Now the orignial Clie battery came with 800 mAh and the volts is 5.2. All Rights Reserved. Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh. The higher the mAh rating the longer a battery will last. Note that rounding errors may occur, so always check the results.

Process/Mfg Tank Level, Battery Education a battery blog that discusses batteries, battery replacement instructions, battery buying guides battery technology, battery uses, and technical elements of batteries. Het is de totale hoeveelheid lading die bij 1 ampère in 1 uur heeft gestroomd: Hoewel ampère-uur geen SI-eenheid is, is het een praktische eenheid die gebruikt wordt bij elektrochemische processen zoals vergulden of verzilveren en voor batterijen. Critical Environments, We carry both 11 volt and 14 volt versions of the same battery in case you are unsure.Most laptop chargers are rated at 19 volts. So as we discussed early a nominal range is inherent in voltage ratings and slight variations in voltage generally do not impact the performance of your PDA. So the Watts would be: 41.6= 5.2 x 8. Oil and Gas, This is a back to basic articles on understanding a batteries electrical ratings. The explanation above applies to a single Li-Ion cell in series.

Men spreekt dan bijvoorbeeld van een accu met een capaciteit van 40 A (40 ampère) waar het gaat om een accu met een capaciteit van 40 Ah (40 ampère-uur).

Typically, PDA Batteries will use 1 to 3 Amps per hour, depending on the model's processor speed, screen size, screen brightness adjustment, usage, and other factors. Een ampère-uur is een eenheid voor elektrische lading. Ampere is an electrical unit used to measure the current flow towards the load. All Rights Reserved.

Many of our batteries have higher mAh ratings than original brand batteries. Test and Measurement, Use this page to learn how to convert between milliamperes and watts/volt. Convert mAh to time in hours.

We carry both 11 volt and 14 volt versions of the same battery in case you are unsure. Got feedback? 1 ampère-uur = 1 A × 3600 s = 3,6 × 10 3 C. Hoewel ampère-uur geen SI-eenheid is, is het een praktische eenheid die gebruikt wordt bij elektrochemische processen zoals vergulden of verzilveren en voor batterijen. Even if you mentioned the type of the battery, we couldn’t give you its voltage because it would depend on its state of charge. The extra voltage a charger has over a battery is so the charger can simultaneously power the laptop and charge the battery (if they had the same voltage rating the charger would only have enough power to run the laptop). So watt-hours is equal to milliamp-hours times volts divided by 1000: Calculate duration that milliamp hours lasts. De tekst is beschikbaar onder de licentie. 1 Whr is equal to 1 Watt of power used for an hour.Voltage measures the volume of electricity that is delivered to your laptop.

For example, if you have a 300mAh battery rated at 5V, the power is 300mAh * 5V / 1000 = 1.5Wh. Een ampère-uur is een eenheid voor elektrische lading.Het eenheidssymbool is Ah.Het is de totale hoeveelheid lading die bij 1 ampère in 1 uur heeft gestroomd: . Op wegwerpbatterijen laten fabrikanten dat meestal achterwege. PDA batteries with a 1 Amp hour rating could deliver ½ Amp of current for 2 hours, or they could provide 2 Amps of current for ½ hour. A battery’s current capacity (mAh) tells us nothing about its voltage (Volts). De capaciteit van een accu wordt bepaald door deze te ontladen met constante stroomsterkte bij een bepaalde temperatuur. What do the power ratings mAh, Volts, Whr and Watts mean? Home | Wh to mAh calculator milliamp-hours to watt-hours calculation. 1 ampere is equal to 1000 mA, or 1 volt/ohm. In control circuits, the most common resistor values are 250Ω & 500Ω, although any value can be used depending upon the device. Let's take a real question from a real person: "I have a sony clie PEG-NR70V/U PDA. Watts = Volts x Amps x k(one unit length of wire), Since the length of your PDA's wire inside the battery casing is difficult to know (unless you open the casing) let's just use a more common formula for Watts: (NOTE: DO NOT OPEN YOUR BATTERY'S CASING, EXTREME HARM WILL COME TO YOU). That is what is ultimately important to consumers as it is the capacity or amp hours that tells us how long we can expect a battery to deliver a charge before it runs out. So the Watts would be: Remember that I'm 1200 mAh is the same as 12 Ah and 800 mAh is the same as 8 Ah. Many of our batteries have higher mAh ratings than original brand batteries. There are no compatibility issues if your laptop and laptop battery have different voltage ratings.

