Nokia 1661 2 Not Charging


»The charging circuit of the device itself is responsible for the quality of charging the battery, and not the charger used, as many people think. The only task of charging is to provide the necessary current, however, it will be dosed by the charging circuit of the device itself. However, a weak charger (giving out insufficient charging current) can be the reason for too long a charging process, for example, a communicator with a powerful processor that has a large current consumption. If you are the owner of the device, always try to use the original charging, or purchase a charger that produces a current of at least 1A (1000 mA).

»The battery energy density for the Nokia 1661, made using Li-Ion technology (based on lithium ions), is almost twice the energy density in NiCd batteries.

»For Li-Ion batteries, full discharge is very harmful. In this case, the battery life drops sharply. Try to prevent the phone or camera from completely discharging and always, when you come home or to work, put your Nokia 1661 to charge. This will extend the battery life. On the contrary, overcharging is useful (for example, if you left the device to charge overnight) and, as confirmed by experience, it can even contribute to an increase in the nominal battery capacity by 2-3%.

»The battery discharge sensor works similarly to the water flow sensor in your bathroom: when charging, it measures the amount of current that “flowed in” into the battery, and when discharged. “leaked out”. Based on this information, the processor of the telephone or digital camera displays a battery indicator. This type of measurement is called current measurement. Since the sensor remembers the amount of current that has entered the battery, it will almost certainly be mistaken if the battery is replaced. That is why the new battery should be fully charged several times. This is how the sensor in Nokia 1661 enters normal operation mode.

»Most people when buying a mobile phone or camera do not think about which battery they use and face problems with operation or replacement after purchase.

»The new Li-Ion battery does not immediately reach full design capacity. Before this happens, it is necessary to perform 3-4 full charges (for example, leaving the device to charge overnight). Contrary to popular belief, for such batteries is not needed and even harmful “buildup”, i.e. full charge / discharge cycles. So, a full charge positively affects the Li-Ion battery, but a full charge can ruin it.

Nokia 1661 2 Not Charging

»The Nokia 1661 charging circuit charges the battery according to a complex algorithm: if it is heavily discharged, it is charged with direct current, if partially pulsed, with alternating charge / discharge cycles for each second of charging.

»Your new Li-Ion battery for Nokia 1661 has an element charge temperature control circuit. Rather, a temperature sensor (digital thermometer) is located in the battery, which reports the battery temperature to the charging circuit located inside the device, which, in turn, decides how to charge the battery, or it can completely stop charging in case of severe overheating or severe overcooling (for example, in the cold).

»Lithium is the lightest of all metals and has maximum electrochemical potential, which is why battery for Nokia 1661 made using Li-Ion technology.

»Li-Ion battery technology is constantly improving, it happens approximately every 6 months.

»The lithium-ion battery is an improved version of the lithium battery. Initially, manufacturers refused to use lithium batteries, as they were subject to overheating, after that the Li-Ion batteries that we use today were developed.

»The first experiments to create lithium-ion batteries were undertaken back in 1912, that is, long before the advent of cell phones and digital cameras. However, only after seven decades, they began to be used for the first time in Nokia products.
