# Can I replace a 1.2 V battery with a 1.5 V battery?

### Can I replace a 1.2 V battery with a 1.5 V battery?

So, for the most part, 1.2 volt rechargeable batteries will work as a replacement for 1.5 volt Alkaline batteries, with a few exceptions.

### What is the difference between 1.2 volt and 1.5 volt batteries?

What’s the difference between 1.5 V and 1.2 V? 1.5 V is the nominal voltage for dry batteries, and nickel-metal hydride batteries have a nominal voltage of 1.2 V. Dry batteries have a slightly higher voltage than the actual working voltage required by the appliance.

### What will happen to the current If you replace the battery with a 1.5 V battery?

What happens to the current in a circuit if a 1.5- volt battery is removed and replaced by a 9-volt battery? The current would increase. … The relationship between voltage and current in a circuit is that the greater the voltage the greater the current and vice versa.

### Can I use 3.7 V battery instead of 1.2 V?

A similar sized 3.7V lithium would put out only about 1.2mAh. This means that the circuit designed for the 1.5V battery would probably have a higher current draw than the lithium would be able to handle. So the battery would probably overheat and possibly explode.

### Can I use a 1.5 V battery instead of 1.2 V?

In practice the batteries can be used interchangeably in sets. Electronic devices are usually made to run from cell voltages of 1.0 to 1.5 volts. While primary cells gradually drop in voltage from use, they start at 1.5 volts, drop to 1.2 and continue to 1.0 where the appliance stops working.

### Can you use 18650 battery instead of AA?

Can I use AA batteries instead of 18650? – Quora. NO. AA batteries run at 1.5 volts average for around 1800 Milliamp hours while 18650s run at around 3.7 volts, and around 3000 milliamp hours. you could use AA rechargeables, but you would need many more of them for the same purpose, and they wear out much faster.

### What is a 3.7 volt battery 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.

### Are all rechargeable batteries 1.2 V?

Not all rechargeable batteries have a nominal voltage of 1.2V; it is specific to a few chemistries that happen to be popular. According to Wikipedia, the following rechargeable battery chemistries have cell voltages of 1.2V: Nickel-iron.Feb 26, 2016

### Why is a NiMH 1.2 V?

Because they have different cell chemistries. The Nickel Metal Hydride cell has a 1.2 volt nominal voltage as does the NiCad cell. The alkaline cell chemistry has a 1.5 ( or 1.6 ) volt nominal output. NiCads and NMH cells are capable of large current while the alkaline cell has more limited current capability.

### What happens if I replace a 1.2 volt battery with a 1.5 volt battery?

Usually, no problem. Most devices work better @ 1.5. Some devices compensate by adding an extra slot to compensate for the voltage lossvoltage lossVoltage drop is the decrease of electrical potential along the path of a current flowing in an electrical circuit. … Voltage drops in the internal resistance of the source, across conductors, across contacts, and across connectors are undesirable because some of the energy supplied is dissipated.https://en.wikipedia.org › wiki › Voltage_dropVoltage drop – Wikipedia.. IE, 5 batteries when using nicads or nimh .

### Are there 1.5 V NiMH batteries?

Traditional AA/AAA rechargeable batteries have always been the world of NiMH batteries, especially the appearance of Eneloop. … Its principle is a 3.6/3.7V lithium battery be stepped down to a 1.5V constant voltage output through a built-in circuit module.Jun 4, 2020

### How many amps is a 1.2 V battery?

A typical alkaline or NiMH battery in the standard “AA” size has about 2000 to 3000 mAh (or 2 to 3 Ah). With a cell voltage of 1.2 V to 1.5V, this corresponds to 2 to 4 Wh per cell. If connected in series the voltage available would be 13.5 V at 3000 mAh , if in parallel it would be 1.5 V at 27,000 mAh .
