# Quick Answer: Can You Use A 7.4 V Battery Instead Of 7.2 V?

## How long should a 9.6 V battery charge?

1.5 to 3.5 hoursHow long does it take to charge a 9.6v battery.

The time can vary depending on whether you are charging a 1600mAh pack or a 5000mAh pack.

In my experience it can take from 1.5 to 3.5 hours depending on the charge rate selected, the battery size, and how discharged the battery actually is..

## How long will a 5000mah LiPo last?

20-35 minutes5000mah is plenty. Quote: 20-35 minutes. depending on gearing and your driving habbits if your full throttle all the time less runtime if your doing a littl eof everything slow and fast your battery will last longer.

## How long does a 7.2 V battery take to charge?

RE: How long does it take for a 7.2 Volt battery to charge Like Inverted said, it depends on the bettery capacity. For example a 3000 mAh battery charged at 3 amps (1C) will take 1 hour. At 6 amps(2C), it will take 1/2 hour. If the wall charger works at say 1 amp, it will take 3 hours.

## Can I use LiPo batteries instead of NiMH?

Most people will eventually upgrade to LiPo after getting used to running their RC car or buggy on a NiMH battery. The main attractions to LiPo batteries are more speed, more “punch” off the line and more consistent power during the duration of the run compared to NiMH batteries.

## Can you charge a 9.6 V battery with a 12v charger?

RE: 12V charger for 9.6V battery? … If it is a TX pack I would say you should get a regular 50-55ma output wall charger. The 12V part is OK because a fully charged 8 cell pack will peak at around 12V. If it is a power pack, they should be charged in about 1/2 hour, they will heat up andthat means they are charged.

## Can you charge a 7.2 V battery with a 12v charger?

If it is a lead/acid “12V” 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.

## How long does a 9.6 V battery last?

My 9.6v 1200mah battery lats me about 2500 rounds, so a 9.6v 1600mah should last you about 3000-3500 rounds.

## Can you overcharge a NiMH batteries?

It is difficult, if not impossible, to slow charge a NiMH battery. … Harmful overcharge can occur when charging partially or fully charged batteries, even if the battery remains cold. The same scenario occurs if the battery has lost capacity and can only hold half the charge.

## How long do I charge a 7.2 V 1800mAh battery?

It takes 21.6 hours ( 21 hours and 36 minutes ) to charge or recharge aa size 1800mAh batteries with charger that has 100mA current output. In total 6.2 hours ( 6 hours and 12 minutes ) is needed to charge or recharge 1800mAh batteries with charger that has 350mA current output power.

## Can I use a 9.6 V charger for a 7.2 V battery?

Is it okay to charge a 7.2 V battery pack with a 9.6 V charger? No, definitely not! And, due to overly litigious Americans, you probably won’t be able to even attempt this with most consumer devices. It will sense that you plugged in a weird battery and refuse to work.

## What voltage should I charge a 7.2 V battery?

7.2 is nominal voltage. Charged it should be 8.7V for a six cell (1.45V per cell) ideally. At 1.5V per cell it gives 9V for six cell this is the Max, anything higher then a cell is going bad.

## Should you fully discharge NiMH batteries?

Do NiMH batteries need to be completely discharged before charging? No, NiMH batteries do not have a memory. They can be charged without adverse effect at any point regardless of their state of charge. Should I keep my NiMH batteries in the refrigerator / freezer for longer life?

## Does LiPo last longer than NiMH?

LiPo battery packs are composed of flat 3.7-volt cells. … LiPo batteries also sustain a higher voltage for a greater duration of each run, so your model will have more “punch,” go faster, and run longer with a LiPo than it would with a comparable NiMH pack.

## Do NiMH batteries explode?

If it doesn’t vent, the cell will breach and then explode. This is not any worse than what happens if you abuse LiIon or ever LiPO4 in a similar way. Don’t abuse batteries by improperly charging them. Even PbA, which is less volatile than NiMH or lithium chemistries, can do significant damage when improperly charged.
