A 6v battery has 4 fairly large cells in in series and can deliver current for a long time for example to light a flashlight bulb. The 9 v has more very small cells in series and is much less … Continue reading →

A 4kW solar panel system can cover the energy needs of a family of 3 or 4. Installing such a system will not only save you on electricity bills but will also make your home more environmentally friendly and make … Continue reading →

Home Professionals lay this out clearly stating that “the average 2,000 sq. ft. U.S. home uses around 1,000 kWh of energy per month or about 32 kWh per day.” But again, it’s not so clear cut. How many kw do … Continue reading →

Even iron-phosphate (LFP) batteries—which have helped keep average costs down since they are cheaper to produce than lithium-ion batteries that use more expensive materials like cobalt—will see prices increase about 15% next year due to the lithium shortage, he explained. … Continue reading →

Once upon a time, the 3LR12 4.5V battery was a very common battery used in various applications, but nowadays it is mostly used in flashlights, toy remote controllers, and similar applications. What is a 4.5 V battery used for? 3LR12 … Continue reading →

Take the load in amps and divide it into the wattage. Let’s arbitrarily say that’s 10 amps. In that case, 10,000W / 10A = 1,000V. If the individual cells are rated at 1.5V, then 1,000 / 1.5 = 666.667, or … Continue reading →

Normal Operation, Overcharging and Faulty Systems Under normal operating circumstances, it is possible for a flooded lead acid battery to maintain a hydrogen and oxygen concentration above the level where an ignition source may cause an explosion. Why do AGM … Continue reading →

Trickle Charger 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 … Continue reading →

How do you convert 9V to 3V? To reduce a 9V battery to 3.3 volts, use a zener diode, such as a 1N746 or a 1N4728A. Choose the appropriate one based on how much power it can dissipate. A 1N4728A … Continue reading →
