If you have a PSP, you should definitely check the battery, even if you haven’t used it for a long time.
Many users report problems with their PlayStation Portable on Twitter. The batteries of Sony’s handheld seem to inflate and the case breaks, the battery could leak. You can often read about “exploding batteries”, but there has never been a bang with fire and smoke, the batteries apparently simply swell. Nevertheless, there is a risk of fire in the event of a malfunction.
Incidentally, this can happen with accumulators and batteries in general over time. It is therefore advisable to regularly check your own stock of electricity donors.
Please make sure to properly dispose of the lithium-ion battery. Broken batteries don’t just belong in the household waste. According to the Federal Environment Agency, you can return old batteries and accumulators wherever they are sold, the shops are legally obliged to do so. For more information, visit the website of the Federal Environment Agency.
So if you use a PSP at home or just have it in your closet, take a look for safety. The affected models seem to be the first PSP 1000 and later slim versions, but you should still have a look at your PSP.
