There are several factors that impacts on the lifespan of solar batteries both negatively and positively. Generally, the following factors may impact negatively on lifespan of solar batteries; Under charging and over discharging of batteries- batteries have limits for maximum charging and discharging, when one of these are violated, this results to lower batteries lifespan. The batteries should have enough solar power to fully charge the batteries. Also, batteries should not be over discharged beyond the allowed limits depending on battery brand. Wrong/poor batteries installation and configuration- when batteries are not properly installed and configured, this may result to faulty and damages on batteries cells hence lesser lifespan. High room temperature – solar batteries should be installed in a well-ventilated area this is to make sure that batteries lifespan is not cut short by higher temperatures and heat buildup. Small/wrong battery cables sizes- batteries should be connected with proper sized battery cables to minimizes loses and overheating of the cables that may results to damages of batteries terminals.
