  • Caution: Check the connector polarity
Just getting started with this battery, so not much to say yet, except that I connected the battery to the DF Robot Solar Power Manager Micro, and tried to charge it using USB power, but then discovered that the battery connector has opposite polarity from the Solar Power Manager Micro receptacle, so I had to pull the battery connector pins from the JST connector and swap them. Fortunately, the Solar Power Manager Micro module has reverse polarity protection. Use caution and double-check the polarity connection when using this, or any similar battery. ... show more

  • Just the right size for making a old PSP battery new!
If you looking to buy a new PSP battery online, its most likely fake as all the 1800mAh ones I've seen are just 600mAh & don't hold a charge very long & say they will go for 7hr on the PSP's Battery Info but you'll be lucky to get one that works for 2hr at most. As I was looking to rebuild my old battery using a new battery cell & trying to go by Size for a PSP 1000. Luckily this battery was just what I was looking for, fits right in the old battery shell & has room for the PCB & wires too. Once all wired up & tested to be working good no problems & give 6Hr & 40M or so battery life. ... show more

  • Received 2 different types and sizes of batteries
I ordered 4 1225mAh batteries and received 3 labeled as 2000 like the one pictured and then one that’s a totally different size but is actually labeled as 1225. Can’t say I really trust either of those ratings to be correct but the battery life seems to be okay so take that as you will.

  • I Really can't find anything else like it...
Only con was the actual dimensions were 50mm x 29mm x 9mm. That being said after looking at dozens of online battery stores, amazon, ebay and then some. This is the smallest battery I could find with the highest mah. I used it to modify my Sennheiser MM450-X because its 370mah battery was shot and wanted to go all out and increase its battery life without sacrificing to much compactness. Rip old battery out, solder on to + and - terminals where battery was on PCB charger, drill some holes, electrical tape, and 3D print an external battery case and voila! This thing has been running for 36+ hours straight on max volume with intermittent activation of active noise canceling. ... show more

  • backwards connector and is oversized
The connector was wired backwards for my application. Always check new batteries to old ones that work (or worked) and double check before plugging in to project! Battery is a few millimeters oversized than advertised. Still a good deal, just a few headaches...

  • The battery is 29mm wide not the 27mm quoted in the text.
The battery is 29mm wide not the 27mm quoted in the text. This made it too large to replace an existing battery that had died. I needed it to be at the largest 27mm.

  • If something looks too good to be true...
When I discovered this battery on Amazon, my initial impression was disbelief. How could a battery that was so lightweight and of such compact physical dimensions possibly have the advertised output? But instead of trusting my intuition, I was foolishly optimistic and purchased the battery to be used as a backup for a compact drone. The battery did charge correctly and the output voltage was correct. Unfortunately, when placed under any sufficient load, the voltage dropped excessively and the drone shut down. In hindsight, I should have known better. ... show more
