Semi-long-term storage (battery)
Hello all,
I've got a 2007 Accord EX that I'm not going to be using for about six months. It's garaged, and covered. I plan to take it out for a spin once in a while during this time period, but just a brief (10 min?) ride. Wondering what the recommendations are for helping the battery survive this... Should it be disconnected, or not? I'm thinking that running it (once a month?) will keep things charged enough, or is that wrong? Anything else to worry about? I will check the tire inflation prior to the monthly ride. Thanks for info. -- "Ubuntu" -- an African word, meaning "Slackware is too hard for me".

A smart charge MIGHT work, but my bet is that you'll need a new battery. If not immediately, within 6-8 months. -- - dillon I am not invalid When you wish upon a falling star, your dreams come true.

The battery is a year and a half old (like I said, it's a 2007). What is drawing current when it's off?

Keep-alive on the radio is normally very low. The security system - assuming it has one - will kill the battery in a few weeks to a couple months. In the Toyota Prius the problem is compounded by the undersized 12 volt battery. In the Yahoo! Prius forum, battery minders are widely recommended and seem to work just fine. Mike |

What is > drawing current when it's off? Could you be a little more specific, and > actually try to answer the question? Sure. You listening? "Ignition Off Current Draw" (IOCD) or "Ignition Off Draw" (IOD) is the current drawn by all systems and accessories requiring +12V battery power with ignition off. For example, the typical modern car's security system, clock, stereo, engine management computer all draw current with ignition off. Up to 120 milliamps total, depending on accessories, is typical. Let's say your almost new type 35 battery has a nominal 45 Ah rating. That means it will provide 45 Amps for one hour, 1 Amp for 45 hours, or 0.12 Amp (120 milliamps) for 375 hours, or combinations thereof. So you may expect your almost new battery to provide 375 hours (approximately 16 days) of standby power without auxiliary charging. The takeaways here for a six month pickling are: 1./ you'll need a charger, unless you 2./ install a kill switch that eliminates the IOCD, and if you do, 3./ make sure you have the security code for your factory radio, or 4./ it will become a brick, once the power is removed. |

OK, much better. I appreciate that info. Now, assuming I have the radio code (I do), would it help the battery if I simply disconnected it in between the monthly short drives? If I did that, once the vehicle is returned to regular driving, and the battery gets a good charging from that, could I expect the battery to be none-the-worse for the experience? -- "Ubuntu" -- an African word, meaning "Slackware is too hard for me".

Yes, using a kill switch, that's been my experience following the annual November-March picking of my sportscar, for the past 20+ years. |

Thanks for info. following your usual advice, we should all respond along the lines of "get rid of that junk, buy a new car". but seriously, you have two options on the battery: 1. disconnect. but that's not so good - they still discharge, albeit slower. 2. run a smart charger on it. that'll keep it perfect. make sure the hood stays open though so any battery vapor dissipates. running a car for 10 mins once a month is worse than just leaving it. motors don't reach full working temp for about 20 mins. if you're going to start it infrequently, run it until it's good and hot to burn out all the acids, condensation, gunky fuel, etc. |

OK, I will probably just disconnect it. Don't have a charger and don't want to buy one. Also don't want to leave the hood open. > running a car for 10 mins once a month is worse than just leaving it. > motors don't reach full working temp for about 20 mins. if you're going > to start it infrequently, run it until it's good and hot to burn out all > the acids, condensation, gunky fuel, etc. OK, I'll run it 20-30 minutes then.

Tires are much more expensive than a new battery. Probably every 3-4 weeks. Don't have any stands, and it could use a new set of tires anyway, so not going to worry about that aspect. > pull the fuse for the security system.
