Things That Trigger Carbon Monoxide Detectors Malfunctioning gas appliances – Any gas appliance can emit CO if it’s not getting the correct gas to air ratio. Air leaks – Ductwork leaks can pull CO into your home if you use … Continue reading →

An increase in the current is observed when the brightness of the bulb increases. If any series bulb is unscrewed, an open circuit is created and no current exists. Each device placed within the circuit provides a resistance to the … Continue reading →

Galaxy Note 7. On 2 September, Samsung suspended sales of the Galaxy Note 7 and announced an informal recall after it was found that a manufacturing defect in the phones’ batteries had caused some of them to generate excessive heat, … Continue reading →

Typically, a modern phone battery’s (lithium-ion) lifespan is 2 – 3 years, which is about 300 – 500 charge cycles as rated by manufacturers. How many years does a Samsung battery last? Lithium-ion batteries, like the ones you’ll find in … Continue reading →

A weak car battery can cause your auto air conditioner to function poorly or not at all. Car batteries need to have enough voltage to trigger the AC compressor, and while it may be strong enough to run the rest … Continue reading →

A normal amount of parasitic draw for newer cars is between 50-milliamp to 85-milliamp current draw. A normal amount of parasitic draw for older cars is a reading less than 50-milliamp. Anything past these amounts indicates an electrical issue and … Continue reading →

Laptop batteries usually cost a fortune (my 12-inch powerbook battery is like $130). This is why you should take the road less traveled and rebuild your battery. So what do you have to do? Well it s not too complicated, … Continue reading →

A 1-square-meter graphene sheet weighs only 0,77 milligrams. It is waterproof, repelling water and corrosion. It is chemically inert, does not react with oxygen in the air and does not oxidize. Can you make clothes out of graphene? New research … Continue reading →

The global solid-state car battery market is dominated by global players such as Toyota Motor Corporation (Japan), Solid Power (US), QuantumScape (US), Samsung SDI (South Korea), LG Chem (South Korea). Which company has the best solid-state battery technology? QuantumScape. QuantumScape … Continue reading →

Charge Voltage: Most Li-ion batteries perform at their best with a constant float voltage from the DC power supply. For example, a 48 volt Li-ion power plant may have an optimal float voltage of 54.0 volts DC. You can then … Continue reading →

How many times can a car battery be jump-started? It’s OK to jump-start a battery using another car once, but you shouldn’t try to crank it more than three or four times in a row if the dead car isn’t … Continue reading →

In long-term storage applications, a lithium battery should not be stored at 100% SOC, and therefore can be maintained with a full cycle (charged and discharged) once every 6 – 12 months to 30% – 70% SOC. What happens if … Continue reading →

Conclusion. The results are likely not surprising. Putting a body skin decal on your metal laptop – even a performant gaming rig – should not cause any changes in system temperatures or even the distribution of that energy. Is it … Continue reading →

Lithium Ion (Li-ion) Lithium Ion (Li-ion) are the new standard for portable power. Li-ion batteries produce the same energy as NiMH but weighs approximately 20%-35% less. They do not suffer significantly from the memory effect unlike their NiMH and Ni-Cd … Continue reading →

1.5 volts. AAA, AA, C, D batteries all are rated at 1.5 volts but besides the difference in physical size the amount of electric current they produce is also different. How many volts does a AAA battery put out? 1.5VGenerally, … Continue reading →
