No lo recomiendo. Review: Decent battery for the price, runtime has so far been good in use, lasting around about a day depending on if the LoRa device I'm using it with has the GPS module active or not, polarity wasn't an issue in my case because I was changing the connector anyway but it is always a good idea to check, as I had to discharge it using something else before changing the connector to fit my project I did have to swap the polarity, this is easy to do if you are careful and don't allow the two contacts to short out. For my project the size of the battery was not an issue as I had purchased it prior to 3D printing a case so I could use the sizing as a guide, however again something to check if you're replacing a battery in an existing product. The battery does have an onboard cell protection board under the orange tape where the wires go in, for these types of battery it is important that there is some kind of over discharge protection and this does work as it should, after I did the initial discharge to make it safe to work on to integrate into my project I checked this out with a multimeter. All in all, it's a good value battery and because I have a similar project lined up I'm more than likely going to buy another one ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | EEMB | | Manufacturer | EEMB Co.,Ltd | | Model | LP103454-PCM | | Product Dimensions | 5.6 x 3.45 x 1.06 cm; 40 g | | Batteries | 1 Lithium Polymer batteries required.

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. 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.
