A 7.2 volt battery is a type of lead-acid battery, which means it needs to be charged before use. The charging process for a 7.2 volt battery is different than other lead-acid batteries, and it’s important to follow the instructions in your owner’s manual to ensure proper charging. Most 7.2 volt batteries will take between four and six hours to charge fully.
If you’re wondering how long to charge a 7.2 volt battery, the answer is typically around eight hours. However, it’s always best to check the manufacturer’s instructions first to be sure. Overcharging a battery can shorten its lifespan, so it’s important not to overdo it.
Once your battery is fully charged, unplug it from the charger and store it in a cool, dry place until you need it again. If you’ll be storing the battery for an extended period of time, make sure to check on it every few months or so to make sure it’s still in good condition. With proper care, your 7.2 volt battery should give you years of reliable service!
How Long Does It Take to Charge a 7 Cell Nimh Battery?
Assuming you are talking about a AA size 7 cell NiMH battery, it will take approximately 14 hours to charge from empty using a standard household outlet. This time can be reduced by using a faster charger or by increasing the voltage, but doing so also increases the risk of damaging the battery.
How Long Does It Take to Charge a 2000Mah 7.2 V Battery?
Assuming you are talking about a 2000mAh 7.2V Li-ion battery, it would take around 2 hours to charge it using a standard 1000mA (1A) charger. If you are using a faster charger that can output 2000mA or more, then the charging time would be halved.
How Long Does It Take to Charge a 7.4 V 1200Mah Battery?
Assuming you are talking about NiMH batteries, it will take about 4.5 hours to charge a 7.4V 1200mAh battery using a standard charger. If you are using a faster charger, it will take less time. For example, if you are using a 1A charger, it will only take 1.2 hours to charge the same battery.
How Long Should You Charge a 7.4 V Battery?
Assuming you are talking about a 7.4V Li-ion battery, the answer is not as simple as how long to charge it, but rather it depends on several factors. The capacity of the battery, discharge rate, and cut-off voltage all play a role in how long to charge a 7.4V battery.
Capacity is usually measured in mAh (milliamp hours) and will be listed on the battery or package.
This is important because a higher capacity means that the battery can store more power and will therefore take longer to charge. For example, if you have two batteries – one with 1000mAh and one with 2000mAh – it will take twice as long to charge the 2000mAh battery. The discharge rate is also important because it affects how much power can be drawn from the battery at once.
A lower discharge rate means that less power can be drawn from the battery, so it will take longer to charge. For example, if you have two batteries – one with 5C and one with 1C – it will take five times as long to charge the 1C battery. Finally, the cut-off voltage also plays a role in how long to charge a 7.4V Li-ion battery.
Most chargers will stop charging when the voltage reaches 4.2V per cell, but some chargers may go up to 4.35V per cell. A higher cutoff voltage will mean that the charger can put more energy into the cells and thus shorten charging time accordingly.

Can I Charge a 7.2V Battery With a 12V Charger
If you’re like most people, you probably have a few old batteries lying around the house. And if you’re like most people, you probably also have a charger that came with your phone or other device. But what happens if you need to charge a 7.2V battery with a 12V charger?
The good news is that it is possible to charge a 7.2V battery with a 12V charger. However, there are a few things you need to keep in mind before doing so. First of all, make sure that the charger is rated for the voltage of the battery.
If it’s not, then you could damage the battery or the charger. Second, be aware that charging times will be slower than if you were using a dedicated 7.2V charger. Finally, make sure to disconnect the charger once the battery is fully charged; otherwise, you run the risk of overcharging and damaging the battery.
With those caveats in mind, charging a 7.2V battery with a 12V charger is perfectly safe and can be done in a pinch if necessary. Just remember to take care when doing so and always follow manufacturer’s instructions first and foremost!
Assuming you are referring to a lead acid battery, it should be charged for 24 hours the first time. After that, it can be left on a charger for up to 72 hours.
