Have QT16 with Onan, think 79'.  See the battery tray area, but don't know how batt sets in it, which way for terminals to be, and how darn thing is supposed to be held in. I was told a Grp 26 battery, have not looked at size in store yet. I want to get one now, but don't know how to mount it. I will need a diff neg cable pretty sure, one in there now is pretty short, maybe I have on wrong ground bolt?? The tray area is not big, so is there another tray that is loose should also be in first?  I have parts book, but don't see the darn tray in any of the pictures shown, or missed seeing or such?  I don't see list for battery type or size either. I DON"T have owner's manual if any of that info is in there.  A picture of batt in a tractor with mounting may help. Not sure if others are same or not w/out the Onan engine?  I have the gas tank (small) behind dash on opposite side of the battery, same main mount.  Straighen me out here!

Measure the inside of the tray both ways.  Then measure the height you can use without interfering with other items.  Go to your Interstate Battery dealer and give him those measurements, the CCA you need/want,  what kind and which way you want the terminals  They will have or can get just what you need.  This is what I did with the Cub 882 I bought  a while back.  Got one smaller than physically than I could use but more CCA (450) than I asked for (400).  Works out great.  I have run nothing but Interstate Batteries for years.

Problem is not much of a tray. Sort of a shelf off the metal frame that also holds the gas tank other side. Darn parts book does not show, or I missed it. I can go out and measure some, not sure which way terms should go, think I can get cables to fit whatever I end up with. Think I want back to center to keep from hood maybe. The plate it sets on is way smaller than a battery would be, and not seeing where to put restraints into the system. Went out to take pix of what I have. First pix is a slot in base, mount point? Second is a tab off of the base frame, mount point?  Can see not very big base, lots of room, battery just hang over all that at ends or am missing another tray for there?  After looking at pix, remembered that slot is for the gas tank strap to pass thru, so not for Batt then I guess.

OK, was told 26 size battery. Found a commercial 26S in TSC for about $59 and had CCA of 550! Seemed like alot for the small size of battery. Book said 26RS was needed for Bolen's. SO, went to Big R and they had about same, same price, but was a 26RS-4 for something like that. R usually means batt terms reversed, so got that one. Fits right into the tray and the lower bulging edge on batt is even the same size as the bumped up edge of the tray. Firs right in/on the tray part. NOW, can anyone tell me which way terminals should be? I think I want them IN to inside of chassis, but could be OUT to the hood edge side I think too w/out problem. What way is normal? I did buy another longer cable for the neg side, it does not reach where I have it bolted now, on the rear cushion mount bolt. SO, where is THAT supposed to be hooked up to on orig??

I held batt lower and hooked up my short ground and engine cranked real good. I sprayed some start fluid down intake ports, (no carb or manifold) to see if it would fire. It went and started for a few seconds, did a couple of times and it was running short time. But, then the fluid caught fire over one end and had to blow all that out before got bigger. SO, stopped that and think with carb back on and right cables this thing is gonna be a runner! Didn't knock or smoke any for the short time it ran, hope that stays that way also.

Pics found on internet show terminals towards the outside, not a single pic I looked at had a top clamp, straps, or even a bungee visible.

If you look at this page from the parts manual that ClassicBolens uploaded it shows the location of the positive and negative cable and the orientation of the battery compared to the dash.  It also shows a hold down clamp across the top of the battery held at each end with a wing nut attached to a u bolt.

OK, have that manual and was looking at it, but not getting it all I guess. Saw the cables and where ends bolted up, about same as I had, just my neg one was too short. SO....guess there is a frame around whole battery, then one HUGE U-bolt around and under the platform and up into frame and wing-nuts hold it?? That's what it looks like now that is pointed out to me. So, I guess could bend rod to make the U-bolt, and have made frames around batterys from angle iron before, add loop to have rod come thru and it is done!  Man, that is gonna be a long process for a simple need. I'll start on that next week now that it is more clear WHAT to do for the mounting. Thanks guy's, glad you saw my postings!

Looks like the part # for the u bolt is 1724895 and this was also used on the HT23's according to the list that LPBolens compiled

 

The part number for the hold down is 1724360  which was used on the 1886, HT-18 and HT-20.

 

Perhaps someone has one of these models with and original clamp or U Bolt they could take a picture of to show you what they look like.

You may want to check out this thread on MTF as I assume your battery hold down would be similar to what this gentleman made for an 1886 - read the whole thread as he shows where he ended up mounting the u bolts at the end http://www.mytractor...surrection.html

Well, made the U-bolt and top part today. I just used 1/4" rod and angle iron for the top. Not much of a place for any U-bolt with selinoid and stuff down there and metal bracing. Pretty much to the outside of tractor, not center of battery, Looks like should work. Gas tank on other side, not going anywhere then. I have to finish the corner rounding and paint the angle iron, but is shown and mounted. I'm moving the terminals to inside as the clamp is on outside and would hit them.

The terminal side of the battery faces towards the gas tank side.  The positive would then be towards the dash board and the negative would then be towards the engine.

 

I'll have to snap a photo of mine to show how the battery U bolt thing works.  The  U bolts goes from under the plate, from the outside, and at an angle, the ends come out on the inside (tank side).  The angle iron rests on the battery's upper (top)  - inside (terminal) - edge of the battery.
