Great quality and fast shipping — very satisfied Review: Revived our sound machine - We love a sound machine we bought from Brookstone several years ago. As life has it, technology turns over at an alarming rate these days and replacement parts - even something as common as batteries - become unavailable. Our sound machine used a slightly smaller battery with a slightly different plug. But with a little soldering and heat shrink tubing [two wires; one red and one black], this new battery fit perfectly into its designated space. It's a perfect repair for our beloved machine. It's quality of sound for its size plus the types of sounds it creates is our favorite features and we are thrilled to have it working once again [the old battery swelled warping the internal mechanisms]. Sleep is important and with our sound machine we get really high quality sleep. Repairing is always preferable for us over replacing and with this solution we are quite happy. Now, I've got to turn on our machine and go take a nap [yawn]. Don't let the difference in connectors shy you away. With a little ingenuity, you too can repair something. Plus you probably have a friend who could help you out if you cannot do this yourself anyway. Give this a shot. We did and we're glad we did. ## Features - Make Sure Device Polarity Matches with Battery Pack Connector Before Purchase!!!-1.Battery Size; 2.Connector Model; 3.Connector Size; 4.Connector Polarity - This is not universal!!!

The pins are 2mm center-to-center, or 2mm pitch. According to some comments, the polarity was reversed. Double check, and if this is the case, you can use a screwdriver to release the pins from the housing and swap them(there's little plastic tabs you can *gently* lift). Just be careful you don't let them touch when you remove them **Q: Does this work with babysense monitor with battery model LN-704060? Battery has same specs as this product.** A: I think it should work. I used this battery in series with a smaller battery of similar specs and it worked fine. I also used it to replace a battery with matching specs and no problems. i hope this helps. **Q: Where can i find a battery for my alarm monitor. the specs are sp 634169 2000mah, 3.7 v 150617 7.4wh?** A: These should work. Make sure you connect the polarity correctly. **Q: Can i buy this with the polarity switched?** A: Dear Customer, The polarity has already designed by the manufacturer.
