## Do you need a special battery charger for lithium batteries?

You do not need a specific lithium battery charger.

### Can I charge a 7.2 V battery with a 5V charger?

Can I charge batteries at 7.2 V? Answer: Even if you apply 7.2v at the Input, this circuit normalizes the Output to 5v and to charge a 7.2v battery you need to apply a greater voltage like 8v-10v.

#### Can I charge a 7.4 V battery with a 5V charger?

Regardless of the nominal power of the 5V power source, the module can safely and efficiently charge the lithium battery.

What voltage should I charge a 7.2 V battery?

between 1.4 to 1.6 V per cell
If the voltage goes beyond a certain specific limit, then it might cause multiple risks; therefore, it is essential to know the voltage at which you should charge your 7.2V NiMH battery. The range of charging voltage is between 1.4 to 1.6 V per cell.

What is the best way to charge a lithium-ion battery?

Simple Guidelines for Charging Lithium-based Batteries

1. Turn off the device or disconnect the load on charge to allow the current to drop unhindered during saturation.
2. Charge at a moderate temperature.
3. Lithium-ion does not need to be fully charged; a partial charge is better.

## Can you use a trickle charger on a lithium battery?

It is important to note that trickle charging is not acceptable for lithium batteries. The Li-ion chemistry cannot accept an overcharge without causing damage to the cell, possibly plating out lithium metal and becoming hazardous.

### Can I charge a 7.5 V battery with 12V charger?

If the charger with any output voltage (must be at least higher than battery voltage) delivers the current below the rated, then it’s safe to recharge the battery.

#### Can I charge a 7.2 volt battery with a 12 volt charger?

If it is a lead/acid ā12Vā charger, it likely has a nominal output voltage of higher than 12 volts, and if it is above, say, 14.5V, you could charge two 7.2V batteries in series. If the output is actually 12.0V, then you may still be able to charge one battery if you include a resistor in series.

What charger do I need for my LiPo battery?

For the vast majority of LiPos, the Charge Rate is 1C. The equation works the same way as the previous discharge rating, where 1000mAh = 1A. So, for a 3000mAh battery, we would want to charge at 3A, for a 5000mAh LiPo, we should set the charger at 5A, and for a 4500mAh pack, 4.5A is the correct charge rate.

Can I charge a 7.2 V battery with a 6V charger?

A 6V supply will not charge a 7.2v battery. It sounds like you are talking about little DC power supplies or battery eliminators, not a battery charger. You definitely want to get a charger designed for charging NiCd and NiMH batteries.

## Can you overcharge a lithium-ion battery?

Li-ion cannot absorb overcharge. When fully charged, the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium and compromise safety. To minimize stress, keep the lithium-ion battery at the peak cut-off as short as possible.
