Maintenance free means just what the names implies. You will not need to add water to this battery ever.
to help it speed it upAll car batteries work with a weak acid in them. Many modern batteris are 'low maintenance', so they don't need looking at. Most older car batteries needed topping-up with pure water (not tap water) as evaporation occured.
You will not get all the features free, but you may get some of its features in free of costs. Initially you get the website free to handle, but later you will charge for its maintenance service.
Some are rechargeable batteries and some aren't. Check the label.
Vehicle maintenance software can't be downloaded for free, because this is very expensive software that is also used in many car repair centres. For some maintenance software, there will be a short demo available for customers to give an idea of what the software has to offer, but full versions aren't free of charge.
CMMS can help you find reputable predictive maintenance software that is right for you. They will show you different packages and give you free quotes as well as tell you what you need to be familiar with.
A chemical reaction generates free electrons which build up a potential called a voltage and then the electrons can be drawn from the battery as a current to supply a load like a flashlight light bulb or your cell phone. Some batteries can be recharged to provide additional free electrons in conjunction with the chemical reaction.
You can't "recycle" a battery but there are rechargeable batteries. Rechargeable batteries range in size anywhere from AAA to car batteries.
"Gluten" is a protean found in wheat flours. Some people with 'celiac disease' are allergic to gluten.Foods sold for celiacs are labeled as "Gluten Free", you must assume that all processed foods without this label MAY contain gluten.
Some batteries do contain mercury but only specialised ones.

Are you considering the purchase of some button batteries for an electronic item that you have? These are batteries that are exceptionally small and used for smaller electronics. Some of these batteries are harder to find, and you might want to go online and use the web to look for retailers that sell the batteries you are searching for.
Automotive batteries generally have a liquid electrolyte in them. The electrolyte is usually a solution of sulfuric acid and water. Occasionally, under adverse conditions some of the water will evaporate. Some auto batteries have caps, plugs, or covers on the top of the battery allowing you to add water if the liquid level drops. However some [if not most today] auto batteries [sometimes called "Maintence Free"] do not have any way to access the cells to add water. There is also a new "dry cell" type of battery that does not have liquid in it.
