what type of connector does it have?

This battery has a JST connector. 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

Does this work with babysense monitor with battery model LN-704060? Battery has same specs as this product.

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.

Where can i find a battery for my alarm monitor. the specs are sp 634169 2000mah, 3.7 v 150617 7.4wh?

These should work. Make sure you connect the polarity correctly.

Can i buy this with the polarity switched?

Dear Customer, The polarity has already designed by the manufacturer. Please confirm the polarity before installation. We do not recommend our customers making any modifications to the products due to safety concerns and future warranty. It is very dangerous to make any changes to lithium batteries. If you have any additional questions, please don't hesitate to contact us again. Thank you Sincerely, Catherine
