Lithium batteries, however, may be routinely and safely fully depleted. Read this in-depth article to learn more about the state of charge of lead-acid batteries. The whole capacity of a lead-acid battery cannot be discharged.Įven the greatest deep-cycle RV batteries shouldn’t be depleted more than 50% to 60% of their capacity.īeyond that, calamity reigns as sulfates develop, plates fracture, mats flake, and electrolytes freeze.įull battery discharges significantly reduce battery life and may potentially permanently damage a battery.īecause of this, your car’s starting battery often dies a few months after you turned on your headlights all night. You must comprehend the one MAJOR drawback of lead-acid batteries in order to comprehend the attractiveness of lithium batteries for RVs. What’s Up With All the Fuss About Lithium Batteries? However, lithium batteries could soon reduce them to mere footnotes. These upgrades are all beneficial and cost-effective. Changing to 6V batteries with a 12V system rating that are heavy-duty and long-lasting.Buy deep-cycle batteries for long discharges and more useful capacity, which have robust lead plates.Conversion from flooded/wet batteries to sealed/valve-regulated architecture (e.g., AGM).The majority of RVs still come with these 12-volt lead-acid batteries today. Twenty years later, in the 1970s, the market was overtaken by more sophisticated construction types like AGM and gel batteries, but the underlying technology remains unchanging. In essence, this method is still used in batteries today. See our Ultimate Guide to Your RV Batteries for additional details. The plates are kept apart by a separator plate.Ī chemical reaction causes electrons to travel between the two, and presto, electricity. It’s a straightforward process: An aqueous sulfuric acid solution is poured over two plates (the cathode and the anode) (electrolyte). It hasn’t altered all that much since then.

The well-known 12-volt lead-acid battery had become the battery of choice for the automobile and recreational vehicle sectors by the 1950s. Let’s say goodbye to the veteran: the lead-acid battery, before we throw the red carpet for lithium batteries. So, please, take caution!

Whether they are flooded, AGM, gel, or another variety, almost all RV batteries purchased from OEMs and dealers are lead-acid batteries. Please go here to read our comprehensive guide to RV inverters.

To power your bigger appliances, some RVs contain an inverter that converts 12VDC battery power to 120VAC electricity.

Please go here to read our comprehensive guide to RV converters.

Almost all RVs contain a converter that transforms shore power into 12VDC electricity so you may plug in and use minor appliances while charging your battery.Your RV can link the two systems, at least in part. House batteries aboard provide 12VDC electricity. Larger equipment like your air conditioner and microwave operate on 120VAC.īy hooking into shore power at an established campsite or home, you may get 120VAC electricity. Small appliances like fans and lights operate on 12VDC. Otherwise, go on.)Įvery RV has a 12-volt direct current (12VDC) and a 120-volt alternating current (AC) electrical system (12VAC).

Yes, I blatantly plagiarized The Matrix’s blue pill/red pill plot (thanks, Morpheus). I’ll demonstrate exactly how far down the rabbit hole you may go if you continue reading this post and remain in Wonderland. You return to your RV and adopt whatever worldview you want. The narrative comes to an end when you finish reading this article on lithium batteries.
