You can disconnect them from the rectifier and test them with a multimeter. Your first test will be static. The engine is not running. Be sure to disconnect from the rectifier and not just try and pierce the wires with the multimeter end.

They are special wires and insulated a bit more, these are one of the few wires on the motorcycle that carry AC current. Static Test Set multimeter to ohms and test between all the leads in pairs. The reading 0. It should be cold. The fibers that compose the fine glass mat do not absorb and are not affected by the acidic electrolyte.

The plates in an AGM battery may be of any shape. Some are flat, whereas others are bent or rolled. AGM batteries present better self discharging characteristics than conventional batteries within a wide range of temperatures.

As with lead acid batteries, in order to maximize the life of an AGM battery, it is important to follow the manufacturers charging specifications and the use of a voltage regulated charger is recommended. Originally a kind of gel cell was produced in the early s for portable valve tube radio LT supply 2, 4 or 6V by adding silica to the sulfuric acid.

Earlier "wet" cells in glass jars used special valves to allow tilt from vertical to one horizontal direction in to or A modern gel battery also known as a gel cell is a VRLA battery with a gelified electrolyte ; the sulfuric acid is mixed with fumed silica , which makes the resulting mass gel like and immobile.

Unlike a flooded wet cell lead acid battery, these batteries do not need to be kept upright. Gel batteries reduce the electrolyte evaporation, spillage and subsequent corrosion problems common to the wet cell battery, and boast greater resistance to shock and vibration. Chemically they are almost the same as wet non sealed batteries except that the antimony in the lead plates are replaced by calcium , and gas recombination can take place.

Patent 4,, assigned to the German company Accumulatorenfabrik Sonnenschein. Step 1 Open the hood of the vehicle and locate the battery. Step 3 Connect the red, or positive, battery charger cable to the positive battery terminal by squeezing the alligator clip with your hand to open the jaws. Step 4 Connect the black, or negative, battery charger cable to the vehicle's heavy gauge metal frame or engine block as far away from the battery as the cable will allow. Those recommendations are typically printed on the side of the battery.

I would suggest looking further into your battery specification as it will most likely refer to the chemistry elsewhere. The other solution is you can get a charger that works for all three lead acid chemistries assuming you know it is a lead acid battery. If you need further assistance we would suggest reaching out to our tech department.

Photo Credits dead battery image by Katrina Miller from Fotolia. In the meantime development has continued and there are now AGM batteries for the cyclical battery market.

GEL batteries use traditional separators, except that a silicate is added to the acid whereby the acid becomes a gel after initial filling. A fully charged battery will measure Photo courtesy of Flickr. He since moved on to learn a few things about coefficient of drag, G-forces, toe-heel shifting, and how to work the crazy infotainment system in some random weekly driver.

Matt is a member of the Washington Automotive Press Association and is a contributor to various print and online media sources. When this condition arises the battery must be removed and bench-charged, because the voltage required to restore it is higher, which can not be provided by the charging system of the vehicle. Other design improvements included over a conventional battery are strengthened grid supports, sealed terminal connections and stronger retention supports.

These features together with a better efficiency enable this battery to be smaller and lighter than the conventional type. Figure Each plate is wrapped with a glass micro-fibre separator that absorbs, in its pores, the entire liquid electrolyte. Struggling to properly start up your car can lead to inconvenient issues, such as getting to school or work late. By choosing to use a maintenance-free battery, you won't have to struggle anymore. This type of battery has superior cranking and high reserve capacity.

What this means for you is higher cold cranking startup. As you can see, a maintenance-free battery has so many benefits to drivers. Not only do you get rid of the maintenance steps, but you also won't have to deal with any hazardous situations. Youre amazing! The term of maintenance-free battery is only half true. Lead-acid batteries usually consume some of the distilled water during a normal charge-discharge cycle.

According to Car Accident Law :. Good day, just wanna ask if MF battery Fill with distilled water will work again? It what is meant by maintenance free battery a 6 holes ready for refill. Typically we only refill every months. After I experience with a lousy MF battery, I am using back old school car battery. All I need is windows 8 iso image free download microsoft what is meant by maintenance free battery up the wyat water every 6 months and it last me couple years! If you want to make it live longer you need to drill the top with 6 holes find suitable caps and fill each battery cell with distil water. No car battery design would be in the marketplace if it only had a potential to last two years. It is not uncommon for Interstate pop-tops to last a decade. Giving wrong info will not only makes you look stupid. That hydro window will only too up meanh one cell, there is 6 cells in a 12v battery. Dude, the hydrometer that thing you unscrewed to batterh water is only for a single Cell in the battery. So essentially you maontenance only adding water to What is meant by maintenance free battery cell, and not the other 5 cells. Hi Kelvin, Just read your article on MF battery. Maybe due to my fdee. When I was younger conventional batteries were the norm. Hi Jamil, nice to see you here again. I am the budget saving mode, I will still go for conventional car batteries. what is meant by maintenance free battery Today's automobiles are typically equipped with maintenance-free batteries, but that doesn't mean they don't require a bit of tender loving care. Low-maintenance and Maintenance Free Batteries Use of improved materials The appearance of a green-coloured signal means the battery is charged and. Many maintenance free, or sealed, batteries are designed so that is vented during charging collects and is “recombined” back into the battery. Before we tackle the advantages of maintenance-free batteries, you This means you won't have to deal with breakdowns due to this issue. However, the removable caps could leak and possibly cause the battery to explode. An advantage of maintenance-free batteries is that the electrolyte is sealed. What does "maintenance free" mean on your car battery? Does it mean that you have to discard it if it goes dead? No. It simply means that you do not need to. Maintenance-free batteries use calcium alloy of lead instead of an antimony alloy which is able to sustain the water longer without refilling, but certainly not forever! Confused by all the different types of replacement batteries on the use the term Gel Cell when referring to sealed, maintenance-free batteries. The term "maintenance free" is a misnomer as VRLA batteries still require cleaning and regular functional testing. They are widely used in large portable electrical. The case of the maintenance-free battery is made of polypropylene. Electrolyte has a specific gravity of on a fully charged battery, meaning the solution. VRLA batteries are used in the US Nuclear Submarine fleet, due to their power density, elimination of gassing, reduced maintenance, and enhanced safety. Feedback post: New moderator reinstatement and appeal process revisions. Active Oldest Votes. Retrieved The oxygen then travels through the shrinkage cracks in the gel directly to the negative plate which is made from a high surface area pure sponge lead and causes a reaction that combines the oxygen with the hydrogen that is adsorbed on the surface of the sponge lead metal negative plate to create water that is retained in the cell. This chemical reaction removes the requirement to occasionally add water to the cells as there is no evaporation taking place from the sealed enclosure. Its charge goes down after almost every 1 month. Still have questions? Try to ride it at least 3 miles about 5km each time you start it. Retrieved 19 February VRLA batteries are common and found in many applications, such as medical mobility scooters batteries and toy and alarm batteries. Do you see any Damaged Plated or particles in the Electrolyte? Patent 4,, assigned to the German company Accumulatorenfabrik Sonnenschein. Constant voltage charging is the usual, most efficient and fastest charging method for VRLA batteries, although other methods can be used.
