## Description

Replacement LSSP491524AE Battery Replacement for Fitbit Surge Fitness Superwatch FB501

Review: Battery Lasts HALF the Time of the One I'd Replaced! - The title pretty much summarizes my experience. Incredibly unimpressive for something I had high hopes for. Super excited to find this available, I'd purchased this to replace my existing Fitbit Surge battery that was averaging only a couple of days vs. the previous 5-days I'd enjoyed. This kit was really nice, including tools to detach the band and open the watch. One tool broke, but I was able to work around this. Soldering this in was straightforward and this fit in perfectly. Per another reviewer's recommendation, I'd allowed this to completely charge overnight. Unfortunately, I've learned quickly this battery barely exceeds a day before needing recharging, defeating the purpose of my purchase. Unsure if I care to take the time to re-open my Fitbit Surge again to remove this and resolder back in the old one to return this, as it's inconvenient and every time we open these watches designed to not be worked on, we risk issues. I'd attempted communicating with the seller to learn if these were old dying stock or if they had recommendations on improving the life but hadn't heard back, leading me to believe they'll be unlikely to respond if anyone needs to take advantage of the 1-year warranty. Perhaps if your battery is completely dead and unusable would this be a suitable purpose as it does fit nicely, and is, as another reviewer stated "better than nothing". If you get >a day of battery life, keep your Fitbit Surge as it is.
Review: This battery worked for my surge. - The battery worked for me. However, it came with no instructions. There was a good YouTube that walked me through the process. I bought this one because it came with the tools. If you have the correct screwdrivers, the is no need for the tools. Also, I did not see it mentioned anywhere that I would need to solder the battery leads ... just a heads up. Overall, it took me about 30 minutes to complete.
