Alternating current (AC), on the other hand, alternates directions a set number of times per second—60 times per second in the United States.

Power Sonic is a global supplier of VLRA rechargeable batteries. Established in 1970, they are a global company with over 1,000 people employed, with their corporate headquarters in the USA & major operations in UK, France, Mexico and The Netherlands. Batteries are always DC. That's why there is a positive and a negative terminal. It will always flow consistently from one terminal towards the other through the appliance using power. Electrical devices are made to function on either AC or DC, never both, without modification. May be discharged over a temperature range of -40 ºC to +60 ºC (-40 ºF to +140 ºF), and charged at temperatures ranging from -20 ºC to +50 ºC (4 ºF to +122 ºF). Rugged Construction The valve regulated, spill-proof construction of this battery allows trouble-free, safe operation in any position. There is no need to add electrolyte, as gases generated during charging are recombined in a unique "oxygen cycle". Long Service Life The higher Ah also means you'll be able to power more things for longer with less strain on the battery components. An easier workload will impact the longevity of the battery itself. Batteries allow flexibilityCommonly used in Alarm Systems, Emergency Lighting, Torches, UPS systems and other electrical systems Features: * Absorbent Glass Mat (AGM) technology for superior performance * Valve regulated spill-proof construction * Power/volume ratio yielding unrivalledenergy density * Rugged ABS plastic case and cover Many factors affect how long Ah will last in a battery. These include the rate at which the battery charges and discharges, ambient temperature and environment surrounding it, and the overall condition and age. Regardless of these variables, Amp-hours remain an important indicator of how long your devices can reliably run on one charge.

Commonly used in Alarm Systems, Emergency Lighting,Torches, UPS systems and other electrical systems AGM batteries are preferred when a larger number of amps are required. The life expectancy remains excellent in most cases if they are not discharged more than 60% between recharges and/or recharged fully every 3-6 months. Great experience buying from this retailer, item was shipped in a timely manner and was exactly as described."

Amp-hours, or Ah for short, are a unit of measure for a battery's energy capacity. This rating tells us how much current a battery can provide at a specific rate for a certain period. PS-1212 Power Sonic VdS and NCP approved valve regulated lead–acid battery. Same day courier dispatch. Open an accountfor dealer prices. Sold & delivered by Battco. Typically called the C-rate, they represent the battery's charging and discharging ability. Charts and formulas are available online to help calculate what the C-rate on a battery actually means for you. What's the difference between amps, ohms, and volts?

Our world revolves around electricity, a fact that becomes truer every day. A component of electricity availability that's becoming increasingly important is the battery. Batteries are in pretty much everything, from phones, to computers, to cars and even power supplies for homes. We've already covered amps. If we continue our river-in-the-canyon analogy, volts are like the pressure of the water through the canyon, the force pushing the current through.So, for example, if you have a fully-charged 5-Ah battery, it can provide five amps of current for one hour. If your device requires one amp of current to run at full speed, then the full charge would last about five hours, under ideal conditions, of course. Heat causes a loss of electricity, called voltage drop, which also lowers the force the voltage can provide and decreases the amperage that can get through. We minimize resistance through material choices, like copper or aluminum, and increasing the size of the conductors and components used. The less heat that is generated, the better for everything involved. PS-1212 is air transport approved, and meets all current requirements set forth by the D.O.T., I.A.T.A., F.A.A., and C.A.B. U.L. recognises model PS-1212 under file number MH20845, MH65205, & MH65234 Ohms are like the width of the canyon. The narrower you make the canyon (or wire), the harder the voltage has to work to push the same amount of amps through. The result is the generation of heat.

It's better to size up than to run the risk of undersizing. You don't want to run out of power on accident because you chose a 200Ah battery when you needed a 250. Does a higher Ah battery mean more power? Even though the Amp=-hours doesn't automatically mean the battery is more powerful by the numbers, sometimes it can equate to more power. In a higher Ah battery, the number and density of cells supplying the current and the heavier gauge of the conductors and components involved allow more current to move with less resistance. Amperage, also known as electric current, measures the rate at which electrons flow through a conductor or object. This rapid flow can be thought of as similar to water flow through a channel or canyon. The higher the amperage, the greater volume of electrons moving.If you hook something up to the wrong form of electrical delivery, it won't end well for your devices.
