Sure. You actually need a little more than the rated battery voltage to charge a battery. Half a volt out of 9 is only about 5% which should be about right. Just check the charge current to make sure it … Continue reading →

How do I test an AC DC adapter? Testing your power supply Plug your power supply into an AC outlet. Red probe goes into the tip. Turn on your multimeter and set it to read DC voltage. Take the red … Continue reading →

Batteries can be charged manually with a power supply featuring user-adjustable voltage and current limiting. I stress manual because charging needs the know-how and can never be left unattended; charge termination is not automated. Can I use a power supply … Continue reading →

2. Larimar. Following the in the footsteps of Tanzanite, Larimar can only be found in one small area in the Dominican Republic and nowhere else. It’s a rather rare blue specie of the mineral pectolite. What is the second rarest … Continue reading →

The minimum lifespan most manufacturers expect from lithium-ion batteries is around 5 years or at least 2,000 charging cycles. But, if well cared for and used in proper conditions, lithium-ion batteries can last as long as 3,000 cycles. Can a … Continue reading →

Interlock is a current and voltage loop mechanism used to detect tampering or opening of the high-voltage equipment or service disconnect switch. This design covers generating and monitoring mechanism of high voltage interlock system. How does high voltage interlock work? … Continue reading →

The truth is that any lead acid battery, be it a Gel Cell, AGM or flooded batteries such as DCBs, should be cut-off at 11.6 volts. Not doing so increases the risk of damage to the battery and if taken … Continue reading →

Most deep cycle batteries can last up to six years with proper care and charging (depending on the frequency of use). It’s up to you to make sure that your battery isn’t being damaged by your charging routine. How long … Continue reading →

Tools 7 inches or shorter (measured from end to end when assembled) may be allowed in carry-on baggage. Power tools and all tools longer than 7 inches (measured from end to end when assembled) are prohibited in carry-on baggage; these … Continue reading →

The only nickel-based cell that has been exploited for utility applications is the nickel cadmium cell. Nickel cadmium batteries have higher energy densities and are lighter than lead-acid batteries. They also operate better at low temperatures. Is cadmium still used … Continue reading →

In the human body, solutes vary in different parts of the body, but may include proteins—including those that transport lipids, carbohydrates, and, very importantly, electrolytes. Often in medicine, a mineral dissociated from a salt that carries an electrical charge (an … Continue reading →

Second method: You have to look at the top of the battery. Usually, batteries have removable tops or caps unless you find “sealed” written on the label if they are liquid lead-acid type. Gel-filled type and AGM lead-acid batteries are … Continue reading →

An electrolyte panel, also known as a serum electrolyte test, is a blood test that measures levels of the body’s main electrolytes: Sodium, which helps control the amount of fluid in the body. Chloride, which also helps control the amount … Continue reading →
