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.
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.
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 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.
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.
Why generators are rated at 0.8 lagging power factor?
Rated power factor
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.
What are the ratings and certificates for Reserve Battery - 2011?
Reserve Battery - 2011 is rated/received certificates of: Australia:MA
What is the difference between 1000mAh and 1400mAh batteries?
280mAh :-) , no really, basically it puts out more power. Some devices can handle the extra power, but others can burn up. You take a chance when you use a higher rated battery than what the device was made for.
