Between 3,000 and 5,000 recharges can be made out of lithium batteries. Accordingly, they may last up to twenty years if recharged often. AGM batteries can also last six years if maintained properly. Lead-acid batteries can last up to 6 years if maintained properly. Since gel batteries have their own charging profiles, they take ten to twenty years to reach their full potential.
The average time to charge a deep cycle battery:
- Lithium charging time: 2 to 3 hours
- Lead- charging time: 8 to 16 hours
- Gel charging time: 5 to 10 hours
- AGM charging time: 5 hours
Charge with solar power
Any deep cycle battery can be recharged by solar panels. Charging of the solar panel and batteries is controlled by the solar charge controller. In addition, you can use an energy monitor with your solar monitor to see how much power your panels are producing.
Installation of Deep Cycle Battery:
No matter whether you use a lead-acid battery, gel battery, or AGM battery, the installation process is the same. Batteries that are 12 Volts or 6 Volts must be wired in series or parallel. You should connect the positive terminal to the positive wire on your coach and the negative terminal to the negative wire.
Normally, lithium batteries are charged via a converter charger built specifically for them: positive to positive, negative to negative, or ground. Lithium batteries should work with the converter on your rig. The voltage required by standard converters prevents lithium batteries from being charged to 100%.
