January 2, 2025 – A forum user named Glubux has successfully created a household power supply system by recycling over 1,000 discarded laptop batteries, providing electricity for his home for eight years.
Glubux shared details of his project on the “Second Life Storage” forum. This system combines old laptop batteries with solar panels to achieve off-grid power supply, transforming e-waste into sustainable energy.
Located in a shed 50 meters away from Glubux’s residence, the device has been operating stably for eight years since its launch in November 2016, without any battery replacement.
Initially, Glubux used a 1.4-kilowatt solar panel array, a 24-volt 460-ampere-hour old forklift battery, a charge controller, and a 3-kilovolt-ampere inverter to meet some of his electricity needs.
Later, he expanded the scale of the equipment by building a dedicated small house, accumulating about 650 laptop batteries, and classifying them into battery packs with a capacity of about 100 amperes each.
Initially, he also encountered the problem of uneven discharge rates among the battery packs, but Glubux made adjustments by rebalancing the battery packs and adding batteries, ultimately using over one thousand laptop battery cells.
These battery units were assembled onto customized racks, forming a high-performance energy system.
Nowadays, Glubux’s solar panel array has been upgraded to 24 panels, each with a peak power of 440 watts, providing sufficient electricity even during winter.
