How Long Will Deep Cycle Battery Last?

It is usually possible to charge lithium batteries 3,000 to 5,000 times before they need to be replaced. As a result, they may last between 3 and 20 years, depending on how often you recharge them. 

AGM batteries are also capable of lasting 6 years if they are properly maintained. Lead-acid batteries, meanwhile, can last up to 6 years if they are maintained properly. Gel batteries last between 10 and 20 years because they have their own charging profile.

Average Deep Cycle Battery Charging Time

  • Lithium charging time: 2 – 3 hours
  • Lead- charging time: 8 – 16 hours
  • Gel charging time: 5 – 10 hours
  • AGM charging time: 5 hours

Solar Charging Option

You can charge any type of deep cycle battery with solar panels. Solar systems usually involve a solar charge controller between the panel and the batteries to regulate the charge. As well as a solar monitor, most installations include an energy monitor, so that you can see how much energy is being generated by your panels and how much remains in your batteries.

Installation of Deep Cycle Battery:

Whether a lead-acid battery, a gel battery, or an AGM battery is installed is the same.

If you have two or more batteries, you will need to wire them in parallel or series, depending on the size of your batteries (12V or 6V). You will need to connect the positive terminal to the positive wire on your coach and the negative terminal to the negative wire on your coach.

In an RV, lithium batteries are attached in the same manner as conventional batteries (positive to positive, negative to negative, or ground), but a converter charger specifically designed for lithium batteries will need to be installed.

Make sure your rig’s converter works with lithium batteries, even if it already has one installed. Because of the voltage required, most standard converters are unable to charge lithium batteries to 100% full, but can charge them to around 80%.
