Original battery just died at 50K miles. it is the 1.5L with a 51R battery. What are the current recommendations for replacement. Can anyone tell me what battery is used in the newer 1.5L (not the stop/start version). I googled and found many conflicting recommendations on replacing this battery, so I am looking for an update with fresher information. especially from someone who may have recently explored this. Thanks.

The current battery just failed at 4 years, out of the blue. No warning or previous issues. The car wouldn't start, and when I connected my handly start pack to the battery, it indicated the battery had failed and it refused to start the car, so it's sitting on my old car charger for now. I imagine tht batttery it toast.

2017 CRV EX-L Turbo with Nav. Took me 3 Honda battery to get one that worked right. The 2nd one died with no warning--bad cell. I just replaced my "good" battery when the service test said cranking power was down about 20%. It was 26 months old. In 2 years the cost of a Honda battery has gone up about $35.

It probably would have been good for awhile longer but I don't have time to take the chance. I put in another Honda battery but at my next Costco visit I saw that they sell Interstate batteries. I think that the next time that I need a battery I will have an Interstate battery installed and see if they do better.

I put a DieHard in my 2015.. A bit pricey but I had really good luck with them in the past.

I got 33k miles out of my '18 OEM battery. Got the Interstate at Costco for $89. but had to put it in myself. It took about 1/2 hour, but when I restarted I got a ton of error messages. I turned the radio on and found instructions to idle the car for 10 minutes while GPS signals sort out the computers. After 20 minutes, no resurrection, so I decided to drive it down the street, and in about one more minute, everything reset and I was good to go. I did have to push the ECO button, as the default is regular operation. So I went from 36 MPG to 27 MPG for about 10 miles! I changed the FOB battery so I'm good to go to maybe 60k miles.

If you have a AAA membership buy a battery from them. They have a 6 year warranty on them. The first 3 years is a complete replacement and the last 3 years you pay a small fee for the replacement. They have good batteries and keep all your purchase information so you don't have to go hunting down receipts. Plus, they will come to you to replace the battery.

Batteries fail without notice. This subject has innumerable threads here at CRV owner's club. Many people -- including me -- have said that the first sign of a weak battery was when it flat out would not start the car. Happened to me in the parking lot at Walgreen.

A guy on youtube tested a bunch of different make batteries and concluded that the Walmart Everstart Maxx is the best buy. I got a group 24F (CCA 750) for $99. You don't have to buy a new battery tray if you don't want to. Just cut the sides off the OEM battery tray. Either get new longer J-hooks, or (what I did) get a battery strap like they use on boats. All in the same rack at Walmart.
Walmart has a great warrantee on the Everstart Maxx barreries.

At the time I bought the 24F for $99, Walmart had the 51R for $120. CCA 500. The 24F was a no-brainer.

I'm going to have my late 2018 CRV's OEM battery tested - but it sounds like it will be coming due for replacement soon. My 2014 Ody with 100K miles still has its OEM battery and STUNNINGLY - my 2004 Volvo with 154000 miles is still on its 2nd battery - which (knock on wood) is still going strong after 12 years. Sounds like the newest cars won't see that sort of battery life anymore.

Thanks for the link. But the Interstate battery finder at that link does not offer an AGM battery for the 2018 CRV. What brand AGM did you find?

If your battery is the factory original it is a 410CCA battery. So maybe the 442CCA is a really good number or a fabrication.

My original battery from 02/17 was replaced under warranty after 18 months with a 500CCA Honda battery.

In my opinion, your battery is living on borrowed time.

Normally, a good battery under a CCA test, will measure a CCA result that is roughly 120% of spec value.

So, a 410CCA rated battery should read at 470-490CCA at 70 degrees F. CCA will decline as temperature declines, but gen5 CRVs are really low demand on a battery for engine start. A 410 CCA battery is over twice the CCA capacity required to actually start the engine.

