Are the plastic battery trays necessary? #5328855 01/21/20 03:18 PM

My mom has a 2013 CR-V which is fitted with a wimpy and frankly inadequate group 51R battery.

I'm getting a little tired of constantly having to run out and charge the thing, so the plan is to fit a larger battery. Apparently a group 35 will fit without much difficulty.

However, underneath the battery there's a little removable plastic tray. This is sized to the 51R battery and isn't going to fit a group 35. Is this tray actually necessary or can I just remove it and put the battery on the steel shelf below? I don't want to do anything that could hurt mom's car, but it seems the trays aren't vital, unless I'm missing something. I know that if necessary, I can get a battery tray from an Odyssey Minivan, which drops right in, but that's probably going to require me to mail order the part as I don't think many Honda dealers stock them.

They are resistant to the acid that might come out of the battery. The one on my Cherokee is cracked a bit and the water that comes out of the battery has ate the paint and part of the fender.

Put in a sealed AGM type battery, and you will likely have no leakage, and won't need the tray.

Why is there a need to keep charging the batter, does she not drive often?
Her car may be a good candidate for a battery maintainer. And yes, upgrade that Group 51R to a Group 35.
Or if one will fit, a Group 24F.

She doesn't drive very often, and it's VERY cold where I live, particularly this time of year. There's an aftermarket remote start on the car too, which is probably sucking down a bit of juice.

She also has no garage and has to park outside so that wimpy little battery is really getting walloped.

Apparently, on Canadian market CR-Vs, a group 35 battery is standard, but in USDM they fit the 51R because it's good enough for people who live in California or Texas. It doesn't cut the mustard up here, however. This is apparently a pretty common problem for USDM CR-Vs if you live in this sort of climate.

Nothing wrong with 51R batteries. Don't blame unrelated actions on the batteries condition. I have no problem starting a 454 engine at 35F in my RV with just a jump box, and the battery in that is much smaller than a 51.

My daughter just replaced the OE 51R in her 2015 Civic(build date Oct 2014). I wanted to replace her battery with a Group 35 in the spring but the battery died just prior to Thanksgiving and she lives in PA, - 4 hrs from me so I didn't get the chance.

Put a 24F in there.

Go get a battery tray out of a Odyssey. Around $15 on ebay.

35f? We have 5 months out of the year where the average high is lower than that, and within my memory we've hit -35F a few times.

I was talking about using a jumpbox alone to start a 454 at +35. Guess that's about the same as starting 4 cylinder at -35 with a 51 battery.

Is it even possible for an AGM to leak?



Yeah I might just see if the parts store has anything like that. They probably will. I've heard of people fitting 24s in these too so I might go that route for maximum power.

Walmart have the tray with their "Ship to Store" free shipping if you don't have Amazon Prime.

Whatever you do, make sure they are strapped somewhere.
You don't want a battery that goes down under during a trip and pulling everything with it.
