Today I will introduce you to the knowledge about the charging time of nickel-metal hydride batteries. I hope to help you. Through the following knowledge, you can better understand the knowledge about the charging time of nickel-metal hydride batteries. I hope you can read it well. Relevant content, enrich their knowledge treasure trove. Next, I will explain the relevant knowledge for everyone.
NiMH battery charging time
Neither nickel-metal hydride batteries nor lithium batteries can withstand overcharging. Therefore, the nickel-metal hydride battery is charged with a constant current in the PICK CUT control mode. When the charging voltage reaches the highest level, it is the best way to stop charging. The lithium battery is best charged with a constant current and a constant voltage. If the nickel-cadmium battery charger-DV control method is used for charging, it will affect the service life of the nickel-hydrogen battery and the lithium battery.
Scientific charging methods can extend the service life of NiMH batteries.
Under normal circumstances, the new nickel-metal hydride battery has only a small amount of power, after the purchase must be charged before use.
However, if the battery has a short delivery time and sufficient power, it is recommended to use it before charging. New nickel-metal hydride batteries generally need to be charged and used 3-4 times before performance can be maximized.
Although the memory effect of nickel-metal hydride batteries is small, it is best to recharge each time you use it, and it is fully charged at one time. Do not charge it for a while and then recharge it. This is an important point of "prolonging life".
If it is an old-fashioned constant current charger, it is necessary to control the charging time according to the size of the charging current. Generally, according to: battery capacity (mAh) / charging current (ma), calculate the charging time, and then multiply by 1.2, it is the actual charging time. At present, the most used is the intelligent charger. This kind of charger will automatically jump to the "trickle charge" state when the battery is full, then the charging current becomes very small, and there will be no overcharging. It is usually enough to charge for one night (a dozen hours). When buying a charger, don't be greedy for "fast", that is, the charging current should not be too large (charging time is very short). If the charging current is large, the battery will generate severe heat, which is very bad for the battery. mAh means milliampere hours, 2300mAh means that the current of the appliance is 2300mA. Your battery can be used for one hour when fully charged. The instructions say that the battery will be fully charged in 23 hours, indicating that the charger's charging current is 100mA. Change to a 1000mA charger, charging for 2.3 hours is sufficient, of course, charging too fast is not good for the battery.
When charging, pay attention to the heat dissipation around the charger. Keep the battery clean when not in use, especially the contacts at both ends, and wipe with a soft dry cloth if necessary. If not used for a long time, remove the battery from the battery compartment and place it in a dry environment.
The specific charging time is better according to the manufacturer's instructions, because this is generally the best result of the manufacturer's own product test, but if the 2500MA battery is slow to charge, it is really time-consuming, so it is best to buy a The fast and slow conversion charger, so that you can use fast charging when you are in a hurry, of course, it has an impact on the battery life. But personally, I have never waited until the battery has reached the theoretical life before replacing it with a fast charge or a slow charge, because no matter how you charge it, the performance of the battery will decline at a certain stage. Performance will make you unbearable and too delays, so I still recommend using fast charging to save time. After all, if you use it frequently, you will need more chargers unless you use less.
NiMH batteries will enter a "sleep" state after being stored for several months, and the battery life will be greatly reduced. If the nickel-metal hydride battery has been left for a long time, it is recommended to charge it with slow charge first. Generally, the voltage of a nickel-metal hydride battery is below 1.2V before charging, and the normal voltage after charging is about 1.4V. This can be used to determine whether the battery is fully charged.
The above is the knowledge about the charging time of the nickel-metal hydride battery that I explain to you. I hope it will be of great help to you, and you can understand the charging time of the nickel-metal hydride battery more deeply. We must have a diligent and hard-working mind, use knowledge to enrich our lives, and everyone who has good knowledge should share it well!
