There are several disadvantages to gel cell batteries for RV applications. They are leak proof and because of this, they work well for marine applications. Gel cell batteries use battery acid in the form of a gel.

In VRLA batteries, the electrolyte is suspended in either a gel or a fiberglass-mat.

Serviceable with removable caps so you can inspect and perform maintenance or the maintenance free type. Flooded lead acid batteries are the most common type and come in two styles. The two major construction types of deep cycle batteries are flooded lead acid and Valve Regulated Lead Acid. To figure the amp hour rating you can multiply the RC rating by 60 percent. Reserve Capacity rating (RC) is the number of minutes at 80 degrees F that the battery can deliver 25 amps until it drops below 10.5 volts. This same battery can deliver 20 amps for 5 hours 20 Amps X 5 Hours = 100 Amp Hours. In other words a battery that can deliver 5 amps for 20 hours before it is discharged would have a 100 amp hour rating 5 Amps X 20 Hours = 100Amp Hours. The amp hour rating is basically, how many amps the battery can deliver for how many hours before the battery is discharged. These batteries are rated in Amp Hours (AH) and more recently Reserve Capacity (RC). True deep cycle batteries have much thicker plates and are designed to be deeply discharged and recharged repeatedly. Starting batteries and marine batteries should not be used in this application. House batteries need to be deep cycle batteries that are designed to provide a steady amount of current over a long period. The battery or batteries used to supply 12-volts to the RV itself are commonly referred to as house batteries.

Starting batteries should not be used for deep cycle applications. CCA is the number of amps the battery can deliver at 0 degrees F for 30 seconds and not drop below 7.2 volts. Starting batteries are rated in Cold Cranking Amps (CCA). This is what provides the large amount of current in short bursts. Starting batteries have a large number of thin plates to maximize the plate area exposed to the electrolyte. Vehicle starters require large starting currents for short periods. The battery used to start and run the engine is referred to as a chassis battery or a starting battery. Now itвЂ™s very important that you use the right battery for the type of application. The size of the lead plates and the amount of electrolyte determines the amount of charge a battery can store. Lead acid batteries donвЂ™t make electricity they store electricity. Lead acid batteries are made of plates, lead and lead oxide submersed in electrolyte that is 36 percent sulfuric acid and 64 percent water.

Each cell produces approximately 2.1 volts, so a 12-volt battery with six cells in series produces an out put voltage of 12.6 volts. Batteries used in RVs are lead acid batteries, which means they have several cells connected in series. To properly maintain and extend the life of your RV batteries you need to have a basic understanding of what a battery is and how it works.

Testing was done using an HTC Desire running Android 2.2 FroYo.RV Advice What You Need to Know About Your RV Batteries Everything you need to know about RV Batteries This allows you to cancel the shutdown in case you are using the phone, or have the charger in hand.Д«attery reserve works on all versions of Anrdoid. When the battery reaches that level, you will get a notification that the phone will shut down in one minute. Once installed, you can simply run it and specify the percentage of remaining battery level at which your phone should switch off, and thatвЂ™s it. You can purchase it from the Android Market as well as grab it from AppBrain (link provided at the end of the article), or by using the provided QR code. When you need to use it later before you have access to a charger, you can simply switch it back on and use the power reserve.Д«attery reserve used to cost $2 but the price has been slashed down to $0.99. Battery reserve is a tiny app that allows you to set a critical battery level so that when your phoneвЂ™s remaining battery power reaches that level, the phone automatically turns off. Usually when the power runs out, your phone gets switched off and you cannot switch it back on until you plug it into a charger socket. With Battery reserve, you can rest easy as it automatically powers your Android phone off when the battery reaches a certain minimum level. Have you ever been in a situation where your phoneвЂ™s battery ran out while it was in your pocket or bag, and you couldnвЂ™t switch it back on to make a phone call while you were outdoors? It has happened to most of us and can cause a lot of inconvenience on many occasions.
