1.5 V KENTLI lithium battery in AA and AAA sizes KENTLI changes our everyday life. We use AA ("pencil") and AAA ("mini-pencil") batteries or batteries in many devices. Previously, we used traditional alkaline batteries, NiMh (nickel metal hydride) and NiCd (nickel cadmium) batteries. The nominal voltage of the alkaline battery is 1.5 V, and that of the NiMh and NiCd batteries is 1.2 V. In case of submersion, the voltage of all three products continuously decreases until the used device can still be operated. Lithium-ion technology has many advantages that NiMh and NiCd batteries do not have. The only problem is that the lithium-ion cell is 3.7V, which is too high a voltage for most everyday devices. Thanks to the revolutionary new technology, special electronics in KENTLI lithium-ion batteries reduce the 3.7 V voltage of lithium batteries to 1.5 V at the positive peak of the battery. Thanks to this, we can take advantage of all the advantages of lithium batteries, while the voltage remains at a stable 1.5 V until the battery runs out. Advantages over traditional batteries: Stable 1.5 V voltage, longer operating time. 5-10x faster charging time. Extremely low self-discharge. Leak-proof technology. It can be recharged approximately 1000 times in any state of charge. Multiple charging units No memory effect, the battery can be fully charged at any time. Protection against overcharge, overcurrent, overvoltage, overheating, deep discharge and short circuit. Less weight. A more environmentally friendly alternative. Kentli bridges the technological gap, enables the economical operation of all devices for which the 1.2V voltage is low and provides a much longer operating time with one charge.
