Storing them in discharged stages for long can degrade their health faster. There can be many factors at play when facing the situation of “why is my solar battery draining so fast,” including weather factors, higher electrical load, poor maintenance, and aging of the battery itself. Why isn’t my solar panel charging my battery?
Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge. Greater the current drawn by the load, faster the battery discharges. Battery discharge during idle status?
It’s best not to fully charge or discharge a solar battery. For lead acid batteries, aim to recharge at around 50% capacity, while for lithium batteries, aim for 35%-40%. Avoid letting the battery charge drop too low as well. For example, if you recharge an AGM battery to 50% and then top it off at 75%, you’re only utilizing 25% of its power.
Any malfunction can bring down the entire charging process. Internal damages due to mishandling, manufacturing flaws, sulfate crystal formations, or simply old age can affect a battery’s acceptance to charge. Parasitic draw and the impact of sulfation are other common solar battery problems. It’s true; a solar battery can require some maintenance.
If a solar battery is not recharged for a significant period or if there is a malfunction in the charge controller, it will experience rapid drainage. Similarly, leaving a battery completely discharged without recharging it for extended periods of time will also result in quick drainage.
Battery Damage: If you frequently let your battery discharge completely (0%) and then charge it to full (100%), it can damage the battery and result in rapid discharge. Recharge your battery when it reaches around 50% (for lead-acid batteries) or around 30% (for lithium-ion batteries) to avoid problems. 3.
