Can we use 3000mah battery instead of 2000mAh?
It’s a stronger battery and lasts longer than the 2000 mah. I use these to power my B & D weed trimmer, blower, and car vac and they work great.
Can I use A battery with higher mAh?
Q: Can I use a higher rated mAh battery in my electronic device (i.e. 1800mAh vs. 2000mAh)? A: Yes, the mAh rating will give you longer run times between recharges. The higher rated mAh of a battery has no effect on electronic devices other than they allow longer term use.
Is it OK to use A lower mAh battery?
Using a lower rated mAh battery pack will most likely just mean its battery life is shorter. Second, for rechargeable batteries, it tells you something about the safe rate at which the battery can be charged, often stated in C’s. So a 1400 mAh battery might ideally be charged at 1.4A maximum.
Can I charge A 3.7 V battery with A 4.2 V charger?
You must never charge any 3.7V lithium ion battery using a fixed voltage 4.2V charger. Although this voltage is appropriate for the last part of the charge, if applied when the existing charge percentage is low then it is very likely to create excess current.
What is 2000MAH?
A 2000mAh rating means that the battery can supply 2000mA (or 2 amps) of current for the time period of the rating. A higher number means a battery with a higher capacity, and vice-versa.
Is it better to have a higher mAh?
Batteries with larger mAh ratings generally last longer than those with smaller ratings, assuming that the batteries are subjected to the same patterns of usage, but it may not mean a better battery. The milliampere hour represents a unit of electrical charge commonly used to measure battery capacity.
What does 1200mah mean?
What does battery “mAh” capacity mean? The mAh capacity rating refers to the storage capacity available for a particular battery. For example AA alkaline batteries typically have a capacity rating of over 2,500 mAh and AA NiMH batteries have rated capacities of only 1,200 to 2,000 mAh.
Can I use a 5V charger with a 3.7 V battery?
Generally, a 3.7V lithium battery needs an overcharge and overdischarge protection circuit board. Lithium battery with protection circuit board can be charged with 5V voltage(4.8V to 5.2V can be used). For 3.7V lithium batteries, the charge cut-off voltage is 4.2V and the discharge cut-off voltage is 3.0V.
Can I charge a 6V battery with a 5V charger?
To charge a 6 V lead acid battery requires 6.9 to 7.1 V. 5 V will just not work.
How long can a 10000mAh battery power a 200mah circuit?
So, for example, let’s say there is a circuit that consumes 200mA per hour. With a AA battery rated at 2000mAH, it can power the circuit for 2000mAH/200mA= 10hours. Now the same circuit powered by a D cell battery rated at 10,000mAH can power the circuit for 10000mAH/200mA= 50 hours.
How many milliamperes are in a 1900mAh battery?
Thus, a battery if a mAH specification of 1900mAH can provide 1900mA (milliamperes) for 1 hour of time. A battery with a mAH specification of 10,000mA can provide 10000mA for 1 hour of time.
What does Mah mean on a battery?
The mAH specification shows how long a battery will be able to last in a circuit, given the circuit’s power requirements, how much current the circuit demands. Being that the mAH is the battery’s life in terms of current capacity, the more mAH’s means the longer a battery can last, or the more current it can supply in a circuit.
How much current does a 380mah battery supply?
In this case, the battery supplies 380mA for 5 hours, since 380*5=1900. Or for other circuits, it can supply 190mA of current for 10 hours, since 190*10=1900. The product of the current consumed times the number of hours in use must equal to the mAH specification.
