Liter 3.7V 3000mAh 505573 Lipo Battery Rechargeable Lithium Polymer ion Battery Pack with JST 2.0mm Connector

This was a successful replacement for the original battery in a Riki Skinny mirror. It's ticklish work, requiring some work, but it functioned beautifully! IF you can solder and have the stuff, do it. If not, strip and wrap the wires from circuit board to battery and tape them up tightly. Note: I only stripped one wire at a time on the battery and completed that connection before taking the second wire out of the tiny (incompatible) plug -- to avoid risk of shorting the new battery.

I ordered this battery after my Abode Keypad 2 stopped holding a charge two years after purchase. I researched it on Reddit, where someone bought this type of battery from an eBay seller, however I prefer to purchase things like this through Amazon if I can and found it here, and as the Amazon customer "Mrtz" said in their review, it works with the Abode Keypad 2, however they didn't realize you don't have to snip the wires and splice on the connector from the old battery. Since the metal parts in the plastic connectors are the same size, all you need to do is carefully use a micro screwdriver to gently lift the plastic legs on the connectors a little bit (they hold the metal ends on the wires in place inside the connector) and then slide the out. Then you can swap the plastic connectors, no wire splicing needed! I actually found prying the darn Keypad 2 case apart more difficult due to the hidden plastic clips holding the two halves of the case together. One more tip - I didn't realize that it was possible to totally disable the motion detection capability on the keypad to save on battery life by a long press 4 + 6 on the keypad! I had set the Keypad motion sensor to "ignore" in the Abode app, but that apparently doesn't actually disable it, so the battery will drain fast even though the system isn't using the motion sensor. You have to disable it with the keypad itself. Hopefully I'll get more than two years out of this replacement battery.

Replaced a faulty battery in a lighted beauty mirror (Riki Mirror). Just snip off the connector, strip the plastic off the ends of the wires, connect red to red and black to black, wrap in electrical tape, secure with tape, put the cover back on and you are back in business.

My AnyKit otoscope https://www.amazon.com/gp/product/B081DF1DGZ refused to turn on recently and after disassembling it saw the internal battery had failed (the PCB on the battery, not the cell). The Liter 505573 was a direct replacement battery and it had the right connector as well. Plugged it in and the Anykit otoscope is working great.

The size for replacement internal battery was correct, but the connectors were different so had to splice in the old connectors. Saved the keypad from going to recycling.

The male connector's traditional positive terminal is showing negative. The battery's red and black wires had the correct polarity; but, they are connected incorrectly into the 2-in JST PH male connector.The incorrect wiring shorted out my equipment.
