The correct choice of battery
If the battery can be placed in airy space, you can choose among technologies: conventional solary-cyclical, hermetically sealed, AGM and GEL batteries.
Therefore, the batteries can be summarized in three large groups, in which the first is less expensive and have a lower life expectancy, in the third group are more expensive and have greater lifetime:
- Ordinary solar cyclic batteries - are up to 600 cycles, which means that the battery lifetime is approx. 4-6 years (including his ordinary cyclic batteries and sealed batteries, which are also suitable for indoor use because they have no release of gas. (More info at: http://amp-solar.com/solarwet/en) -> battery by itself, is emptying approx. 0.2%
- AGM batteries - are from 1000 - 1300 cycle, which means that the battery lifetime is approx. 7-8 years (more info at: http://amp-solar.com/solar-agm/en ) -> battery itself is emptying approx. 0.14%
- GEL batteries - are from 1500 - 1900 cycles, which means that the battery life of approx. 10-11 years (more info at: http://amp-solar.com/solar-gel/en ) -> battery itself is emptying approx. 0.1%
* Note: The number of cycles written in the upper section only applies to the OPTIMUM OPERATION of the battery, which means that the battery is at 20 to 25 ° C, and that the battery is never overcharged or discharged, because this destroys the lifetime of the battery.
