9-V Block Single Use Batteries
9V or 9 volt batteries are easily recognized by their rectangular shape and top positioned, polarized connectors. They are an extremely common battery among devices like walkie-talkies or smoke detectors. This is due to their incredibly long life span before replacement is needed.Are these lithium or alkaline batteries?
9V batteries come in both lithium and alkaline varieties. The difference between the two boils down to a structural level.
Lithium batteries use lithium compounds as their anode component. They are usually more compact in size and higher volts.
Alkaline batteries use manganese dioxide and zinc to produce their power. Alkaline Manganese Dioxide is the long hand name for an alkaline battery. They are able to work flawlessly at low temperatures and have expansive shelf lives. A 9V is more likely to be an alkaline battery than any other type.How do you dispose of them?
Most fabrication companies discontinued the use of mercury in their products more than 15 years ago. Because of this fact, exhausted batteries can be treated like any other type of waste and thrown away in a trash bin. If you are unsure, look at the packaging to see if your product contains mercury.
The most ideal method of disposal is recycling. Many towns or cities will have designated drop off locations where you can take your dead products so that they can be re-purposed or reused.How should batteries be stored?
Good practice is to store your 9V battery in a dry, room temperature space. Many people think that storing them in a freezer helps to prolong their life. However, this actually decreases a 9V's staying power and has negative implications for its overall performance.Is a device ruined when a battery has leaked on it?
It is not uncommon for a battery to leak on a device, especially if it was not removed before an extended time in storage. The residue can look white, off white, or slightly brown in appearance. It can look like a hard or powdery mineral deposit as well. The item is not ruined if it has leakage on it. To clean it you:
- Find a well-ventilated area and put on a pair of gloves and protective glasses.
- Mix together equal parts vinegar or lemon juice with water or one tablespoon of boric acid with one gallon of water.
- Submerge a toothbrush or Q-tip in the mixture.
- Scrub clean the electrical components in the product that has leakage on it.
- Let the electrical components completely dry before placing new batteries into it.
Unless a battery is specifically designed and constructed as a rechargeable unit, you should never attempt to recharge it. This can damage the structure of the battery, it can cause leakage, and in turn it can cause injury. These batteries are intended for a one time use until they are exhausted.
