Science Experiment - Battery Life
Aim: To find out and collect data on the power life of 2 different branded batteries.
Equipment:
- Multi-meter
- BatteryCare battery
- Alkaline(Sanyo) battery
- Spare Wire
- Sticky tape
- 1.3 Volt electric motor
Method:
1. First take readings of the 2 different batteries power levels using a multi-meter.
2. Attach 1 battery up to the 1.3volt electric motor using some of the spare.
3. Use sticky tape to ensure the contact between the wire and the battery are at there greatest capacity.
4. After 1 hour is over or the battery dies take a reading of its power level using a multi meter.
5. Repeat the above steps with the second battery.
Results:
BatteryCare:
Started off with 1.585 Volts and ran for 21 minutes before it run out of the required amount of power to allow the motor to function. Its final multi-meter reading was 0.572

Alkaline(Sanyo):
Started off with 1.604 Volts and ran for 60 minutes with a result of 1.246 volts. After this period of time the battery was running the motor very poorly. Total loss of 0.358 Volts over a period of 1 hour.
Conclusion:
I bought a normal 1.3 Volt Electric Motor from a hand held fan that ran off 2 double A size batteries.
I first recorded the amount of power in both batteries using a digital multi-meter.
During the experiment the BatteryCare battery was making the motor run high then slow then high then slow and by the end of the experiment it clearly showed that the battery was leaking as it was sticky and the label was soaking. Also the BatteryCare were made from cheap metals as using fingers you can easily squish the battery, yet the alkaline battery is made from good metals,
