How long does a rechargeable battery normally take to recharge?

Battery charging time is determined by capacity, but not voltage.

Charging current generally choose 10% of the capacity of the 10 hours rate, the maximum current is not more than 30% of the rated capacity value, if the charging current is too large, the storage battery easy fever, plate bending, fall off, rupture, short circuit that caused the explosion, burning and other accidents.

Charging time (hours) = rechargeable battery capacity (Ah)/charging current (A) * 1.5 coefficient.

For example: suppose that the battery is 30 ah, is: 30/3 * 1.5 = 15 (h)

Generally recommended charging time is more than 4 hours, 12 hours following is advisable.According to the brand, battery types and all materials are different and different, please according to the instruction to use.

Rechargeable batteries, is charging limited number of rechargeable batteries, use with the charger.Usually sold on the market, 5, 7 but there are no. 1.Rechargeable batteries are the benefits of economy, environmental protection, power, suitable for high power, long time use of electrical appliances (such as the walkman, electric toys, etc.).

Rechargeable battery type:

Nickel cadmium (Ni - Cd)

Voltage: 1.2 V for life: 500 times

Discharge temperature: - 20 degrees to 60 degrees

Charge temperature for: 0 degrees to 45 degrees

Nickel metal hydride (Ni - MH)

Voltage: 1.2 V

Life is: 1000 times

Discharge temperature: - 10 degrees to 45 degrees

Charge temperature for: 10 ~ 45 degrees

Note: the current domestic battery 5 highest capacity is 3000 mAh.

Lithium ion (Li - lon)

Voltage: 3.6 V

Life is: 500 times

Discharge temperature: - 20 degrees to 60 degrees

Charge temperature for: 0 degrees to 45 degrees

Note: the weight is 30% ~ 40% lighter than Ni-Mh batteries, nickel-metal hydride batteries by more than 60% higher than that of capacity.But not resistance to overcharge, if temperature is too high and damage caused by overcharge will structure caused by the explosion.

Lithium polymer

Voltage: 3.7 V

Life is: discharge temperature for 500 times: - 20 degrees to 60 degrees

Charge temperature for: 0 degrees to 45 degrees

Remark:Lithium electricity improved type, no battery fluid, and use polymer electrolyte, can make all kinds of shapes, than lithium battery stability.

Lead-acid battery

Voltage: 12 v

Life is: 200 ~ 300 times

The discharge temperature is: 0 ~ 45 degrees

Charge temperature for: 0 degrees to 45 degrees

Note: it is general vehicle battery (it is 6 2 v series into 12 v), free water battery life up to 10 years, but the volume and capacity is the biggest of all.

"Standard charge 70 ma to be 14 hours" said you good to charge the battery with 70 ma charger takes 14 hours {if your charger current is 100 ma of the battery you need (70 * 14) / 100 = 9.8 hours)}.

Great "700 mAh says" you can put the current 700 ma to devolve electricity an hour (in fact he is the capacity of your battery, you use the battery capacity is too small, generally speaking, there are 1800 mAh and 2000 mAh or 2500 mAh capacity of the battery;Two and a half of 700 mAh = 700 mAh section capacity. But the price corresponding to high)

And the first three times in the battery to charge more than 12 hours to good;Slowly it's good that it use method and cell phone battery.

Hope you the best in using high capacity battery, the battery can be used in razor and electronic alarm clock on their consumption capacity is relatively small.
