How to Choose the best group 24 RV battery?

Group 24 RV batteries are a bit complex unlike standard vehicle batteries. For this reason, you need to consider a few factors before picking one. You must be familiar with the guideline in order to get the best results for all your power needs.

Capacity

A 24 RV battery is rated in terms of amperage. Ampere hours is an indicator on the exact amount of current delivered by the battery per hour. Picking a high capacity battery means enough power storage and longer supply. So going for higher is the key. Besides, you need to consider the weight and size. Generally, batteries will higher ampere hours are large in capacity.

However, it’s important to remember that enough room is needed to store your battery. Therefore, calculate your precise daily power requirements in order to find the ideal capacity for your truck. Get a battery with the ability to supply power without getting depleted easily.

Voltage

Voltage represents the electrical force that drives an electric current.  It’s the amount of potential energy an object has at a specific time. Typically, group 24 RV batteries comes with a 12V DC. While these batteries can supply enough power, RV owners in need of extra power can combine 6-V batteries. In addition, its god to remember that solar power kits can effectively operate using 24-V batteries. However, a power inverter is required for current conversion from DC to AC. 

Charging manner

How will you often charge your battery? Here, you need to find on whether you will be using a solar power or generator for your charging purposes. In case you don’t have this, then a shore power or a smart charger is required. Also, a charge controller is necessary to help automatically adjust voltage and current. 

The depth of discharge

This indicates the percentage of a battery’s capacity that has been removed in relation to its total capacity. This helps define the battery’s state of charge. For a lead-acid battery, the depth of discharge is correlated to the cycle life. For instance, an RV battery with 20% depth discharge has a better cycle life unlike one with 80% discharge. Therefore, you need to go for a deep cycle battery with a lower depth of discharge

Vibration Resistance

The over build of your RV battery determines how much it can withstand shocks and vibrations when running. A quality sturdy build means you will spend little in maintenance as the battery rarely gets damaged. . 

Power at low and high temperatures

You also need to find out the ability of the battery to supply steady power whether in low or high temperatures. For instance, if you plan to camp during summer, then a battery with efficient power supply in hot conditions is ideal. 

What is group size for battery?

A group size for battery simply means the ideal battery size that fits the terminal locations and physical dimensions for your vehicle. The size depends on the vehicles model and engine type. Every battery group size has been assigned number and letters by the Battery Council International.

How many types of group battery?

Types of RV Battery

Generally, RV batteries are divided into three groups. They are:

  1. Starting batteries

Starting batteries are measured in terms of cold cranking amps. This type of batteries are designed with a number of thinner plates for maximum surface area exposure to electrolytes. This produces enough energy working is short spurts. For this reason, they are not supposed to be used as alternatives for RV deep cycle battery.

  1. Deep Cycle batteries

Deep cycle batteries are commonly used in recreational vehicles due to their ability to supply constant amount of power for long periods of time. The battery is designed for deep discharging due to its ability to deliver a maximum of 70% of its full capacity. Besides, the battery is made of thick plates with small surface area.

Deep cycle batteries are subdivided into several types below:

a. Flooded Lead Acid Batteries- made of lead-oxide and lead plates, these batteries effectively handle overcharging through the hydrogen venting process. They also deliver large power to ration making them ideal for RVs. 

b. Absorbed Glass Mat- this battery type uses glass mats to hold the electrolyte instead of plates. Its versatile as it works even for rolling motors and boats. It has the ability to handle extreme temperatures and self-discharge slower.

c. Gel- This type is designed with gelled electrolyte which is highly sticky. Gel batteries use solid internal constructions giving them superb durability as compared to others.

3. Dual Purpose

Also known as marine, the battery offers excellent starting power and cycling capacity. The battery can handle starting and cycling but are unlikely to start an engine.

What does group size 24 battery mean?

The group size of a battery is important when it comes to powering your vehicle. This number refers to the BCI group number of the battery. Groups size 24 means the type of batteries designed for general-purpose in appliances such as security systems, stove, light and more. 

The battery is rarely used for starting engine. Instead, it works best as a deep cycle float applications. 24 is the standard number suitable for lightweight vehicles.

What size battery do I need for my motorhome?

The size and type of battery that you choose depends on the application as well as operating conditions. The most popular battery for a motorhome is one 12v or two 6v deep cycle battery and chassis battery for starting engine.

This means the battery supply will comprise of three things:

  •  2 x 120amp batteries 
  • 40amp AC Caravan Battery Charger
  • 2 x 150 watt solar panels on the roof.

The above combination will deliver the ease of powering 12v appliances off the battery system while providing the ability to re-charge the motorhome batteries. It will be a bad idea if you choose a less battery amp capacity in motorhome application since the performance gain will exceed the cost advantage. 

Motorhomes have an engine and therefore will require an engine starting RV battery. The starting battery is similar to one used in cars, tough often with a bigger CCA. You will need bigger batteries with the maximum amp-hour (ah) rating. For instance, a 100-Ah starting battery will give a total of 5 ampere for 20 hours at 26.7 degree Celsius.

For motorhomes with huge demand for power, you have to add 12-V batteries and connect them in parallel. This will increase double the amount of time before they are discharged.

Alternatively, 6V golf-cart batteries can be used by connecting them in a series to yield 12V. This kind of setup can withstand more deep discharges unlike a 12V marine.

Use three-stage chargers

Its also advisable to charge the RV batteries in three stages namely:

  1. The bulk charge- brings the charge to 90%
  2. Abortion- fills the remaining 10%
  3. Float charge- maintains the full charge. 

A 3 charge is quite effective as compared to an integrated charger, particularly if used during storage.

Introduce water after recharges

Water should only be added once the battery is fully charged. In case the electrolyte runs low to a point where the batteries are exposed, first add water before recharging. 

Additional maintenance tips:

Dos:

Clean terminals on regular basis and cover coat them using terminal spray to prevent oxidization.

Recharge the battery fully when preparing it for use.
