The charge voltage of lithium batteries is 4.2V, or for 2 cells, 8.4V – so that’s good. Typical lithium batteries have a minimum charge time of 1 hour, so a 0.9A charger should be slow enough – at 1 hour 20 minutes (0.9A in to 1.2Ah) – so that’s also good.
What amp should I charge my 8.4 V NiMH battery?
battery charging
And on 3 amperes, one hour. But keep it on about 1,5 amperes like Rob says. As soon as you get 8 to 10, maybe 12 cycles on the pack, I would bump charge rate to at least 3amps.
What amp should I charge my NiMH battery?
4 to 5 amps
The high-performance NiMH battery chargers with a minimum charge rate of 4 to 5 amps in one cycle are required and needed to charge the high capacity NiMH batteries completely that varies around 3000 to 5000 mAH.
What voltage should I charge my battery at?
The typical charging voltage is between 2.15 volts per cell (12.9 volts for a 12V 6 cell battery) and 2.35 volts per cell (14.1 volts for a 12V 6 cell battery). These voltages are appropriate to apply to a fully charged battery without overcharging or damage.
What voltage are NiMH batteries?
1.2 volts
The industry standard for the rated voltage of a NiMH cell is 1.2 volts. This value is the nominal voltage of a cell that is discharged at a rate of C/10 at a temperature of 25°C (77°F) to an end voltage of 1.0 volt. This industry standard is used primarily to call out the rated voltage of battery packs.
How long does a 8.4 V NiMH battery last?
They charge quickly and each one provides 30-35 minutes of run time.
Can I charge an 8.4 V battery with a 12v charger?
The danger in this situation is the fact that connecting 2 units of 12 Volt batteries in series will give 24 Volts of potential that could back feed into the charger and damage the components if there is no diode. No, a 12 Volt charger cannot charge two 12 Volt batteries in series.
How long does it take to charge a 5000mAh NiMH battery?
So, how long does it take to charge an 800-5000mAh NiMH battery? The charging time can vary anywhere between 2.5-15 hours.
How do you know when a NiMH battery is fully charged?
Usually, a fully charged battery would display a voltmeter reading of around 1.5 volts. That means your battery is in good shape if your voltmeter shows a voltage anywhere between 1.3-1.5 volts. 4)A strong indication that your battery has excessive voltage is any voltage above 1.5volts.
How do you charge a NiMH RC battery?
Normal Charging
The best way to charge a nickel metal hydride battery is to charge at C/10 or below (10% of the rated capacity per hour). So a 100 mAH battery would be charged at 10 mA for 15 hours. This method does not require an end-of-charge sensor and ensures a full charge.
How do you charge a NiMH battery?
Charging Considerations for NiMH Batteries?
- Trickle Charging is the safest method you can charge your battery. To do so, ensure you are charging at the lowest possible rate that will keep your overall charge time BELOW 20 hours and remove your battery at that point.
- Do not overcharge NiMH batteries.
What amp should I charge my RC battery?
As a general rule, you should charge your batteries a current of 1C. So, for a 2200 mAh capacity battery, the charge rate should be 2.2 Amps and for a 1700 mAh capacity battery, the charge rate should be 1.7 Amps.
Should I charge my battery at 2 or 10 amps?
It is best to slow charge the battery. Slow charging rates vary depending on the battery’s type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.
What should a 12V battery read when fully charged?
about 12.6 to 12.8 volts
A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
How much voltage is needed to charge a 12V battery?
A: A 12V car battery can be safely charged over a range of voltages. It needs at least 12.9 volts to charge, but at this voltage the charge rate of an automobile battery is very slow. A car battery can be charged safely at high voltages as long as the battery is not fully charged.
How long should I charge NiMH battery?
NiMH Chemistry
- Rapid Charge: A charger can provide a rate of 0.3-0.5C as it will take 3-6 hours to charge.
- Fast Charge: Charger can be set at 1C charge rate as it can take from 1 hour or more to fully charge.
- Ultra-fast Charge: A charger can have a charge rate of 1C up to 10C.
Can I charge a NiMH battery with a lithium ion charger?
No, you cannot, you should not for your own safe. NiMh and Lithium batteries have different chemistries, different cell voltages and they require different charging methods/algorithms.
Can you over charge a NiMH battery?
Overcharging leads to overheating and damage to the cell resulting in loss of capacity and nickel metal hydride cells are more sensitive to this than NiCds. This means that chargers need to be careful designed to ensure that overcharging does not occur, and users also need to be a little more careful as well.
Does higher mAh battery last longer?
In general, the more mAh and the longer the battery capacity or battery life. A higher number means that the battery can store more energy, so it has a higher capacity. Of course, this also means longer battery life for a given usage.
How many hours does 10000mah last?
If your device draws 1mA (milliamps), then the 10,000mAh battery can last for 10 hours before running out of power. If your device uses 10,000mA (milliamps) then the battery may only last for one hour before running out of power.
How long does a 1600 NiMH battery last?
The capacity is 1600mah which is good for over 1000+ shots if fully charged and used on a stock gun. Mah (milliamp hours) is your capacity — think of it as your gas tank.
