There are significantly higher upfront costs that do vary between brands. Many reviews of the agm battery do warn the buyer than you get what you pay for. Finding a truly higher quality battery seems to be worth the cost, but only when properly maintained. The most costly battery to purchase is the lithium battery. The upfront costs for a quality battery can start at three times the cost of the flooded battery. The costs for batteries really does depend on the brand and the habits of the user versus the manufacturers instruction Considering brand, chemistry, warranty, and user habits make calculating lifetime costs very difficult. If you pay only.00 for a battery that only lasts for one season compared to a 200.00 battery that lasts 6-8 years you may well want to put out the 200.00.

An economically priced battery used for the wrong purpose and/or not properly maintained, will create more golding expense in the long run. The flooded battery is the least expensive of all the battery options available. However, they do require more maintenance than other batteries. If you want more fun than maintenance, it would be wise to invest in a more advanced technology. For many owners, the gel parvana's technology has proven to be overrated. Others are very pleased. Priced between the flooded battery and the agm battery, there are reports that the concerns about vibration and the lower cycle rates, and the environmental concerns surrounding the silica used to gel the electrolyte make this a less appealing alternative. It is safer with less maintenance than the flooded battery, so it still may be worth the cost. The agm battery seems to be at the top of the list for traditional technology. The glass mat resists vibration and makes the battery more spill proof than the flooded and gel chemistries. It is longer lasting than both.
While charging, pressure valves allow oxygen produced on the positive plate to golf migrate to the negative plate and recombine with hydrogen and produce water. These batteries have a lower internal resistance that allows for greater starting power and charge reception. Again, with no gasses escaping, less maintenance is needed. Lithium Technology batteries are lighter than the lead-acid counterparts. These batteries can be discharged 800 times to 100 and recharge in about an hour. They work beautifully for electric boats and other high-performance applications. The costs involved with marine batteries varies by type, brand and application.
These batteries require periodic refilling with distilled water in addition to other maintenance needs. Gel Batteries are named from the combination of sulfuric acid, fumed silica, pure water, and phosphoric acid making up the electrolyte. The gel is viscous and prevents leaks. These are recombinant (resulting from new combinations) from the small amount of gasses that combine to make water and prevent drying out due to charging. The charging system must be carefully regulated to prevent high voltage overcharging. No vents mean no gasses escaping, which means less maintenance. Agm batteries or Absorbed Glass Mat batteries feature glass mat separators saturated with acid between the batterys positive and negative plates.
The electrolyte is lead and lead oxide, which traditionally was a 35 sulfuric acid and 65 water solution. The electrolyte causes a chemical reaction that produces electrons. Over time pulling a load, the sulfur rests on the battery plates reducing the amount of sulfuric acid in the electrolyte. When the electrolyte loses sulfuric acid, electrons stop being made; so, there is less power created. When the battery is charged, the sulfur returns to the electrolyte, returning power to the battery. Technological advances have provided different mixtures that reduce the amount of sulfuric acid that adheres to the plate thus extending the reserve time (the amount of time the battery can take a load without being charged). The Elements of a good Marine battery There are three major chemistries to consider when searching for a battery, flooded batteries, gel batteries, and agm batteries, as well as one newcomer whose technology was developed to power newer amenities created from newer technology, the lithium. Flooded batteries, also called wet batteries, use a reservoir of liquid sulfuric acid to create a pathway between plates to produce the electrolytes. The electrolytes produce hydrogen and oxygen while the battery is being charged which, of course, requires a vented battery box.

A mixture called electrolyte expander, a material made of powered sulfates, is added to the paste to produce negative plates. The composition of the paste can be proprietary and also varies with manufacturer and battery use. Separators are used to prevent short circuits. They are thin sheets of porous insulating material used as spacers between the positive and negative plates. Fine pores allow electrical current to flow between the plates without shorting and burning. Different hypothesis manufacturers are beginning to use different materials for the separators as well.
When pairing a positive and negative plate with the separator, the combination is called an element. There is only one element per cell. The cells are connected with a metal that conducts electricity. The lead terminals or posts are welded. The construction materials used to manufacture the posts have changed over the years as well. Many of the materials that are used have been designed for the purpose of reducing corrosion, big for example, many manufacturers offer stainless steel terminals. The last two steps are to charge the battery and adhere labels.
The Exide xmc-31 battery has a dual terminal design and it is engineered in a way that it can bear heavy vibrations as well as extreme deep cycles. The separator of the absorbed glass mat in this battery is designed with recombination technology, due to which cell dry-out never occurs. The cca of the Exide xmc-31 battery is 925 at 0F and 1110 at 32F. The reserve capacity of this battery is 200 minutes and weighs 78 pounds. Batteries structure The battery is composed of five major parts: the resilient plastic container, positive and negative internal lead plates, plate separators made of porous synthetic material and electrolyte (a solution of sulfuric acid and water).
This mix is better known as battery acid with modern applications adding some other ingredients. Finally, lead terminals are the connection point between the battery and whatever it powers. The first step in the process of constructing a battery is the resilient polypropylene container. The container is divided into six sections also referred to as cells, which are shaped similarly to an ice cube tray. Next are the positive and negative internal grids (plates). These grids are made from lead or an alloy of lead and other metals used for positive and negative plates that will conduct the charge. The construction of the grids varies from manufacturer to manufacturer and battery to battery. After the plates, a paste mixture is applied to the grids. The paste mixture of lead oxide, sulfuric acid, and water is applied to the grids.
