How do you wire batteries together to get a stronger cell battery?
For more voltage, put them in series with each other (+ to - to + to - etc). For more power put them in parallel with each other (+ to + and - to -). The best way for more power is to use a larger power rated battery. Go from an AAA to an A or C or D or for use in an auto use a higher rated car battery.
Can a cell phone battery rated 5.0V 0.6A 800mAh be substituted with a battery rated 4.75V 0.55A 1000mAh SAFELY?
probably not. get the right battery.
How do you charge battery with ac power supply I have a 12 volt dc battery and im trying to charge it with a power supply rated at 0-40 volts 0-5 amps?
You should charge the battery with the proper battery charger. The battery charger should list what types of batteries, voltages, and charge rates (amps) it is compatible with. Make sure this matches the information on the battery to be charged. Using the incorrect battery charger can cause battery explosion, leaking, or fire.
How much power is used by a 12 Vcar battery that draws 0.5 A of current?
Power is simply voltage times amperes, so 12 x 0.5 = 6 (Watts). Actually, if the battery is rated at 12V, it will require a somewhat higher voltage to load it.
How much amp is needed for a 40 watt light bulb?
If that's a continuous load of 40 watts, you need quite a large battery, depending on how long the demand is. Car batteries supply more than 40 watts when running the cars lights when the car's ignition is switched off, so I guess something like a motorcycle battery would suffice.
What Effect does battery capacity on a circuits internal resistance?
Batteries are rated as ampere/hour any circuit that draws power from it effects it. The lower the internal resistance of the circuit the shorter the useful battery life as discharged.
What are some good brands for rechargeable battery rechargers?
Top rated battery chargers include the Alpha Power, Sony Quick Charger, WizardOne Charger-Analyzer, the Energizer Recharge Rapid Charger, and the Duracell GoMobile Charger.
What do amp hr mean on a 12 volt battery?
It is a rating for the capacity of the battery to power a load. A battery rated at 15 amp/hrs has the ability to power a load of 15 amps for 1 hour, or 1 amp for 15 hours, or any combination of the two numbers. Example, 2 amps for 7.5 hours, 3 amps for 5 hours or 5 amps for 3 hours etc.
How much power is used by a 12- Vcar battery that draws 0.5 A of current?
The power used by the car battery can be calculated using the formula P = V x I, where P is power, V is voltage, and I is current. Plugging in the values, we get P = 12 V x 0.5 A = 6 watts. Therefore, a 12V car battery that draws 0.5A of current uses 6 watts of power.
Can you replace a battery that is rated at 4ah with a larger ah battery?
Yes, it mAh or Ah is how long the battery lasts, it does not affect performance.
Why generators are rated at 0.8 lagging power factor?
Rated power factor
What are the ratings and certificates for Reserve Battery - 2011?
Reserve Battery - 2011 is rated/received certificates of: Australia:MA
