Q: Can Kratax J818 AA batteries be used for blink cameras?
A: The battery is suitable for most people's blink cameras, but when the camera runs frequently (such as an object that is constantly moving), the current consumption is too large, it may affect the usage time.
Q: Lithium-ion batteries and disposable batteries, which lasts longer in the flashlight?
A: The disposable battery has a long working time, but the lithium-ion battery can be repeatedly charged and discharged, the overall use time is longer, and the cost performance is higher.
The disposable battery can maintain high brightness due to the relatively high voltage during early operation. Then as the voltage decreases, the brightness will become lower and lower until the user replaces the battery.
The Lithium-ion battery voltage is constant, so the flashlight can maintain the highest brightness in the setting until the battery stops outputting, so the working time of a single lithium-ion battery will be about half less than that of a disposable battery.
Q: Why does it feel like a disposable battery discharges more power than a Li-ion battery?
A: Because the disposable battery does not need to be charged, it can use up all the power. Lithium-ion batteries require a secondary charge of the battery, so some of the power needs to be retained to maintain the battery's activity, So it will feel like the disposable battery releases more power.
