Absorbed glass mat (AGM) car batteries are referred to as dry cell batteries because fluid cannot escape. Although dry cell car batteries are expensive, they last longer than conventional wet cell batteries. Is a car battery a wet or dry … Continue reading →

Synthetic graphite is made by heating a variety of carbon containing substances (including petrochemicals, pitch, coal or acetylene). When super-heated (to temperatures higher than 4000°C) the carbon atoms rearrange themselves into layers to form graphite. How is natural graphite made? … Continue reading →

The first will be solid state batteries with graphite-based anodes, bringing improved energy performance and safety. In time, lighter solid state battery technologies using a metallic lithium anode should become commercially available. Do you need graphite to make batteries? Graphite, … Continue reading →

Modern vehicles can usually be jumpstarted but it’s a high risk job and mistakes can be costly. If you are in any doubt, contact us and we’ll send an expert. Only use quality jumper leads with spike protection, or a … Continue reading →

Natural graphite is mined from open pit and underground mine operations. Madagascar mines are mostly open pit, whereas Mexican, North Korean and Sri Lankan mines are predominantly underground. The United States does not produce any natural graphite. How is graphite … Continue reading →

Artificial graphite of bulk form is made by adding a binder to a carbon-based filler, i.e. coke and tar, followed by heat treatment [23] . In general, heat treatment is performed at 2500℃-3000℃ but higher temperature is required to achieve … Continue reading →

Power Converter/Charger Arguably, the most common way to charge RV batteries is through its onboard power converter or a battery charger when hooked up to a 120v electrical outlet, like on a shore power pedestal at a campground, for example. … Continue reading →

Normal AA/AAA batteries that have a voltage rating of 1.5V can supply constant 50mA current for a total capacity of 1800-2600 mAh charge and 3.90Wh of energy- Alkaline batteries. (Source: Wikipedia). How many amps is in a AA battery? At … Continue reading →

The load current for a small battery is 1A or less; for a starter battery it might be 50A or more. A voltmeter measures the open circuit voltage (OCV) with no load, followed by the second reading with a load; … Continue reading →

It holds a mediocre capacity of 1600 mAh (1.5 V) at 50 mA drain, limited by the low efficiency of the step-down converter. How many mAh is 1.5 V battery? Duracell AA Rechargeable Battery, Voltage: 1.5V, Capacity: 2500 Mah. How … Continue reading →

Lead acid batteries are not affected by the memory effect. The memory effect was limited to the nickel-cadmium batteries in the 70’s and 80’s. The memory effect was the occurrence when a nickel-cadmium battery would develop a cyclic memory that … Continue reading →

In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water. Do … Continue reading →

While not all compounds produce odors, several compounds do have recognizable odors, including: Cadaverine and putrescine smell like rotting flesh. Skatole has a strong feces odor. Indole has a mustier, mothball-like smell. Is there an odor when someone is dying? … Continue reading →

Even though most car batteries are only 6 or 12 volts, a 12-volt battery can produce as much as 600 amps. Amperage can be thought of as the volume of electricity that’s generated, but voltage can be thought of as … Continue reading →
