Is it possible to charge a NiMH battery without a charger? Yes, it is! All you need is a power source that supplies enough current (in milliamps) to charge the battery. The voltage does not need to be exact but should be close
A fully charged AA NiMH rechargeable battery should measure approximately 1.4 to 1.48 volts. You can use a multimeter to test the voltage once you believe the batteries are fully charged. (Nickel-Cadmium) batteries ensures safety and efficiency. Chargers designed for these battery types regulate voltage and current during charging
The maximum current depends very much on the chemistry of the battery. The capacity of the three main (no Lithium) batteries is approximately: Zinc-Carbon: 540mAh; Alkaline: ~1000mAh; NiMH: ~900mAh; The current
To do this, you have to divide the battery capacity (mAh) by the charger''s charge current (mA), then multiply that value by 1.25. As a result, you''ll get an approximate charge time in hours. Let''s illustrate this with the following
For example, the earlier battery might product 3300 mah at 0.5 C draw instead of 3000 at 1 C. C rates are also used for charging, which denotes their max charging speed. So in our example, the 3000 mah battery with a 0.2 C charge rate should be charged at 600 mah at most.
If the current is too high it will blow the fuse on the multimeter, or blow up the battery. Wikipedia says the Energiser AA battery has an internal resistance of about 0.15R at room temperature. This gives around 10A current. However, the internal resistance of the multimeter may now have an effect, reducing the current.
You should look in the datasheet of that AA battery and check the discharge curves. That gives you an indication. Note that the highest discharge current that is
How many hours should you charge a dead battery? Charging a dead battery might take longer initially, but it''s recommended to follow the manufacturer''s guidelines for charging time.
