Overload is when the tool is being used (power OUT FROM the battery) and the current draw goes up too high (for example, when the bit is too large or the torque too consistently high). In these cases, a well-designed tool turns itself off to protect both the tool and battery. A good battery-tool system monitors both aspects of this energy usage.

Learn MoreTo calculate the life of your battery, use the formula: Battery life (in hours) = mAh ÷ load current (in mA). For example, if you have a 9V battery with a capacity of 500mAh and a device that draws 100mA of current, the battery would last for approximately five hours (500mAh ÷ 100mA).
Learn MoreAs a result of multiple cells being connected in series, as with the use of a battery holder or pre-made battery packs, voltage increases, but amperage does not, which remains constant. If you have 8 AA batteries (2.8 ampere-hours each) connected in series, then the electric current flowing through them is equals to 0.14 amps per hour.
Learn MoreBattery Life = 225 milliamp hours/current In an application drawing a constant 1 microamp or less, this comes out to over 10 years. This might actually be true …

The AA battery (or double-A battery) is a standard size single cell cylindrical dry battery. The IEC 60086 system calls the size R6, and ANSI C18 calls it 15. It is named UM-3 by JIS of Japan. Historically, it is known as D14 (hearing aid battery), U12 – later U7 (standard cell), or HP7 (for zinc chloride ''high power'' version) in official documentation in the United Kingdom, or a pen cell.

(a) How many grams of gold (d=10.5g/cm3) are required? (b) How many minutes will it take to plate the object from a solution of AuCN using a current of 7.00 A? Assume 100% efficiency.
Learn MoreElectrolysis involves passing an electric current through either a molten salt or an ionic solution. The ions are "forced" to undergo either oxidation (at the anode) or reduction (at the cathode). Most electrolysis problems are really stoichiometry problems with the addition of an amount of electric current. The quantities of substances ...
Learn MoreIn contrast, electronic devices such as remote control, flashlights, and many others have a typical battery weight ranging from 7.0 to 45 grams. This statistical data on the battery weight in grams may vary based on the battery brands. What Is AAA Alkaline Battery Weight? The standard alkaline AAA battery weighs 11.5 grams or 0.41 ounces.

Instead, it represents the current the battery can generate in that charge cycle. In other words, a lower C-rating reduces the power the battery pack receives, whereas a higher rating provides more than enough …
Learn MoreA healthy car battery should typically show a voltage between 12.4 to 12.7 volts when the engine is off. Below 12.4 volts, it may need charging or be indicative of a failing battery. Can a battery have high voltage but low capacity? Yes, a battery can show a high voltage reading but still have a reduced capacity.
Learn MoreThe current produced by different battery sizes is also key. Voltage is equivalent to pressure or momentum, propelling the current out of the battery, while current is the actual power produced. Many electronic devices require additional current but may not require additional voltage. Typically, rechargeable batteries feature a slightly …