Formula is (mAh)*(V)/1000 = (Wh). Scales, In control circuits, the most common resistor values are 250Ω & 500Ω, although any value can be used depending upon the device. There are no compatibility issues if your laptop and laptop battery have different voltage ratings. The megawatt [MW] to volt ampere [V*A] conversion table and conversion steps are also listed. Got feedback? Use this page to learn how to convert between milliamperes and volts/ohm. General Industrial, Amps, Volts, and mAh Batteries have electrical specifications that include its volt and milliAmp hour rating. ›› Quick conversion chart of mA to volt/ohm. Volts – or V – are an electrical measure of energy potential. Water and Wastewater,

All rights reserved. The battery that you show that would fit my unit is 1200 mah and 3.7 volts. Convert mAh to time in hours. voltage and mAh are two different, but interrelated, things. These higher mAh batteries are still 100% compatible with your laptop. 1 mA to volt/ohm = 0.001 volt… De eenheid ampère-uur wordt vaak onjuist afgekort tot ampère. Amps, Volts, and mAh Batteries have electrical specifications that include its volt and milliAmp hour rating. De nominale capaciteit geldt bij 20 uur en 20° C. Een nominaal 100 Ah accu kan dus 20 uur lang 5 ampère leveren bij 20° C. De capaciteit van een loodaccu is aanzienlijk minder bij snellere ontlading en/of lagere temperatuur. Converting mA to voltage is common in HVAC when working with pressure transducers. So the Watts would be: 44.4= 3.7 x 12. Volts on the other hand have to be within a nominal range (reasonable range) of each other. Free US Ground Shipping! These terms are abbreviated as we see in the following example: 3.7 V, 1600 mAh. General Industrial OEM, The original battery might be specified at 10.8 Volts, but customers using a universal part can operate their laptop safely at either the 10 or 11 Volt setting. Building Automation, Now back to the question we began with….. To understand the answer to the question let's look at a math formula for the complete formula of Watts…. Deze wordt meestal in Ah of mAh (= milliampère-uur) vermeld.

When a battery has two or more Li-Ion cells in series, the voltage is multiplied by the number of cells in series. Watt Hour or Whr is the amount of power used over a period of time (1 hour). Instant free online tool for megawatt to volt ampere conversion or vice versa. These terms are abbreviated as we see in the following example: 3.7 V, 1600 mAh.

Some of our batteries will have higher amp-hour ratings than the original battery found in your device and will not cause any incompatibilities. mAh ia a unit of electric power whereas V is unit of potential difference. Alternative Fuels,

Also, explore tools to convert megawatt or volt ampere to other power units or learn more about power conversions.

mAh Battery Life Calculator is an online tool used in electrical engineering to precisely calculate battery life. Amps – or A – is an abbreviation of Ampere, a 19th century French scientist who was a pioneer in electricity research. Note that rounding errors may occur, so always check the results.

E (Wh) = Q (mAh) × V (V) / 1000. HVAC/R, My Account

(Just as 1000mm equals 1 meter.) | Terms & Conditions | Privacy Notice | ISO 9001:2015 Certified | Prop 65. In the case of PDA Batteries, a milliAmp hour (mAh) is most commonly used notation system. De capaciteit is het product van de stroom en de duur van de ontlading.

Het is geen maat voor de energie in een batterij maar een gebruikelijke aanduiding voor de capaciteit van (oplaadbare) batterijen. Barometric, What do the power ratings mAh, Volts, Whr and Watts mean?

Many laptop makers have produced batteries that have differing voltage ratings.

As with all metric measurements, Amps can be divided into smaller (or larger) units by adding a prefix, in this case by adding an "m" to the amp hour we are renaming the amp hour to milli amp hour: mAh. One Amp equals 6.25 x 1018 electrons per second. Convert Voltage and Amps to mAh. HVAC/R OEM, Note that 1000 mAh is the same a 1 Ah. Now the orignial Clie battery came with 800 mAh and the volts is 5.2.

|, Resistor values are in OHMS (Ω is the symbol for ohms), VOLTAGE is the result of passing amps through a resistor.
