The voltage is the electrical potential difference between two points and is measured in volts (V). The current is the flow of electrical charge and is measured in amperes (A). Amp-Hour (AH) Rating . The amp-hour (AH) rating of a battery is a measure of its capacity. It tells you how much energy the battery can store and how long it will last. When choosing a battery

- 2 batteries of 1000 mAh,1.5 V in series will have a global voltage of 3V and a current of 1000 mA if they are discharged in one hour. Capacity in Ampere-hour of the system will be 1000 mAh (in a 3 V system). In Wh it will give 3V*1A = 3 Wh.
Car Battery Charger Amps: How Many Do I Need? Fortunately it''s not that difficult to work out how many Amps you need to charge your car battery. Here''s exactly how to get the right size of charger. 1) Get the capacity of your car battery (in Ah) Most of the time, it''ll be written on your car battery. It''s the number of Amp-hours the battery can deliver, and is expressed as a number of
The amount of voltage needed to charge a phone can differ based on the device and battery. Most phones with Lithium-ion batteries need a voltage of around 5 volts for charging. Check your device''s specifications for the recommended charging voltage.
Your battery is 500 milliamp-hours, so charging at 0.1 C means charging at 50 milliamps. Since the battery voltage is higher than the output of your "charger" (wall wart power supply) you will have to either use a different
I still have a 7.2V "racing pack" charger specifically designed for such a job. A 9V adaptor would over-charge the pack, quickly damaging either the adaptor or the battery.
The correct battery charger should offer the appropriate charging profile for your battery, with the proper charging voltage and charging current. Battery chargers are rated in Amps, and they also indicate what

For instance, if you have a small motorcycle battery, you''ll want to charge it at around 2 amps; if you have a larger battery, you can charge it at up to 10 amps. What Amp to Charge Motorcycle Battery? One of the most common questions we receive here at BatteryStuff is, "What size battery charger do I need to charge my motorcycle
I suspect it is undercharging as it only has a 7.2v output, a battery pack needs a much higher voltage to be able to charge. That charger should take between 1.5 and 2 hours to charge that battery from flat.
I suspect it is undercharging as it only has a 7.2v output, a battery pack needs a much higher voltage to be able to charge. That charger should take between 1.5 and 2 hours
Using a charger designed specifically for a 7.2V battery pack ensures that the charging voltage and current are appropriate. Manufacturers typically provide guidelines for
I still have a 7.2V "racing pack" charger specifically designed for such a job. A 9V adaptor would over-charge the pack, quickly damaging either the adaptor or the battery. You would need to limit the current to no more than 400mA (C/10).
If you expand the "Other battery parameters" section of this battery capacity calculator, you can compute three other parameters of a battery. C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah. A 2C battery would need just half an hour to
A fully charged 7.2V battery pack should have a voltage close to 8.4V for NiCd or NiMH batteries, or around 7.6V for Li-ion batteries. This voltage indicates that the cells
I''m about get a couple of 7.2v 3300mah stick packs, and was wondering about the proper "care and feeding" of nimh packs. Charge at C/10 for the first charge .33A (.3A is close enough) for 12-16 hours or until approx. 20 F above ambient and 1.45 volts per cell (
Using a charger designed specifically for a 7.2V battery pack ensures that the charging voltage and current are appropriate. Manufacturers typically provide guidelines for compatible chargers. As noted in a study by the Institute of Electrical and Electronics Engineers (IEEE), chargers that match the battery specifications lead to optimal performance and
Using the battery pack calculator: Just complete the fields given below and watch the calculator do its work. This battery pack calculator is particularly suited for those who build or repair devices that run on lithium-ion batteries, including DIY and electronics enthusiasts. It has a library of some of the most popular battery cell types, but you can also change the parameters to suit any
Battery size chart for inverter. Note! The input voltage of the inverter should match the battery voltage. (For example 12v battery for 12v inverter, 24v battery for 24v inverter and 48v battery for 48v inverter .
Your battery is 500 milliamp-hours, so charging at 0.1 C means charging at 50 milliamps. Since the battery voltage is higher than the output of your "charger" (wall wart power supply) you will have to either use a different power supply or use some circuitry to boost the voltage to more than 7.2 volts and limit the current to 50
A very simple answer is enough voltage to yeild the desired amount of current to flow into the battery. The voltage applied will always have to be slighly above the battery voltage at any given moment in order for the battery to charge. The open circuit voltage of a simple charger may be very high relative to the desired battery
Set the NiMH battery charger to 7.2 volts. Don''t attempt to exceed this, as you will damage your battery and, more importantly, it could be dangerous. Insert the jack connector from the charger into your NiMH battery.
The correct battery charger should offer the appropriate charging profile for your battery, with the proper charging voltage and charging current. Battery chargers are rated in Amps, and they also indicate what battery voltage you should use. So if you want to charge a 12V battery, use a 12V charger. For a 24V battery, use a 24V
A very simple answer is enough voltage to yeild the desired amount of current to flow into the battery. The voltage applied will always have to be slighly above the battery voltage at any given moment in order for the battery to charge. The open circuit voltage of a simple
Set the NiMH battery charger to 7.2 volts. Don''t attempt to exceed this, as you will damage your battery and, more importantly, it could be dangerous. Insert the jack connector from the charger into your NiMH battery. Plug in the charger to the main power supply, then check the charge rate again and make sure your battery is being charged.
A fully charged 7.2V battery pack should have a voltage close to 8.4V for NiCd or NiMH batteries, or around 7.6V for Li-ion batteries. This voltage indicates that the cells inside the pack are fully energized.
I have a cell phone battery that has the following written on one side: 3.7 V 1000mAh; Limited charge voltage: 4.2 volts ; I understand that the first line means, that the battery will always give 3.7V (at least in theory) at its output terminal. Also the battery will last for 1 hour if the mobile circuitry draw 1000mA.
The charging voltage needs to be a bit higher than the nominal voltage of the cell to kickstart the opposite redox reactions, For example, in lead acid batteries, the nominal voltage of each cell is 2V. Therefore, the minimum charging voltage needs to be around 2.25V to 2.3V per cell (13.5V to 13.8V for a 12V battery).
Therefore, the minimum charging voltage needs to be around 2.25V to 2.3V per cell (13.5V to 13.8V for a 12V battery). A voltage that’s too high can lead to undesired side reactions like the formation of gas (“gassing voltage”) towards the end of the charging process of lead-acid batteries.
Charging a 7.2-volt NiMH battery is a simple task so long as you ensure that you set your charger up correctly. Set the NiMH battery charger to 7.2 volts. Don't attempt to exceed this, as you will damage your battery and, more importantly, it could be dangerous. Insert the jack connector from the charger into your NiMH battery.
A 9V adaptor would over-charge the pack, quickly damaging either the adaptor or the battery. You would need to limit the current to no more than 400mA (C/10). Without knowing the specification of the adaptor, it's hard to tell how sophisticated that current limiter would need to be.
The voltage applied will always have to be slighly above the battery voltage at any given moment in order for the battery to charge. The open circuit voltage of a simple charger may be very high relative to the desired battery voltage but because of it's design only a limited current will flow.
That would be a waste of money. Instead, choose a battery charger with an amperage rating compatible with your battery’s recommended charging current range. In addition, even if the charger tried to deliver a charging current higher than what the battery requires, the battery’s BMS wouldn’t allow for this current to reach the battery.
