EEMB Lithium Polymer battery 3.7V 1800mAh 103448 Lipo Rechargeable Battery Pack with wire JST Connector-confirm device & connector polarity before purchase

Better than the original battery. Revitalised my old trusty receiver and now no need to buy a new one

I needed a replacement for my portable cesk lamp and this fitted the bill, quick delivery too.

Works fine

The battery is good, I used it to upgrade my solar lawn light from 500mah to the battery’s capacity so that I can use the light overnight. The battery size is perfect to be hosted in the original battery box.

Not an exact replacement but able to modify connector to fit and a good price

I installed this battery in a GPS tracker to replace a similar spec unit. For several months, this battery performed as expected: After charging, I could run the tracker for 3-4 hours per day over 4 days before it dropped to 30% (at which point I recharged). Now, 5 monts on, the last few recharges have resulted in the tracker showing 100%, dropping to 20%, in less than 12 hours. The tracker was inactive over those 12 hours. I can only conclude the battery is near, or at, the end of its useful life. Past batteries have lasted at least twice as long with similar duty cycle.

Lasts much longer than the original battery

Bought this as a spare for a drone that uses a 3.7v 1400mAh Lipo battery but after a full charge it won't power the drone. The drone starts it's propellers but when it increases the propellers speed to take off the battery fails to supply enough current and the drone shuts down. That is a typical sign that the battery has far less power (mAh) than is required by the drone. The batteries supplied with the drone are rated at 1400mAh, far less than this battery is supposed to be. So beware this battery is most likely not as good as it is supposed to be and wont be of any use for many drones!
