View Full Version : Battery tray and hold down clamps

Hello again!

I'm still going at it!

During tonight's session, I realized that the engine battery was completely loose!!! the battery tray is rusted to heck, and I can't even see the hold downs. The site looks like the iron parts of the Titanic shipwreck.

Question : I've seen a few hold down clamps on ebay, but no trays. Is there no other option then to cough up the money for an OEM battery tray? (I've seen Europarts has one...)

Thanks!

pics? Can you find a way to use all rubber bungees? get good ones (USA MAde) china ones are dangerous

typical hold down clamps are pretty simple being just a bar that goes across the top and a length of all-thread

Great ideas!! Thanks!

Too dark at the moment to tale good pictures. But you helped me see outside of the "OEM" box. I'll take the battery out soon (temperature permitting) and see what I can put in place.

My tray had rusted through. I bought a used tray from the guy in Arizona that parts out Sprinters and lists in Classifieds in this forum (parts only). I sanded the rust away and covered it with POR 15. Contact

Bump- I had to replace our main battery last night. I ended up getting an OEM battery from the Freightliner Sprinter dealership here for about $193. It's Mercedes badged, made in Mexico and is not an AGM. It seemed competitively priced when I did a quick online search. Upon replacing it, I noticed that the hold down clamps are missing so I'll probably look to the aftermarket world to see If I can make something work. When I took the old battery out, the tray was quite wet from a recent car wash I presume.

Is there a mod or fix for all of this water that is collected under the battery tray? Is there a way to redirect water that finds its way under the tray, or a way to prevent if from getting there in the first place? The drain holes at the base of the windshield are free of debris and I can't see how water gets under the tray. The tray holds a fair bit of water, considering how many holes are in it. I'd like to prevent it from corroding away since I just saw that Europarts SD wants nearly $150 for a new tray!

My opinion. You will never keep the water out. Wrong. See post #8. :rolleyes: I *still* might consider drilling a couple strategic drain holes.

Earlier some non-OEM options were discussed. My suggestion would be to buy a marine/boat type battery box. See added below. They come in various sizes.

I'd cut the lower part of the box down to tray size and set it on top of the OEM tray remnants. The marine battery boxes come complete with hold down straps which can probably be fit to the situation. A heat gun can be used soften the plastic to slightly change the shape for fit if needed.

Added:
Amazon lists plastic and metal battery trays.

A few examples. Sizes will need to be verified.
A group 49 battery is L 15 x W 6 7/8 x H 7 3/16

https://www.amazon.com/BATTERY-TRAY-STRAP-Group-29/dp/B000Y85T7W ... maybe too small. Cut/modify one end?

Pdxkid,

I used to find the battery tray was always wet on our T1N based MH after I had washed it until I worked out how the water was getting there.

Water flows off the bottom of the windshield, along the top of the scuttle and then, at the Left Hand side (US Drivers side) through a hole into the fender.

It then runs down the inside of the fender and back through into the engine compartment through a large square hole in the inner bodywork directly behind the battery.

I added a duct tape 'flap' to the back of this hole that prevents the water from coming back through and my battery tray has remained dry ever since.

Try lifting the hood and pouring a jug of water down the windshield at the battery end and watch what happens.

Keith.

I have a lot of rust on the front portion of the tray where the corner rim fell apart. I was going to replace it but it is really tight and I'm not even sure if I should messed with it.

Should I just buy a plastic tray and sit it on top of the original one securing it somehow?

Thanks for the battery tray links!!!

I can't advise without seeing it.

I can say:
A plastic tray over the remnants *should* distribute the loads to support a battery.

If you decide to use a tray/insert, be careful to check clearances. The tray will raise the battery. If it raises enough for live parts to contact metal (the closed hood), the battery can short circuit.

Genuine clamps are expensive. $25 each!s
Trays are not at about $95 new. I do have few take offs that are not like Titanic remnants.

Hey Dennis, I found a tray from mopar $113 but can not remove the old one- unless I'm not looking at it right to figure out what to unscrew…it's so rusted.

The good news is that I can charge my battery to 100% whereas in the van I can only charge it up to 84%.

So I put WD40 on the bolts and will let it sit overnight. There was an excellent writeup (https://sprinter-source.com/forum/showthread.php?t=57480) here about how to take the old battery tray out and renew that area. I did not know there was a battery temperature sensor and a tube to drain the water…I learn so much from the service manual and everyone on this forum.

Neither did I. Please provide data on that for future reference.

Interesting. First I've heard of it.

studioRS doesn't mention it in the Write-up or show anything in the pictures.

Please let us know if you actually find a sensor. A quick Google search revealed nothing for Mercedes or Sprinters as to the part existing.

What service manual was that page from? It does look like the typical VA text/format.

I took the battery tray out of my UK spec Sprinter a couple of years ago when I replaced the battery and there most certainly wasn't any temperature sensor fitted to it.

Maybe it's a cold climate or hot climate requirement?

Keith.

PS Why not try searching for it in the wiring diagrams to see what it controls?

Edit to add: Just searched the entire 03MY Service manual and that is the only reference to the Battery Temperature Sensor I can find, no mention in wiring diagrams or Charging System operation.

i was wondering why the only rust on my sprinter was the battery tray.....now i know, i coated it in por 15 but ya might add this duct tape flap now also.

Has any one heat gunned a seized bolt within this area? I can't get the last bolt out in the upper corner of the battery tray…too much rust and nothing to grip the bolt by with my tools.

Going by Bill's pictures it appears that the insert/support tray can be quite thick.

Including a battery strap similar to what is used for boat batteries will help to keep the battery properly in place.

I just checked my tray and without removing the battery I can see rust is coming back and ate through the POR-15.

Another thought for the insert/support tray is to use a scrap plastic deck board as the bottom of the tray, then strap in with ties.
