Johnson 9.9 Service Manual

Battery Basics Guide to Batteries. If you have done any research on how batteries work or what you should look for when selecting a battery, youre probably buried in information, some of which is conflicting. At Battery. Stuff, we aim to clear that up a bit. Youve most likely heard the term KISS Keep It Simple, Stupid. Im going to attempt to explain how lead acid batteries work and what they need, without burying you with a bunch of needless technical data. I have found that battery data will vary somewhat from manufacturer to manufacturer, so I will do my best to boil that data down. This means I may generalize a bit, while staying true to purpose. The lead acid battery has been used commercially for over 1. The same chemical principle thats being used to store energy is basically the same as our great grandparents used.

Serial number labels will reference the. If you can grasp the basics, youll have fewer battery problems and will gain greater battery performance, reliability and longevity. I suggest you read the entire tutorial however, I ve indexed all the information for easy reference. The lead acid battery is made up of plates, lead, and lead oxide various other elements are used to change density, hardness, porosity, etc., with a 3. This solution is called electrolyte, which causes a chemical reaction that produces electrons. When you test a battery with a hydrometer, you are measuring the amount of sulfuric acid in the electrolyte. If your reading is low, that means the chemistry that makes electrons is lacking. So where did the sulfur goIts resting on the battery plates so that when you recharge the battery, the sulfur returns to the electrolyte. Safety. Battery types, Deep Cycle and Starting.

After all, you wouldnt want to melt your watchband while youre wearing it The hydrogen gas that batteries make when charging is very explosive. We have seen several instances of batteries blowing up and drenching everything in sulfuric acid. That was no fun, and would have been a good time to use those safety goggles hanging on the wall. Heck, you could even break out your disco outfit. Polyester isnt affected by sulfuric acid, but anything with cotton will be eaten up. If you dont feel the need to make a fashion statement, just wear junk clothesafter all, polyester is still out of style. When doing electrical work on vehicles, its best to disconnect the ground cable. Just remember that youre messing with corrosive acid, explosive gases and hundreds of amps of electrical current. Basically, there are two types of lead acid batteries along with three sub categories. The two main types are starting cranking, and deep cycle marinegolf cart. The starting battery SLI starting lights ignition is designed to deliver quick bursts of energy such as starting engines and therefore has a greater plate count. The plates are thinner and have somewhat different material composition. The deep cycle battery has less instant energy, but greater long term energy delivery. Print Banner Software. Deep cycle batteries have thicker plates and can survive a number of discharge cycles. Starting batteries should not be used for deep cycle applications because the thinner plates are more prone to warping and pitting when discharged. The so called Dual Purpose Battery is a compromise between the two types of batteries, though it is better to be more specific if possible. Wet cell flooded, gel cell, and absorbed glass mat AGM are various versions of the lead acid battery. The wet cell comes in two styles serviceable and maintenance free. Both are filled with electrolyte and are basically the same. I prefer one that I can add water to and check the specific gravity of the electrolyte with a hydrometer. The gel cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium wet cell. However, they store very well and do not tend to sulfate or degrade as easily as wet cell. There is little chance of a hydrogen gas explosion or corrosion when using these batteries they are the safest lead acid batteries you can use. Gel cell and some AGM batteries may require a special charging rate. If you want the best ,most versatile type, consideration should be given to the AGM battery for applications such as Marine, RV, Solar, Audio, Power Sports and Stand By Power just to name a few. If you dont use or operate your equipment daily, AGM batteries will hold their charge better than other types. If you must depend on top notch battery performance, spend the extra money. Gel Cell batteries still are being sold, but AGM batteries are replacing them in most applications. There is a some common confusion regarding AGM batteries because different manufactures call them by different names. Some of the more common names are sealed regulated valve, dry cell, non spillable, and valve regulated lead acid batteries. In most cases, AGM batteries will give greater life span and greater cycle life than a wet cell battery. SPECIAL NOTE Its common for individuals to use the term gel cell as a generic term when referring to sealed, maintenance free batteries, much like one would use Kleenex when referring to facial tissue. As a result, be careful when specifying a gel cell battery charger, as many times were told by a customer that they need a charger for a gel cell battery when in fact it isnt a gel cell at all. AGM The Absorbed Glass Matt construction allows the electrolyte to be suspended in close proximity with the plates active material. In theory, this enhances both the discharge and recharge efficiency. Common manufacturer applications include high performance engine starting, power sports, deep cycle, solar and storage battery. The larger AGM batteries we sell are typically good deep cycle batteries and they deliver their best life performance if recharged before allowed to drop below the 5. The Scorpion motorcycle batteries we carry are a nice upgrade from your stock flooded battery, and Odyssey branded batteries are fantastic for holding their static charge over long periods of non use. When deep cycle AGM batteries are discharged to a rate of no less than 6. GEL The gel cell is similar to the AGM style because the electrolyte is suspended, but its different because technically the AGM battery is still considered to be a wet cell.
