Insane overnight car battery drain

This has been frustrating me so much i've made an account here to ask for help. I have a 2004 Element EX with only around 151k miles on it. I live where winters get pretty cold, so I feel the cold temperatures might be contributing to my battery drain.

For the past 2 weeks or so my Element has refused to start when I get in at the start of every day. (it only has problems starting the first time, for the rest of the day it'll start up normally before eventually draining/dying overnight.) I turn the key, the engine chugs slower and slower until it stops - the battery is dead. In order to start it i've been using an external battery charger with an engine start feature. Usually the car will start with no problem after hooking it up to the charger, but more recently it's been needing to charge longer and longer before I can start it.

I went to a local auto shop and had my battery and alternator checked - both appeared to be working fine. I don't have much experience with cars or mechanics, my only idea is the cold temperatures could be draining the battery. I'm near my wit's end spending cold mornings hunched over my car battery. Any ideas and suggestions would be greatly appreciated!

We have similar issues up here.... :| I replaced my ineffectual battery with an AGM (Absorbed Glass Mat) battery - in other words - NO LIQUID to freeze/leak out, and one with LOTS of Cold Cranking Amps (CCA). I have yet to have ANY issues with it, and that includes MANY times sitting outside in sub-zero temps for hours on end. Check this thread out for owners who have upgraded their batteries:

Good luck!! :razz: :razz:

I would be looking for a "Parasitic Battery Drain". Since no mention on age of battery I would use a ammeter setting on a multimeter and place in series with the ground cable of battery to check if there is current of more than an 1 amp. If it is drawing more than 1 amp than a would be checking for relays that might be stuck closed. (i.e. not opening ). Make sure that engine is off, key removed from ignition and all interior lights are all OFF before reading. If you do not have the knowledge to use a multimeter in ammeter mode have your mechanic check for you. Do this test after the car battery has been charged. You mentioned that the battery and alternator were checked. I am curious if the alternator is not outputting the current required especially if the heater is turned on with the radio and other accessories and not fully charging the battery. If this battery is over 5 years old I would think of replacing

So I had a similar issue with my ‘04 Element. Local mechanics couldn’t detect the problem. Replacing the battery didn’t help. If I didn’t drive it for 4-5 days, the battery would be so dead, I couldn’t jump start it with my lithium-ion jump starter. I finally took it to a Honda dealership who did an electrical diagnostics test and found that the rear hatch was not latching properly, thus trickle draining the battery. They fixed it and walla, no more problem!

1. Complete your profile. Knowing where you live helps when you comment about your operating conditions.
2. How old is that battery? Self discharge and reluctance to take a recharge are signs of a battery on its last legs, either from old age or from incomplete charging and excessive discharging. If you live in a very cold area, the battery is very likely to never get completely recharged by driving during the winter, and not up to cranking a bone-cold engine. That's what float chargers and block heaters are for.
3. If you need to replace the battery, a group 55/56 will fit with no modification, just discard the plastic shroud and put a piece of 1/4" plywood in the metal tray. I got one last summer at Blain's Farm and Fleet with a better warranty than any of the parts store brands for less money.
4. If you aren't using it already, synthetic oil will reduce the cranking effort during winter. The cost difference will pay for itself if it saves you one jump or hour late getting to work.

Hi, my googling shows a 55/56 1 inch wider than the stock Group 51R. How did you get it in without modification?

If anyone knowa a better battery that will fit in the stock tray please chime in.

The battery tray is sized for the group 56 battery. Honda apparently decided to use the smaller group 51 with a plastic spacer around it at the last minute - probably to cut weight and cost a little bit. BTW, it's getting harder to find a group 56 battery these days.

This started happening to my 04 element last week. I couldn't believe how exactly your description matched my situation.

I actually thought my boyfriend had posted it, as we share the vehicle and he was looking into solutions around the same time you posted this.

I believe I just solved my issue and Im wondering if maybe the case would be the same for you.

Turns out my Progressive Snapshot device was draining my battery SUBSTANTIALLY.

I called and let them know it was an issue and they said they get similar calls all the time.

Not sure if its legit, but there are even law suits in motion against progrssive's snapshot device killing car batteries.

Anyway, I took it out yesterday, and my car started immediately this morning without any chugging!

Do you have a snapshot by chance? Im curious to see if this is the case with your vehicle as well!

Those plug in monitors cause all sorts of problems.

Mostly, check engine light fault codes.

Any vehicle that comes in the shop here, that has anything plugged into the ALDL, it gets removed. Then we have the owner/driver/whoever try it.

Most times we never see them again.

Folks,
I'm also battling the problem of battery draining with my 2003 Element. If car is driven daily it seems to start fine. Sitting 2-3 days, especially if cold, it's reluctant to start. Sit a week or two and I'll probably have to jump start. Battery is less than a year old and shop said it tests good. Alternator putting out proper volatage. The symptoms seem like a parasitic drain, but I've tested for parasitic drain with a multi-meter and can't find anything. Could the ELD have anything to do with this? I do have noticeable headlight dimming/brightening when I slow down or speed up. I'm wondering if the ELD might be allowing an insufficient charge to the battery?

The ELD does that, that is normal operation. It will also throw an ELD code if there is an issue. Does the car crank slow sometimes and fast at other times? What is does your multi meter tell you for a draw? It does not take much to kill a battery.

The only thing I can think of doing is leaving it somewhere for a few days then have someone test the battery before you start it. If it test good then I would point towards the starter motor. If it test bad then you have draw or battery issue. Have you checked the compressor clutch relay? They can stick and kill a battery, but you should of seen that testing the draw on the battery. My brother in law just went through all of this, he replaced the battery and it still had issues starting in the mornings. I replace the starter and all is good. If you where located in Portland oregon I could check it out for you. I know shops are expensive but they have all the tools to figure these things out.
