Do I Need to Fully Charge My Robot Vacuum Before First Use?

Tapo Device use lithium batteries, eliminating concerns about memory effect commonly associated with traditional nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) batteries.

Therefore, there is no need to worry about specific charging and discharging times, and you can use your device at any time.

You may have encountered charging reminders elsewhere, suggesting extended initial charging periods or complete discharge before recharging.

This advice is rooted in the memory effect of traditional NiCd or NiMH batteries, where incomplete charge and discharge cycles lead to reduced usable capacity over time.

These batteries seem to "remember" previous charging and discharging patterns, providing only the capacity utilized in previous cycles. Regular full charge and discharge cycles are recommended to break this memory effect and allow the battery to utilize its full capacity.

Modern battery technologies, such as lithium-ion (Li-ion) batteries, are largely immune to memory effect issues.

This is primarily due to their different chemical structure and operational principles. The working principle of lithium-ion batteries involves the movement of lithium ions between positive and negative electrodes, without the involvement of crystalline structure changes. In contrast, the active materials in nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries may experience crystallization and dissolution during charge and discharge processes, a key factor in memory effect. The chemical reactions of lithium-ion batteries do not involve such crystalline changes, making memory effect less likely in everyday use.
