Lithium-Ion State of Charge (SoC) measurement made by coulomb counting allow a measurement error of less than 1%, which allows a very accurate indication of the energy remaining in the battery. The built-in control circuit board has an overload protection function. Thus a typical 20k ID resistor will pull this pin to logic low state, indicating a valid battery connection. ), As this voltage-attraction is preventing the metal from dissolving, a She thinks this means well just have to charge more often; small yards no big deal. Memory effect is also reversible to a degree by carrying out a few proper charge/discharge cycles, Self-discharge rate is very low at normal room temperatures, High temperatures during use or charging can cause the batteries to explode, although most feature adequate safety features to prevent this, High cost compared to other battery types, Very safe and rarely explode or catch fire, Loses significantly more capacity in cold weather than Li-ion, Worse for the environment than Li-ion due to much more mined material being required, Lose voltage slowly as they discharge resulting in less power, Lose the ability to be recharged if left discharged for too long.
