Recommendations for Starting Battery


 

Having a very meaningful discussion on Facebook regarding Starter Batteries, and I am sure some of those folks ask with regard to Subaru Motors and Starting Motors.? Sure, Subie is Higher Compression, takes a little more Umph.? But slick if all OK.? Next, folks candidly asking, is a Group 41 battery better than a T5 from Walmart?? I honestly think even Warren Chapman would like to get in on this discussion for overall performance.? Only a $50 difference cheaper, but they sure fit nicer or so I have been told.? From what I know, batteries wear out over time, like 7 or 8 years...just the way it goes.

I notice that MightyMax's AGM motorcycle batteries likely have more than enough CCA to start our 2.2L engines.? ?Maybe I can put one of these in back?for starting.

Or.... I just noticed that we can now purchase a 50AH LiFeP04 for appx $100?that supports 10kW (200A) surges for $50 that's?amazingly small too.? ?Perhaps one such battery would be better than haivng?separate house & start batteres, and it will be warmed up so taht?it can charge if it's in the engine compartment.? ? ??

My condenser is on the roof and has two fans.? One of my evaporator/heater units is on the ceiling next to the right d. Pillar..? ? The other is inside my dashboard.? ?Each evaporator /heater unit supposedly has a capacity of 1.5 T (18k) has its own TXV. It works ok, but is a bit under sized.? I also have separate heater valves for the front and rear boxes.

I used the standard Subaru compressor.

What else did you do to increase the capacity of the AC to 32K?

There's enough space for the battery and AC lines.?

My AC lines run through there as well since my 32k BTU replacement headbanger AC is fed through the right side to disentangle them from the cabinet.?

You run your heater lines there too?? Where do they go?/what do they feed?

Thanks.? ?I probably will need to put mine on the left side because my condenser, rear refrigerant, and? heater lines run through my d pillar on the right side.? ?In short, my right d pillar is already pretty crowded.

I placed the subie intake box on the left side and need to see how much space remains? Maybe only 8x8x8.? ?That's appx the same size as my agm.?

I still wonder about mounting below the floor, or above the trans axle, with access via the underside.? ?

I have a 92 ej22 and the original VW starter in my 81 westy and used to have a 50 AH agm behind the passenger seat.? ?Didn't spin very fast.? ?I moved? the battery to under the back seat (and now store shoes where it used to live).? The original starter now spins with vigor thanks to the shorter electrical connections.? ?Maybe a direct ground wire from the original spot would provide the same effect?

We really want to create more storage.? Beyond exploiting space between the inside and outside walls, I'm now thinking of moving the battery to the underside.? ?The question is where.? ?Thoughts?

where on facebook is this battery discussion?


 

Uh...not sure Eric.? I am so on many of these discussions; it is the only way to preserve the beast, every little clue you can get.? I don't even want to say..Maybe Vanagon Cafe, maybe Vanagon Owners Group.? I think both of those are good groups.? You will see a lot of cross posters like me.? No, they are not going for fame, they want success for all of us, that is their desire.? My take?? Go for Group 41 if you can find it; go for T5 at Walmart if you can't.

Morning All.
This thread is veering off into general repairs (battery & a/c) which are thoroughly documented in other vanagon related forums.? Let's try to keep it subaru conversion related.
Thanks very much,
Brent


 

Sorry


 

Yeah, I was wondering about topic wonder too BUT the?ac compressor is a valid Vanagon engine conversion issue because:

1) some direct subaru fit compressors are no longer made?
2) the pipe connections are specific whereas?the FS10 has generic connections so use in an alternate vehicle easily with generic fittings
3) the?volume of a vanagon is more than?2x the volume and exponential sun-exposed body surface area of a subaru wagon so the subaru compressor at about 6 cubic inches capacity may be better replaced with the FS10's 11 cubic inches.

...I'd still love to see the pictures of the roof mounted condenser etc.? please?email any to AndrewVanis@...
