Today OEM battery died in my 2016. Bought an Interstate 24F at Costco for $93. Only took twenty minutes to install with the new battery tray.

Replacing a battery is so easy to do, but its amazing how many people delay doing it until their car doesn't start.

My 2002 gen 2 CR-V is ready for a new battery, I am the original owner (99K mi). The existing Kirkland (Costco) battery has a date of 11/08 which I replaced the OEM battery about that time. Having a battery last that long is amazing.

In looking at going to a larger battery it does not appear that the battery hold down will accept the larger 24 R battery using the Odessy tray that is being performed on newer CR-Vs. Just wondering if anyone has changed theirs in the gen 2 CR-V to a large group size without butchering a bunch of parts. I can get an Interstate 51R battery 625CA/500CCA battery at Costco for $76.99. Wonder if it is even worth the effort to do the mods necessary.

With a battery lasting almost 12 years I would replace it with the exact same thing.

I just got the Odyssey hold-down too (Gen 3). It was $6.

You will never see this happen again. In the last five years or so the entire worldwide battery industry has been consolidated to the point that there are only a very few makers now that make them all, and they have uniformly lowered battery quality so they can sell more batteries. The best thing you can do now is just pick any battery with a 3-year free replacement warranty and hope it makes it that long. Likely as not it won't even last that long. Your only other option is a rare premium battery, which will run $300 and up, and may still not last longer. My last two 51Rs lasted 18 and 15 months, respectively. I now have a 24F AGM, with the 3-year free replacement.

Well the battery died in our 2019 CRV, the tester showed it could only put out 130 amps when it should have been able to do 500...
I'm convinced the previous owner or dealership must have neglected it or let it run down, what kind of battery only lasts a year??

I didn't see any pics or details about putting the Group 24F in a 5th gen so here goes:
It's a snug fit between the brake reservoir and wheel well, so no room for a cover or blanket, but it fits like a glove!
I had to bend the tie down mounting rings outwards as they were flush with the larger battery, but was able to still use the stock tie town and bolts:

The car starts faster, headlights dim less, and I feel much better with twice the reserve capacity of the stock 51R!

Interesting decision. You gave up what I would assume be a 'free' warranty replacement for a self-funded upgrade. I can see the argument both ways.

Did you use the Odyssey battery tray 31521-TK8-A00? Or did you do something else for this Gen 5 installation?

nice.
I was thinking of going with the 2020 h5 battery honda now puts in the crvs

I ordered it but it's not compatible with the gen 5, I ended up using the stock gen 5 plastic tray with the sides cut off to make a flat base for the battery.

nice.

Make sure to measure very carefully, the h5 is wider than the group 24f and mine is already maxing out the available space.

Just curious for those of you with Gen 2 CR-Vs and this battery swap; With the bigger battery in there, how is access to the transmission fluid dipstick? It's not going to keep me from doing the swap, but I'm wondering if I'll have to go through some different contortions to get to the dipstick. I usually drain and add back new fluid to the trans on an annual basis. Thanks.

Great thread!! I need something like this. I already have an AGM group 35 battery.

A question, I notice a few 2nd gens have done this, do I need the odessey tray if I use the group 35 battery? Or just macgyver/cut the 2nd gen OEM crv tray?

 

[Iolaus]

Thanks for that. I was wondering!

Well I decided to use the AGM 35 that I removed from my subaru. The STi is parked over the winter.

I still have the spacer that the AGM battery came with, I was wondering if I can put that spacer on the metal tray, since AGM are suppose to be leak free, and better in the cold climate?

Either way I have all the materials ready.

I used the spacer that came with my size 35 agm. Only suggestion is to connect the battery cables before you fully tighten the securing brackets.
That gives you the wiggle room you might need.

Thanks! Did you use the odyssey tray? With the 2nd gen I'd just have to bend the 2 jhook tabs flat if using the odyssey tray. Seems like I wouldn't have to if I just used that plastic spacer as the "tray".

But Honda has a tray there for a reason.

I used the tray that came with the battery initially to protect the terminals from damage but clipped on to the bottom of the battery. Nothing else was used.

Well I think the little 51r is dead. The temps have been -8C and I fully charged the battery Sunday morning. Today, monday, it didnt start. Multimeter read 7volts.

Well decided to go ahead and stuff the AGM35, had trouble with bending the tabs flat but it will do. It's not flush but its tied down. Add some pics. 2nd pic was to test the spacer. I was planning on just using that. I decided to not use the spacer at all and use the tray.

One of the Jhooks in the kit could not fit in the lower hole so I reused the old one.


Just curious, after changing the battery, it had a hard time starting. Like there was no spark. No cranking just spinning. I had to hold the key in the run position for 7 secs until it eventually started. Now it starts with 1 click. Does the crv have a ecu relearn process that's why it was hard to start?

well after reading through all these pages, I am going with a 24F battery that is sealed. It is 2021, I do not have time for half measures.

Probably more detail here than you want, but fairly comprehensive. Still working fine and no battery shifting after 2 months.
