Guidings For RV Battery
Batteries are an essential part of any RV’s power system.When it comes to enjoying your RV lifestyle, the battery you choose will make a big difference. Do you want to know if lithium batteries are better than lead-acid batteries?Is the high price of AGM batteries really worth it?How much battery capacity is enough?today, we are going to discuss the RV batteries.
1 Types of RV batteries
- Lead-Acid Deep Cycle RV Batteries
The most common RV batteries are lead-acid cycle RV batteries,which is made of lead plates submerged in an electrolyte solution that is a combination of sulfuric acid and water. They has two sizes,6 volt and 12 volt. The charge a battery can store is determined by the size of the lead plates and the amount of electrolyte solution. As lead-acid cycle RV batteries can discharge more fully than other lead-acid batteries, if you want to choose lead-acid batteries, be sure you’re using a deep-cycle battery for your RV.
- Lithium-Ion Batteries
batteries are starting to enter the market. Li-Ion batteries are maintenance free, extremely light, and provide far more power storage for a given size and weight, but they are still too costly for most RVers.
- AGM (Absorbent Glass Mat) Batteries
AGM batteries don’t need water because their electrolyte is immersed in fiberglass MATS coated with lead sheets.They can be installed on either side, are more expensive than lead-acid batteries, but last much longer and require no maintenance.
2 Voltage of RV batteries
6-Volt Batteries
6-Volt batteries last longer than 12-Volt , many dry campers prefer them both, and also because because they are relatively inexpensive. For more amp-hours, you can also hook up several in series.
12-Volt Batteries
A 12-volt battery is cheaper than a six-volt one.However, they do not last as long and cannot be charged and discharged as often as before.12-volt batteries are fine for those who normally use for short distance trip, but they are not the best option for long distance trips.
3 Ratings of battery
It is important to know the battery ratings. Ampere-hour (A-H) rating is a method of evaluating battery load time.A-h ratings are determined by multiplying the output current by the time the load is applied (in hours) until the voltage drops to 1.75 volts/battery (considered A discharge).The higher the A-H rating, the greater the power of the battery.
Reserve capacity (RC) is within minutes (80°F) a 100% charged battery can handle a load of 25 amps until it drops to 1.75 volts per battery (10.5 volts for a 12-volt battery, or 5.25 volts for a 6-volt battery).This is more suitable for use when the engine is starting, in which case the engine may be turned off, but the lights and accessories are still on.
The cold cranking amperes (CCA) is the current of AMps that a 100% charged battery can provide for 30 seconds at 7.2 volts (12 volt batteries) at 0°F.The Marine starting ampere (or MCA) is the same as the CCA, only measured at 32°F, which makes it a less difficult test.Crank rating is only important for engine starting batteries.
4 Charging of battery
Discharging batteries deeply (below 50% capacity) shortens their life. Therefore, have sufficient battery capacity is very important, especially if you dry camp. Charge discharged batteries as soon as possible. Use a maximum charging rate of 20% of the amp-hour rating (for example: with 100 A /h battery, use a maximum charge rate of 20 amps). Don’t allow a battery to remain at a low state of charge for an extended period, even overnight. Letting the battery discharge causes it to “sulphated”, losing its ability to receive and retain charge.
Batteries lose power over time, and most RV also have a small parasitic current depletion that will drain the battery in a matter of days or weeks. If left on for long periods non-smart basic power converters damage batteries,such as during storage.That’s because a steady current that overcharges and causes they produced will damage the battery when it is fully charged. For the duration of storage, if your converter are not the complex multi-stage battery maintenance “smart” type, just use a separate portable maintenance charger (don’t use a trickle charger, which can overcharge and damage the battery if left on).
5 Cautions
The acid of lead-acid deep cycle RV batteries are is extremely corrosive. Whenever working with batteries you’d better wear rubber gloves and eye protection. Water and baking soda can neutralize the acid and should be kept on hand when working around batteries.
