What is the difference between 5200mah

Either setup stores the same amount of energy and provides the same voltage, but you get to call one a "6-cell" and the other one just a "3-cell". Note that these voltages only apply to lithium polymer batteries, other battery technologies produce different voltages per cell you're probably familiar with 1. That was long. I think I explained everything correctly. Oh I know you ordered a Ferrari, but let's face it, you'll never get to full speed on these roads, so we've sent you a nice Ford.

Computers most certainly do not have a fixed resistance. You do not somehow magically get a longer runtime from your computer by reducing the voltage.

This is just plain wrong. This vendor sold you one thing and sent you a cheaper, less capable version of that thing, which may or may not work in your laptop. Fishbike explains the math above; it really is that simple. Send it back! You can't use Ohm's Law to relate battery voltage and computer current draw for various battery voltages. Ohm's Law applies to linear resistances, not to the switching power supplies you find between the battery and the rest of your computer's guts.

The output of a switching power supply will be a set of nice constant voltages typically 5V, 3. Those components, in turn, will draw as much current from the switching supply as they need from instant to instant. If you multiply the current being drawn from each of the switching supply's outputs by the voltage of that output, you get the total power being supplied on that output.

If a switching supply needs to draw 50 watts from a laptop battery, it will draw as much current as it needs to do in order to make that current in amps, multiplied by the battery's terminal voltage in volts, equal So in fact running your laptop off a lower-voltage battery will make it draw more current from that battery than it would from a higher-voltage one, not less.

The mAh rating is not the only thing that matters, and you should be concerned that you may not have understood what you were ordering. So even assuming your laptop will actually work on the lower voltage pack not necessarily a given; its switching supply might not be designed to cope with an input voltage that low it will certainly not run for as long.

Specifically, this claim from the vendor MAh Milliamperes represents the amount of stored energy in your battery. If they could sell you a MAh battery the size of a laptop pack, you should be designing the next generation of electric cars around it. To convert mAh to mWh, you need to multiply by voltage.

This is true only if the batteries being compared have the same voltage rating. If it's the same voltage rating as the original, this is true. If it's a lower voltage rating than the original, you need to a be sure that your laptop will actually work at that voltage and b multiply each pack's mAh rating by its voltage rating to generate mWh numbers that you can then use to compare likely runtimes.

This is completely bogus. In physical terms, voltage is more like a pressure than a volume. Closest electrical analogue for volume would probably be charge. If you multiply a pressure in newtons per square metre by a volume in cubic metres, you get an energy in newton-metres i.

An extremely sympathetic reading of the "voltage refers to volume" claim might be that the "volume" they're talking about is more like the loudness kind than the bigness kind, but that's an analogy so woolly as to be useless.

Far more likely that the whole "explanation" was written by a spotty youth who wasn't really paying attention in high school physics classes. The only thing they've got close to right is that more cells generally means more runtime, given more-or-less standard cell capacities. Max Capacity is a Premium laptop battery brand that is dedicated to only using the highest capacity cells available period.

No one will out last us and we will always be on the leading edge of technology. Providing corporate IT and consumers cost effect battery replacement options. Distributors Login here Open. What is Battery Cycle Life? This conversation is currently closed to new comments. If both batteries are the same physical size and the terminals are in identical locations, then the higher mAh battery is actually preferable more energy for the same size battery.

It will not adversely affect the computer as the voltage is the same. If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.

If ya buy a new battery then maintain it properly. OmniDyne Active Member. Click to expand After this, their performance drop. I bought it from one of online shopping sites here.

Cromewell Administrator Staff member. Darren Moderator Staff member. OmniDyne said:. But again, the newer battery is cheap, so I doubt you'll get the same level of performance or longevity compared to the original, no matter what you do.
