my damn battery keeps dying!

[mountainbiker]

Maybe we should do a little non-scientific poll for wannabeH3.

1. What type of battery are you running (e.g., OEM, YT, RT or other) and model if you know it?
2. Any after market electronics that could possibly add to the key-off drain?
3. What is the longest you have had the H3 sit without a dead battery?

I'll go first

1. RT Series 25
2. None (but do have OEM grille lights and SMA roof lights)
3. About 1-2 week before battery is dead (Ford Explorer can sit a month+)

alrity

1. OEM
2. Tons of aftermarket electronics (parasitic drain is around 70 mA at initial key off)
3. 2 weeks +

dont know how this helps

I've been leaving my H3 at the plant while I'm on vacation, it NEVER makes it two weeks without killing the battery. So, I pull the terminals now.

[Planohummer]

wannabe--I'm assuming you have upgraded your alternator(?)

[K9sH3]

Sorry to hear about your battery..

I am more concerned about your back surgery, I hope you continue to improve and get back to all the things you were doing before the surgery.
Get well soon,
K9

a 30amp charge rate for about 4 hours would cure the whole 'battery is fine' discussion. hypothetically, of course.

[wannabeH3]

thanks for the well wishes about my back. if you saw me you would think i never had the surgery. im doing that well.
anyways....
why would i upgrade the alternator? it says in my post above its like a 218 amp alternator... i went to the dealer today after my post op appointment and walked up to the service lady who knows me and asked her to check the battery for me and she had someone do it, they said it was fine, and i said is there anything i can do? and she said ok we will test it till it fails and swap it out. in the end i left with a new battery. i threw it on the charger when i got home and charged it up and we will see how it goes. im sure i wont notice problems now that i am able to drive again... anyways just go back to the dealer and get them to replace it for you!

I have one of these disconects hooked up to the ground on the 442.

It sits for months,turn the knob and it starts right up.

It doesnt hurt that I have a 1000 amp interstate battery

I see a optimum battery in the future for the H3,even though I have no problems since original was replaced in march 06 under warranty.

442, did u get the fused or non-fused one? Why?

K9sH3, send us some of that sun on a Ron Jon's postcard -LOL.

Has anyone tried one of those solar charges? It just seems to much like a gimmick unless maybe you buy a (1) large panel, (2) live in a super sunny area, and (3) get a quality one.

If it could get you maybe 50mA+ (not say the advertised 135mA+), you would think it would be enough to keep your battery topped up against parasitic and normal drains.

On eBay, it seems like there are loads of these VW ones made by ICP. LOL- maybe someone can turn the H3 hood-thingy into a solar panel. Hybrid Hummer here I come.

I have the one without the fuse.
With 15-amp fused bypass?maintains computer settings, clock, radio, etc. while battery is disconnected

With the fused one you probobly would still have a drain.

Solar chargers are good if you have Direct sunlight.

Crappy OEM batteries becoming common? My wife's Jag battery only last 2 years, 3 months with daily usage.
