# Can I Use A 3.7 V Battery Instead Of 3v?

## Are all AA batteries 1.5 V?

AA batteries are common in portable electronic devices.

The exact terminal voltage, capacity and practical discharge rates depend on cell chemistry; however, devices designed for AA cells will usually only take 1.2-1.5 V unless specified by the manufacturer..

## What voltage should I charge my 3.7 V battery?

## What are 3.7 V batteries used for?

18650 3.7 Volt lithium-ion rechargeable batteries are cylindrical batteries used in mainly for laptop battery packs, telephones, electronic cigarettes, flashlights and cordless power tools.

## What does 3.7 V battery mean?

For example, almost all lithium polymer batteries are 3.7V or 4.2V batteries. What this means is that the maximum voltage of the cell is 4.2v and that the “nominal” (average) voltage is 3.7V. As the battery is used, the voltage will drop lower and lower until the minimum which is around 3.0V.

## Can I use a 3.7 V battery instead of 3.6 V?

There is NO difference between 3.6 and 3.7 volt cells. It is simply a NOMINAL voltage, because every cell needs a reference point. In fact, either 3.6 or 3.7 volt cells have a fairly wide range.

## How long do 3.7 V batteries last?

Now a fully charged 1000mAH battery will last approximately 1000mAH/Load current hours. So if the load is 50mA, the battery would last about 1000/50= about 20 hours if fully charged but that is only an approximation.

## What is the voltage of 2 AAA batteries?

Most AAA, AA, C and D batteries are around 1.5 volts.

## What voltage is too low for a AAA battery?

Re: At what voltage are alkalines considered dead? For 1.5v AA or AAA primary batteries, 1.3v “under load” as tested by your DMM is considered dead. For 1.2v Nicad or NiMH AA or AAA rechargeable batteries, 1.0v “under load” is considered dead.

## Can I use 3.7 V battery instead of 3.2 V?

The ROV will run just fine using 3.7V batteries as opposed to 3.2V LiFePO4 batteries. However, most of the 3.7V batteries that you find in size 26650 (they are generally an “NMC” chemistry- Lithium Nickel Manganese Cobalt) don’t properly handle the current draw needed for the ROV.

## Can I use a 5v charger with a 3.7 V battery?

As we all know, if we use a 5V charger to charge a 3.7V cell, it will make the cell to heat and dangerous. But in fact you DON’T need a 3.7V charger. … So you can charge your 3.7V battery pack with the 5V charger, but be careful, choose one with the automatic circuit, just like the EasyAcc Power Bank.

## What does lr03 mean?

LR03 is the corresponding IEC classification, as AAA is the same battery but according to ANSI classification. The battery indication is dependable on the equipment.

## How do you charge a 3.7 lithium ion battery?

2 – The minimum voltage required to charge a 3.7v Li-Ion battery (to 3.7v), is 3.7v. A more practical voltage would be, 4.0v (3.7 < 4.0 < 4.2). A more "realistic" example of the second part of the first sentence would be 10 hours at 100mA.
