RVing Tip of the Day

It’s winter and batteries are dying

By Chris Dougherty
Chris Dougherty is a certified RV technician. He wrote this when he was serving as the technical editor at

Through the years I have helped many folks who had destroyed their RV’s batteries. What happened? In each case, they discharged during storage, froze and cracked apart.

Always maintain your batteries. Most RVs have parasitic drains in their electrical systems. These drains come from various electrical components, like carbon monoxide and propane detectors, car stereos, circuit boards, LED lights, relays and so on. Some drains will remain on even if an RV equipped with an OEM battery switch is turned off, to maintain memory in the stereo, and to keep CO and LP detectors operating.

Where this can become an even bigger problem is in freezing weather. Lead acid batteries will freeze if they lose their charge, which can result in their splitting apart. In any case, when they freeze, they are damaged beyond repair.

If you store your RV with the batteries in it, you should make sure that you have the batteries charging. This can be accomplished using shore power, or a solar charging system. The solar charging system should have a high enough charging rate to overcome the parasitic drains on the system.

Regular battery maintenance should continue, including keeping the batteries clean and filled with distilled water.

If, however, you don’t intend to use your unit for a season, it may be better to remove the batteries from the unit and store them in a climate-controlled area on a shelf up off the floor.

Simple custom-sized trash cans
Finding suitably sized trash cans for RVing can be a hassle. Visit the plasticware section of your local discount store and pick up a plastic cereal storage container. The same bag the cashier packs it in fits great for a trash can liner. If it threatens to slide around, use double-stick Velcro tape on the bottom.

Extend life of shore power cordsets
With electricity expert, Mike Sokol 
A great way to extend the life of your shore power cordsets and extension cords is to maintain the contacts with an occasional spray of CAIG DeoxIT D5 contact cleaner. While $18 may seem like a lot of money for a 5 oz. can of spray, you only need a little squirt of it on or in each of your plug contacts, and a can should easily last for an entire RVing season, probably more. It’s also safe for all plastics so you don’t have to worry about melting your connectors with an unknown contact spray. (Been there, done that.) We use CAIG cleaners on our big multi-pin connectors that cost many thousands of dollars each; so if I trust CAIG, then you can trust them too. 

Handy bedside water glass holder
Space tight in the bedroom? No room for a water glass? Your local auto parts store has a great selection of folding cup holders that can screw onto a nearby wall or bulkhead.

Lubricate your RV sewer valves
Nightmare scenario: Your black water tank is full and the drain valve is stuck. That’s a horrible enough thought to send just about any RVer into a cold sweat. But here’s a tip you can use to keep these valves lubricated so this nightmare never happens to you. The lubricant used in the video is available here.

Easy way to clean your showerhead
Can’t get your RV showerhead off to clean it? Fill up a plastic storage bag with white vinegar, “bag” the shower head and hold it in place with a rubber band or other tie. Leave it hanging overnight to dissolve mineral deposits.

“Exercise” your generator
Don’t just exercise the pooch, exercise the generator, too. Fire it up and run it at half-load (or more) for two hours each month.

If you really want to save money on cleaning your RV try Dawn dish soap. Yes Dawn. I could not bring myself to paying those obnoxious prices for RV cleaner. I remembered that if Dawn works on saving oil ravaged animals and areas with oil leaks that need cleaning why not Dawn. I did and wow. Got that camper trailer clean. Especially the bugs. So save yourself money and use Dawn dish soap. It does work.

I’ve seen in many blogs that one should never use WD40 on anything RV because it can get sticky and gummy. But you have an ad for WD40 to keep tank valves from sticking. Confused.

Thanks for writing, Susan. WD-40 is just the brand name, but they make many different products for different applications. Here’s what they say about their Specialist Water Resistant Silicone Lubricant, which is recommended in this video: “WD-40® SPECIALIST® WATER RESISTANT SILICONE LUBRICANT safely lubricates, waterproofs and protects metal and non-metal surfaces, including rubber, plastic and vinyl better than leading competitors. Our silicone spray dries fast and leaves a clear, non-staining film that doesn’t stick or make a mess, so it won’t attract dirt. Effective in a temperature range from -100°F to 500°F, it’s ideal for use on cables, pulleys, guide rails, valves, linkages, hinges, locks and more, and is 50-state VOC compliant.” Looking at their Site Map on their webpage, I see 16 different products listed for different jobs — so one just needs to be careful which product they use. I hope this helps clarify this for you. 😀 —Diane at

My husband and I are newbies and are in the process of buying our 5th wheel as we speak. We just got the mat that sits outside the trailer dropped off today at our house. I am getting into the habit of reading this newsletter first thing in the morning as well. Can not wait to get into our 5th wheel!

Hi, Larry. We’re sorry you didn’t receive your email notification of the newsletter (several people had that problem this time — we’re not sure why). But I just checked the list for email alerts, and you are on it along with your email address. Hopefully this was just a one-time thing. But if you don’t get your email alert, just go to and click on the Current Issue link near the top. The email you receive is not the newsletter, just a reminder notice of a new issue. Sorry for the inconvenience. —Diane at

You can clean the contacts on your shore power cord without buying an $18.00 can of spray. Just pick up a $3.00 wire brush at Home Depot, Lowes, or Walmart, and give them a good brushing. They’ll be as clean as new.

But you can’t clean internal contacts that way. Plus there’s a small amount of lubricant in these contact cleaners that make plugging in and out easier, in addition to reducing future oxidation.

Soapy suds are the last thing to come out of the grey tank and make a great natural lubricant for the valves. My procedure is to open the black back-flush water valve to run water into the black tank first. Then open the black tank valve to empty the tank. Next open the grey tank valve. When it is empty or close to empty (dribbling) close the black tank valve followed by closing the grey tank valve. Lastly shutoff the black back-flush water valve. Works like a charm every time.
