Best Answer

You can charge batteries with a different mAh rating if the charger is designed to handle them. You need to make sure of this, because Ni-Cad battery full charge state is not necessarily voltage dependent, but rather is dependent on detection of a change in voltage slope. If the power supply is not properly designed, you can overcharge the batteries, damaging them.

No. When putting multiple batteries in series or parallel the voltage and capacity needs to match.

Can I use a 3.7 v 750mah battery in place of a 3.7v 650mah battery?

It is always best to replace batteries with identical batteries. However if the replacement battery has the same voltage and the same physical construction (so it will connect electrically) it can usually be used as a replacement. The mah rating (capacity) only says how long it takes to charge and how long it will run between needing a charge. However some charging circuits might experience problems if this rating is significantly different from the original.


How many hours of charge can 600 mAh hold?

A 600 mAh battery can produce 75 mA for about 8 hours. If it is called upon to deliver 600 mA, it will last somewhat less than one hour. This is because ampere-hour ratings for batteries are, by standard agreement, normalized to an eight-hour rate. The actual rating is only a comparative rating, so you could properly say that a 900 mAh battery, for instance, will last 1.5 times longer than a 600 mAh battery.


How much time to charge 3000mah battery?

The milli-amp-hours rating has nothing to do with the voltage. The rating should be something like 3000 mah at 12V or 3000 mah at 1.5V. One common 3000 mAh battery is 3.0 volts; another is 3.7 volts. A common camcorder battery is 7.4 volts. Some DeWalt tools use 12 V 3000 mAh batteries.


Does mAh matter when replacing a battery?

mAh is a measure of the amount of charge stored in a cell or battery (set of cells). One (1) Ah is the equivalent of 1000mAh, and so the statement can be made that a cell with 2000mAh of stored charge can supply a device drawing one (1) mA for 2000 hours -- before needing replacement or recharge. It also means 1/1000*C/s*3600s.(1 milli= 1/1000, C=Unit for charge, s=seconds) which finally means that a battery rated 1mAh can hold a charge equal to 3.6 coulombs of charge.


How many mAh is a D size battery?

That would depend on the actual battery's specifications. I've seen some D cells rated as low as ~2000 mAh. However a full true D cell should have a rating between 10,000 mAh and 15,000 mAh.

What happens if you use different mAh batteries in electronics?

The battery with the larger mAh rating will last longer that the battery with the smaller mAh number will last in the same application.


How many watt hours in AA battery?

This question doesn't have a simple answer. It depends on the battery chemistry and construction. Somewhere in the battery's specification is the amp-hour rating. For AA size batteries, it is common to use milliampere-hour ratings (mAH). You need to multiply the mAH rating by 1.5 if you're figuring alkaline batteries, or 1.2 if you're figuring rechargeable batteries. Then divide the result by 1000 to get watt hours. Nicad cells are typically rated 500 to 1000 mAH. NiMh batteries typically have twice the rating of similarly sized nicad batteries. Alkaline batteries are typically rated at 2500-3000 mAH


How long do you have to charge a crosman pulse r73?

You should check the instructions for the answer. But an easy way of calculating the time needed is this super easy equation:Battery Capacity/Battery Charger Rate=Time to charge (in hours)For Example, a 1500 mAh Battery with a 250 mAh per hour charging rate will take 6 hours to fully charge.1500 mAh divide 250 mAh = 6 hrs.Or be the smarty pants and do it this way:the battery capacity x battery's mAh rating divided by the charger output (mA) x 1.4 (for NiCad batteries) = time (in hours).(1.5 for NiMh batteries)


Can a 4400 mAh battery replace a 4700 mAh one?

Milliamps Hour (mAh) is important because it's the easiest way to distinguish the strength or capacity of a battery. The higher the mAh, the longer the battery will last. Batteries with different mAh ratings are interchangeable. If your battery is rechargeable then the mAh rating is how long the battery will last per charge. Milliamps Hour is 1/1000th of a Amp Hour, so a 1000mAh = 1.0Ah Think of a cars gas tank. Voltage is how much gas is being used, and mAh is the size of the gas tank. The bigger the gas tank (mAh) rating the longer the device will run. If your battery is rechargeable, then think of the gas tank as refillable (rechargeable).


What is the mha rating of standard of AA alkaline batteies?

A non-rechargeable AA battery has a mAh capacity of about 400-900. Zinc Chloride batteries store between 1000 to 1500 mAh, while alkaline batteries can store between 1700 to 3000 mAh.


How many hours is 2460 mAh in a battery?

The 960 mAh battery rating is an eight-hour rating. This means you can expect eight hours of operation at 120 mA. Even though mAh means milli-ampere-hour, the rating is non-linear, and it is normalized to an eight-hour rating, so you should expect somewhat less than one hour of operation at 960 mA. Keep in mind that this is a relativistic rating, intended to be used to compare similar batteries with different mAh ratings. Actual performance could vary .

Which is better Lithium Ion or MAH batteries?

Lithium batteries last longer on a full charge, but are non-rechargable. Nickel metal hydride batteries are rechargeable but won't last as long per charge as lithium. Which is better depends on your needs.


Why do some batteries last longer than other?

Batteries have different sizes and amounts of power. -- I don't think that is what they want to know. Some batteries (of the same size) last longer because they all have different mAh levels. The more mAh a battery has, the more energy is stored in it. --

How do I know when your energizer chvc2 battery charger is finished?

An educated guess. Use this formula to determine approximate charge time.(the batteries mAh rating / chargers mA output current) * 1.2 .i.e. 1000mAh / 190mA * 1.2 = 6.315 hours. So these batteries would need to charge for approximately 6 - 7 hours.See related links below
