Enthusiast runs desktop PC off 56 AA batteries — Intel computer lasts less than 5 minutes while playing Minesweeper
- Latest test shows a desktop PC running on 56 AA batteries briefly powers on and boots via an external supply.
- Steam and gaming load prove too demanding, with the system shutting off within about a minute during tests.
- In the final run, even a simple Minesweeper round lasted only 4 minutes 35 seconds before the batteries depleted.
- A later test fed the monitor from AA batteries, but the setup still failed after around two minutes.
- The experiment underscored power supply and wiring limits, with developers adding capacitors and multiple wires to handle spikes.
- The creator noted that using alkaline batteries improved current delivery but remained insufficient for sustained gaming.
- The discussion among readers highlighted Battery Management System concerns for sustaining a 12V load from AA cells.
- Commenters urged exploring use of larger cells like NiMH, AGM, or suitable low-drain laptops components for better results.
- The headline experiment demonstrates how far battery tech has progressed for light computing tasks, even if gaming is impractical.