His is a bit below 120% of spec, so as I noted earlier... it looks to have about 6 months life left in it... so the owner needs to keep a sharp eye on it until it is replaced in the near future. Once CCA begins to decline, unless the battery is regularly put on a smart charger (which results in modest plate reconditioning as part of the charge cycle) it will continue to decline in CCA by about 5% per month once it turns the corner on it's life and begins to fail. Regular use of a smart charger/maintainer can add years to the life of a battery that would otherwise fail if ignored... fail at about the 3 year mark in fact.

Just to note... owners of the newer CRVs (2020 and 2021/22) with the big H5 class batteries in them, and auto start/stop.. should avoid AGM batteries.

Reason: Enhanced Flooded Batteries are purpose built for the very high demands posed on a battery from auto start/stop vehicles. They also have more robust plate designs and will generally outlive an AGM, and are less expensive, but more expensive than the traditional flooded cell batteries.

EFBs are the wave of the future for the era of high demand vehicles with auto start/stop and tons of electronics. They are deep discharge capable, like marine batteries, and they are rated for more than 250K engine starts, which regular flooded cell and AGM batteries cannot even come close to achieving as they can only go about 30K start cycles before plate damage gets out of hand. EFBs are also sealed units, so no issue with electrolyte evaporation either.

 

[dbier]

After reading about the EFB batteries - I found this one that is a direct fit for my 2018 CRV which uses a 51R battery. Seems like a good option if you don't want to make adjustments to fit a larger H5 battery now used by Honda in the CRVs: https://www.autozone.com/batteries-...tery/p/duralast-platinum-efb-battery-51r-efb-group-size-51r-500-cca/1070704_0_0

Could you post or send a picture? thanks

Could you post or send a picture? thanks

I too would like to see a picture of the larger 24 F battery installed without a new tray. Meanwhile, this appears to be the Walmart 24F - 750 CCA battery he is referring to:

General comment for all owners, not just your specific post.....

Just to note, this AGM is not a great replacement for an existing 51R. Note the low CCA. And, unless you are actually doing off road driving or other rough road conditions, you do not need a glass packed electrolyte in your battery, so why pay the high premium for AGM.

And whatever you do, I would advise against putting an AGM into a CRV that uses auto start/stop... due to low life cycles for starting engines compared to batteries actually made for the purpose, unless the particular AGM has been spec'ed for use in auto start/stop applications.

A better choice, if you want to stick with a 51R, is go with an EFB version spec'ed at 500 CCA or better. EFBs are very rugged in precisely the areas of battery design where CRVs put the most demand on the battery..... the plates, the ability to be deep cycled due to neglect and low driving use, and over 250K engine starts in the life of the battery. EFBs are also generally fully sealed too, so they will not dry out under any normal driving and use conditions.

I have only found one EFB 51R (at Autozone) and it is only 435 CCA. Have you found one with 500 CCA or better?
CORRECTION> THE EFB 51R AT AUTOZONE IS ACTUALLY 500 CCA - SORRY FOR ANY CONFUSION.

 

[williamsji]

Even a 435 CCA EFB 51R will still be superior to the AGM and the OEM 51R, for reasons already stated. That said, this came up on my first google search:

https://www.autozone.com/batteries-starting-and-charging/battery/p/duralast-platinum-efb-battery-51r-efb-group-size-51r-500-cca/1070704_0_0

But there are others out there to be had. The only real downside to battery shopping is most chains will not ship them, so it comes down to what is locally stocked in many cases so depending on where you live, they may be more or less difficult to find at your local brick and mortar store.

Also same price EFB and AGM no more no less in Autozone

Thanks - that was the one I posted previously - but someone else posted a screen shot of one from Autozone that only had 435 CCA - and I thought that was the same one I'd posted. I appreciate you helping me realize my error. I have an Autozone nearby so that is a good option for me.

Another reason to buy an Interstate from Costco is that Costco gives you an additional 12 months on their warranty. You get 36 months instead of the normal 24.
