How to Maintain & Recycle Deep-Cycle Batteries


Deep-Cycle battery failures are often not the fault of the batteries themselves. They do need to be attended to every once in a while. However, if they are properly maintained, they should last a very long time. The most important thing to remember about deep-cycle batteries is to buy a high quality one. A good one should last about 5 to 15 years. A low quality battery will only last about half that time.

Deep-cycle battery maintenance should be done very carefully because they contain lead-acid, which can cause serious burns. Wear safety glasses and rubber gloves when working with them. It’s advisable to fill a plastic bottle with baking soda (sodium bicarbonate) and water. This can be used to neutralize any battery acid spills that might occur during the maintenance procedure.

Corrosion is one of the most common nuisances concerning deep-cycle battery maintenance. Apply a coat of sealant that does not harden to all the metal parts of the battery including the terminals, nuts and bolts. Although there are products sold specifically for this purpose, regular petroleum jelly (Vaseline) is a good enough choice. It will not get in the way of the electrical currents. Just spread on a thin layer using your fingers. Once corrosion sets in, it’s hard to stop.

If you find that wires are exposed at any terminal, use heat shrink tubing with adherent lining to seal it, and make sure it’s airtight. You can also use shrink tape that is capable of being submerged in water.

Deep-cycle batteries should be rinsed about twice a year. This helps to cut down on build-up of dust along with acid spills and splatters. This can be done outside in a safe area like a parking lot, driveway or over a floor drain. Rinsing the battery is also a further measure to avoid corrosion and keep stray currents from robbing the battery of energy.

When the battery is ready to be recycled, it’s important to check the laws in your particular state to find out about regulations. In most states, you can simply take it to lead-acid battery retailer or wholesaler. If the location sells those same types of batteries, they must accept it for recycling. They must also accept the same number of that kind of battery that they have sold. You can also take it to an authorized recycling center.

Disposing Batteries Safely

Just about everyone uses batteries for household items. They are used in flashlights, games, phones and many other appliances. This doesn’t account for batteries that are left around, half-charged or dead. Batteries, even dead ones, contain toxic and corrosive chemicals that harm the environment. This renders them as hazardous waste. Throwing batteries in the trash puts the public at risk. Here are a few tips for the safe disposal of batteries.


Suspect batteries should be removed from all devices. Place them inside Ziploc bags or individual sandwich bags that are secured with rubber bands. Use one bag per battery, since if they come in contact with each other, they can produce a weak charge and rupture. Place all the bags inside a larger plastic bag and mark it with a felt pen. Never group several batteries together in one container, like a cardboard box or metal container—they can leak corrosive chemicals and contaminate the container or anything near it.

Disposal Sources

A local City Hall is the best primary contact point. Ask to speak to a person of authority in the Waste Disposal Division. Ask about the next scheduled hazardous waste pick-up for your community. You might be informed of a permanent location that already exists or even a recycling program. Make a note of the address and take them there. If you must wait for a scheduled pick-up, ask about specific instructions for the date, time and place. You might also receive instructions for the manner of disposal and this depends on the community regulations as it pertains to your city or county.

Large hardware stores and improvement centers often have a container for the disposal of batteries. You can call them and ask if they provide this service. If they have no such service, they might direct you to a resource that has this convenience. If they do have special containers for battery disposal, ask about the days and locations for drop-offs and plan your transport on that day.

Car Batteries

Car batteries are extremely dangerous if left out in the open or contained within a household or garage. They contain caustic acid. If the battery case is cracked, the acid can ruin anything it comes in contact with. The fumes of a car battery are also hazardous. Under the right conditions, car batteries can explode. The best place for the disposal of a car battery is the place of purchase, since they deal with Replacing Battery decisions every day. This could be a large department store automotive center, a repair shop or an automotive parts store. Double wrap the battery in plastic and place in your vehicle. Transport it in the trunk or rear cabin area of the car. Place mats or thin wood sheets underneath the battery to guard against any leakage. Roll down the windows for adequate ventilation.
