New life for a PSP battery

The PSP-1000 was Sony's first handheld PlayStation. Its battery is easy to reach behind a door on the back, which makes this one of the friendlier fixes on any old device. But there is a safety point you must not skip. Check the old battery first. Lithium batteries can swell as they age. A swollen battery looks puffy, bulges, or pushes the back door open. If yours is swollen, stop. Do not squeeze it, poke it, or throw it in the bin. A damaged lithium cell can catch fire. Put it somewhere cool away from anything that burns, and take it to a proper battery recycling drop-off. Handle it gently the whole way there. For a healthy swap, just buy a new battery and click it in. Search for a PSP-1000 replacement battery. Be a little careful here: many cheap batteries claim huge numbers that they do not really deliver. A trusted brand at an honest rating beats a no-name pack with a giant number printed on it. Genuine Sony packs are long out of production, so you are choosing among aftermarket ones either way. The PSP-1000 also uses Memory Stick Pro Duo cards for games and saves, and those are old and pricey today. You do not have to hunt them down. A cheap adapter lets a common microSD card act like a Memory Stick. Search for a Memory Stick Pro Duo adapter for microSD. Pick one card and format it in the PSP so it reads cleanly. Two quick wins in one sitting: a fresh battery and a microSD adapter turn a tired PSP back into something you actually want to carry. Want to confirm which PSP model you are holding? The 1000 is the chunky original. Its spec sheet is in the library.
