025. By November 2025 when temps dropped Civic would not start. In December had the battery tested and it was bad. Had a new Honda Battery installed again. No Problem as of Jan. 5, 2026 and had temps in single digits.

Honda does not support AGM in the 2022 Civic Touring
The OEM battery for the 2022 Civic is explicitly listed as EFB (Enhanced Flooded Battery), not AGM.

2022 Honda Civic Touring’s charging system is designed for an EFB (Enhanced Flooded Battery), and Honda does not recommend installing an AGM battery because the OEM battery type is EFB

If your Civic has Idle‑Stop, the EFB100M is the safest and most compatible choice.

Honda Parts Now explicitly lists the A11 battery as “discontinued” and replaced by 31500‑TLA‑EFB100M

The newer EFB100M is identified as a Clarios-built LN2 EFB battery, while the A11 was an older LN2 design.

31500-TLA-A11 has 450 CCA / 57Ah is Discontinued replaced by EFB100M which is also being Discontinued.

31500‑TLA‑EFB100M has 640 CCA / 60Ah NOTE: Honda has Discontinued this battery but available at various online Parts Stores or Honda Dealerships. No replacement found.

I wish you good luck with you new battery .

Has a test been carried out on the car's battery-powered circuit to confirm that no abnormal current is flowing when the car is stationary ?

There will always be a few hundred (?) milliamps flowing to power some of the car's circuits, but if there is too much current, this could contribute to destroying the battery.
