Vitamin D3: A vitamin produced by the body when exposed to ultraviolet light or obtained from dietary sources. Vitamin D3 is a hormone that has an important role in calcium and phosphorus metabolism. Technically, vitamin D3 is not a vitamin … Continue reading →

Once the engine is started, we no longer need the battery (again, from an engine point of view) as long as the alternator / regulator continues to provide the necessary power to the ECU. The ECU however needs a stable … Continue reading →

NiMH Chemistry Charge rates and times are: Rapid Charge: A charger can provide a rate of 0.3-0.5C as it will take 3-6 hours to charge. Fast Charge: Charger can be set at 1C charge rate as it can take from … Continue reading →

Typical charge current for AA batteries should be around 120 to 150mA to avoid any overcharging when left on charge for a long period. Unfortunately, some manufacturers allow too higher charge current (>150mA) and this can reduce the life of … Continue reading →

D cells are typically used in high current drain applications, such as in large flashlights, radio receivers, and transmitters, and other devices that require an extended running time. A D cell may be either rechargeable or non-rechargeable. Its terminal voltage … Continue reading →

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A. Is … Continue reading →

Copper is not an alkaline earth metal, it is a transition metal, also known as a coinage metal. Is copper a base or acid? -Generally oxides of metal are basic in nature whereas oxides of non-metal are acidic in nature. … Continue reading →

Copper hydroxide is dissolved by aqueous ammonia, forming a complex salt (tetra-ammonium copper hydroxide). The refined linters are added to copper ammonium solution which contains copper hydroxide as a precipitate. Cellulose forms a complex with tetra-ammonium copper hydroxide which dissolves … Continue reading →

Battery materials are refined and put into a cell, and will still remain in the cell at the end of their life, when they can be recycled to recover its valuable materials for reuse over and over again. What happens … Continue reading →

If you can’t recharge the battery you have, the next best (and probably only) thing you can do is swap it out for a new one. The process is simple as long as you take some cautious steps, so here’s … Continue reading →

Environmentally friendly Rechargeables are highly effective in reducing your carbon footprint, as one rechargeable battery can replace thousands of single-use batteries. Does rechargeable batteries harm the environment? “Rechargeable batteries can contain metals that may be harmful to the environmental if … Continue reading →

LEDs are wired in series-parallel just like the traditional bulbs we described above. Unlike incandescent lights, however, LEDs do not typically make use of shunts. Are Christmas lights series or parallel circuits? Christmas lights are wired as a “series” of … Continue reading →
