Imagine paying installation for a battery when it's easy to swap out LOL. But honestly all Honda batteries do last 2-3 years (p/n 31500-TBA-H650, $152+gst for Civics incl CTR excl Clarity, Insight, Hybrid)

I just tuned my car for the first time. Battery drained enough while in accessory mode flashing the tune that it wouldn't crank after the flash. Had to jump start it. Couple days later, I switched from a base Ktuner tune to TSP Stage 1 and same thing, needed a jump. Guess I'm going battery shopping soon.
Use a battery tender while flashing a tune because reprogramming the ECU is battery intensive.

Happened to me on the Honda battery and was tied back to a partially failed core. The battery (Honda or aftermarket) "should" be good up to 6 hours running in acc (about 1/4 of that in ready).

I have a portable jump starter that I got for $40. Worth its weight in gold.

The last two times I have gone to start my car. Nothing. Completely dead. And this is my second battery. 36k miles. Something is drawing power or I don’t even know. I’m inclined to say it is something with these cars rather than the batteries. Or maybe in addition to the weak batteries. My current battery is the Costco Interstate battery mentioned elsewhere in the thread btw.

I just replaced my battery at 35K but this car has lived through a summer in Florida and 2 summers here in Vegas. Heat just ruins batteries.

Mine was dead after about an hour in acc. It also seems to die after a week of just sitting.

I've had my car for 3 1/2 months, and since we just started getting some mornings in the 30's, it seems to turn over more slowly and take longer for the car to start, already.

I've never seen a battery show weakness this early.

Not normal. Take it in & have the dealer check it. Honda battery is 3 year warranty with free replacement if defective. Check should also be free even if the battery is good.

My battery just DIED went bad at 2900 mi (20 months old). Honda replaced it under warranty and tried to upsell me on "battery maintenance" as the old battery leaked acid on my cables (I had to pull of my strut bar before taking it in so I know there was no acid leak) - Stealerships

BTW the best car battery hands down is sold at AutoZone: Optima
Got a D51r-T1. Just needed thicker shims. Works fantastically!

My battery lasted from Dec 2015 until today - 55,000 miles. I guess I did a little better than average. But my Civic is in a heated garage overnight, so that may have helped extend its life a little.
