    • Reliable and Holds a Strong Charge
Style: 503040 600mAh
This battery works perfectly for my small electronic project. It charges quickly and holds power well during use. The size and connector fit exactly as described, which made installation simple. It has been very consistent so far with no overheating or performance issues. The build quality looks solid for a small rechargeable battery. ... show more

Item: YDL 3.7V 500mAh 502248 Lipo Battery w/ PH2.0mm JST Connector Seller: Wing Deli TL;DR: Double check the measurements of your battery before getting this unit - perhaps the 502248 size batteries are not a real industry standard? So the battery in my sunbeam nightlight gave out and instead of buying a replacement for $25, I decided to replace just the battery. Good for the environment and for the wallet yah? Opened it up and found the battery and figured that like AA batteries, the 502248 designation was an industry standard, so I searched for the cheapest one and took a gamble (I mean the name of the seller implies they are a deli right? Maybe it's just a phonetic spelling and not really an actual deli that happens to sell batteries next to ham, baloney, and cheeses). Unfortunately, as you can see from my pic, the newer battery is a bit longer than the one I am looking to replace. Searching elsewhere (eg, ali you know what website), I not only found them cheaper but also of a slightly different size. So while the seller at least cautions the buyer regarding the connector polarity, they should have also specified the exact size of the battery (not just the dimensions of the connector and package). Lucky for me, I was still able to fit it in my nightlight and it's once again working. Don't have an easy way to measure the capacity of the battery so am hoping it really is 500mAh (i mean it's larger than the original so I'm hoping that it is, even if it's made of inferior materials). FYI, the battery I was replacing is about 5x22x43mm. The one from Wing Deli is about 5x22x60mm. ... show more

    • Perfect for PS3 controller
Fits perfectly in my old ps3 controllers and has double the battery life capacity. Highly recommend getting HUVUL's battery riser from thingiverse so it doesn't sit right on top of the dualshock 3 board.

Used this to replace the battery in a SportDog SDF-100A dog collar. The plug ends did not match, so I had to splice in the old plug on the new battery. Charged right up.

    • Not recommended for a drone
I purchased this as the battery size would have been a good replacement for my Propel Flip 2.0 Drone. I had done a lot of research to match up the battery dimensions and this was even suppose to have the same voltage but higher mAh rating. (stock drone battery was only 750mah) I thought this would give me extended run time. Battery packaging was nice and it fit inside the drone battery case, but I did notice the wire gauge was extremely thin compared to my previous drone battery. Previous battery probably had 16 gauge wires.. these I would guess are closer to 22 gauge. In the end it was an unsuccessful experiment. Even though same voltage requirement and increased capacity the battery would only operate the drone for a few seconds and turn back off, not even able to lift off the ground. ... show more
