When connecting two RV batteries in parallel, the amp hours of both batteries are added together while keeping the same amount of voltage. Secondly, be sure to charge your batteries in a well-ventilated area, as lead
For those with greater energy needs, you''ll want to consider a larger battery bank (ie – more storage.) This is why some RV''ers instead of having 2 6 volt lead acid batteries as I do have 4, 6, 8 or even more. Example: If I needed more energy, I could have purchased a bank of 4 Duracell''s and I would have a total of 270 AH available.
More than 25% of people now choose lithium-ion over lead-acid batteries. Lithium-ion batteries last 5-8 years, while lead-acid ones last 2-3 years. Lithium-ion batteries need a specific voltage, between 14.5V and 11V. Make sure the charger and regulator work with this range. This prevents damage from overcharging or overdischarging.

I assume you currently have Flooded Lead Acid (FLA) batteries, since you are looking to replace them after 5 years. So let''s look at those first. Since you have two 12-volt batteries, you would have somewhere between 160-240 total amp hours, as they would be connected parallel which is positive to positive, negative to negative.
Each cell in a lead-acid battery is capable of storing 2.1 volts. A 12-volt bat- tery has six cells, while a 6-volt battery has three. The terminology is confusing because a fully charged 12-volt battery produces 12.6 volts and is more than 50 percent discharged at 12 volts. There are two kinds of lead-acid batteries: starting and deep-cycle.
RV camper batteries are usually around 30-50 amp hours, so in the perfect world, it would take less than 9 hours to charge it from empty to full. You should never let a lead-acid battery drain completely though, as it damages the battery and reduces its overall battery capacity in the long run. Lead-acid batteries should be kept above 50%.
Connecting the batteries in parallel ensures that they receive the same amount of voltage, and adding the second battery increases the overall amp-hour capacity of your RV''s battery system. Alternatively, if you wire the batteries in series, the voltage of the batteries adds up, increasing the battery''s output to the RV''s electrical system.
