In the solar industry two battery chemistries work well for our purposes.
Lead calcium battery for solar.
The battery is a sealed lead acid sla and uses agm absorbent glass mat technology.
Lead calcium batteries are a form of lead acid batteries having an alloy of lead and calcium.
In addition it reduces the overcharging gassing and water usage.
Lead crystal batteries first came on the scene in 2009 so they are a relatively new deep cycle battery option.
Calcium based batteries promise to reach a high energy density at low manufacturing costs.
Mighty max battery 12v 100ah sla agm battery is worth an investment for your solar power systems.
We ve written an in depth comparison of lead acid vs.
Other than that less water usage longer life because of less hydrogen oxygen generation there is nothing that i know of that would give you 4 5x longer battery life.
In the early 1970s lead calcium batteries were installed as maintenance free batteries because less hydrogen gas resulted in the electrolyte lasting much longer.
In general calcium was added to lead acid batteries to reduce gasing used less distilled water.
Renogy s gel battery is designed for solar energy storage applications.
Batteries come in many shapes and sizes.
It s suitable for daily use and or to provide backup power to small or large solar setups.
This lab scale technology has the potential for replacing lithium ion technology in future energy storage.
The technology found in lead crystal batteries uses an advanced patented formula a type of composite sio2 electrolyte developed to completely replace traditional acid battery solutions.
What this means is that you don t have to worry about regular maintenance of the battery.
These batteries have a longer service life and easy maintenance.
Again you can install the battery in any position except upside down.
12v lead acid car starter battery not recommended for solar charging for solar charging applications you instead want a deep cycle battery similar to those used for marine vessels or golf carts a typical car battery will not work.
The grid of the battery contains lead calcium alloy.
Lithium batteries previously on this blog but here are the cliff s notes.
Lithium is the premium option with a longer lifespan and fewer maintenance requirements.
Valve regulated lead calcium batteries for standby applications capacities from 100 to 600 ampere hours 8 hours to 1 75 vpc 343 to 2060 watts per cell 15 mins to 1 67 vpc liberty series 1000 valve regulated lead acid vrla batteries are engineered to provide performance reliability and consistency over the life of the product.
Lead calcium batteries needed to be charged at a higher voltage almost 15 volts and with a special type iu charger.
