I have the original battery in the car. It is a type 31500-tla-a11 en ln2. I have had no problems with this item but considering it’s 4 years old I wondered if I should think about replacing it. Honda wants an outrageous amount to do the job and I know I can do it myself. Called around for battery pricing and when I entered my car info I got a listing for an AGM battery H5-AGM. Is this a correct replacement For the OEM battery? Do you agree that it’s wise to replace the battery. The car has only 14500 miles on it.

Welcome to the CRVOC forum. Many fine folks here from around the globe.

Click on your avatar in the upper right hand corner, —> Account Settings, —> Vehicle Details. Complete for your vehicle, then hit Save. In this manner, that vital piece of information automatically appears whenever you post.

With 6 generations of the V on the road today, knowing the year & trim level of the vehicle in question helps those asking & those willing to respond.

H5 -AGM I believe is the correct size for your V. When I replaced the OEM battery in our '18 V, that is the size I purchased. [Of interest, in the 2023 Accord, the battery size is H4.]

As your OEM battery is close to 4 years in the vehicle, get your entire electrical system evaluated by an automobile electric shop - battery, alternator, etc.. As many here on the forum will attest, 4 years appears to be the age limit for OEM batteries.

What is the normal type of driving that you do with this vehicle? Many short trips, I.e. 10 miles or less, will not give the alternator much of a chance to recharge your battery.

If short trips are the norm for you, one way to insure a long battery life is to take your vehicle out for a highway run at least once a week for at least an hour at highway speeds.

Another way to insure a long battery life is to purchase & use a battery tender. Use the Search Community box located at the top of this post to find out which battery tender is recommended by forum members & how they utilize it.

Good luck. Keep us posted.

We have the same car, except with 50,000 miles on it. Still on the original battery with no issues. 4 years is not an indication of imminent failure. My 2009 Honda Ridgeline's original battery lasted over 9 years. It didn't fail but I replaced it proactively due to the upcoming winter.

Have it checked if you're worried. As said previously, the way you use the car has a lot to do with battery longevity. These newer vehicles have more electronics and things like electric power steering that may affect battery life also.

Mine is an '18 CR-V which tests 100% state of health and 100% state of charge with my SOLAR conductance tester (Amazon). My smart battery charger is always plugged in and connected to my battery when the veh. is not in use. Why would you abandon a perfectly good battery. Maybe you should test it more frequently & smart charge it the same way.

I had the battery tested and the technician said it was fine. He suggested this type of battery usually lasts longer than the older style, maybe 5-6 years. As mentioned I am having no problems with it. The cold temps got me nervous since I have on previous vehicles gone through the experience of going out to start up and getting nothing due to a dead battery.

That was a good thing to do. Now invest that unused battery replacement money into a (smart battery charger) and use it frequently. Mine is called Ultra Pro Elite and I bought it at Costco about two months ago. I don't see them for sale at Costco anymore bit it was on sale for $39.99. Get a good one and it will take care of your batt.

Certainly take it to any auto parts store for free testing anytime you like. You don't need to regularly 'load test' your batt. A conductance tester will give you the info. in % of health & charge. These percentages are useful to know for replacement purposes. Starter health & alternator health are testing options too with this device. My SOLAR was only $50 from Amazon but that was five years ago. The C. tester works even when the batt. is not fully charged.You will need to input some data like Cold Cranking Amps for your specific batt. and it's type, (SLI-start,light,ignition) in your case. AGM batt. charging is another option. Should you need assistance understanding all of the various readout numbers, just reply here and someone will respond. If your battery tests good the C. tester simply reads "OK." Easy peasy! Keep in mind that 12.6 volts is an average fully charged battery voltage. Alternators put out at least that much to charge or maintain your batt. while driving. Sometimes alternators put out up to 14.5+ volts for recharging. The smart charger will help to preserve your alternator by reducing the alt. charging load. Keep up with your other maintenance and use a PEA based fuel injector cleaner like Chevron Techron "Complete" every 3K.

I've had great service out of AGM batteries, and they hold a charge for a longer period than lead acid batteries. A battery in a vehicle that is infrequently driven can fail earlier than one driven on a daily basis, at least in my experience. Four years is fairly decent service life. The AGM in my civic is 7 years old and doing well.

I would test the battery every 6 months or so and replace it when it starts to get weaker. These newer vehicles are more sensitive to batteries in failure mode than the old cars, due to all the electronics.
