Dead battery in Honda CRV

BKR · 11-24-2011, 09:08 PM

I have a problem with my battery losing its charge as we tow it. I know I'm supposed to pull a fuse, however, I'm a big guy and can't get my body or my trifocals in position that is necessary to do any good. Has anyone tried to take the CD out of the navigation system. I would like to know if this would do any good.

I installed a switch in line with the fuse. The switch is located on the dash so I can turn it on or off for towing. Works great, cost maybe 3 bucks. Dick

No, removing the CD won't help as the system is still powered up. You need to remove the fuse or add a switch as above. I should probably do that to our '05 Ody we tow although I use a BrakeMaster air system rather than one that uses the towels battery to power it.

Just add a Toad Charge

TOAD-CHARGE Dinghy Vehicle Battery Charger/Maintainer

You can get is considerably cheaper elsewhere, and especially if you don't need all the cable and connectors

Hi BKR,
I second SCVJeff's recommendation on the Toad Charge product.

Yup, I use a Toad Charge on my CRV. Never a problem.

I also use a charge system since 2007 and have a problem

I used the disconnect ground from battery method.

We tow an 07 CRV (since it was new) with NAV, never pull a fuse, and have not had the battery go dead, ever. When you get ready to tow, you need to make certain that the AC is off and there is an on screen prompt where you can kill the screen display. While towing we use a separate power supply for the Brake Buddy auxillary brake like Jump-N-Carry 660 Battery Booster - 12 Volt, 1700 Amp#

When we stop for lunch, we run the car to top off the battery, and when stopping for an overnight we run the car for a while after we park. Good luck and safe travels.

The only reason to buy the toad charge would be you have $90 or so bucks you don't need.
If you run wiring back to the toad for power to a toad charge just put a fuse on it and wire it to the toad battery and put the $90 back in your pocket.
You should also install a fuse at on the power line in the tow vehicle.

Thanks, but I prefer to current limit that feed.

If you have a good battery and follow the directions in the manual, you do not need to pull a fuse and do not need a Toad Charge.

The manual obviously makes no mention that there is a reoccurring 10+A draw from the braking system, and the frequency of that compressor cycling is directly related to driving habits, road conditions and terrain. That's one of the reasons this subject keeps coming up. These are not deep cycle batteries but they're being treated as such when they get drained down throughout the day only to take a hard recharge every time the engine is restarted.
