Suitable battery for canon A 1000 IS?

Answer 1

Canon A1000IS is AA battery camera. AA battery camera is the most suitable for High capacity NIMH battery.Because,the working current of camera is very large, nearly 1000mah.For examples SONY DSC-P92,Maximum working current can reach 1350mah.This kind of electric appliance is the higher requirement to the Load capacity of battery. NIMH battery has better load capacity than Alkaline battery. So AA battery camera used NIMH battery can take more photos.

I have done the experiment and collect many data from different people different cameras. I can draw the following general conclusions. If you have interests,you also can go to check.

If the camera can takes more than 10 photos with two AA alkaline batteries, the camera can flash Photography more than 1000 pieces with two AA 2300MAH NIMH batteries.

If the camera can takes more than 200 photos with four AA alkaline batteries, the camera can flash photography more than 1500 pieces with four AA 2300MAH NIMH batteries.

And the data of the camera with four batteries is more accurate than the one with two batteries.

The following series FUJI S2500,FUJIS2600,FUJIS2900,CANON S2IS,Nikon L100,L110,L120 both can reach the good effect.

But the charge of NIMH battery is really a problem. Now,NIMH battery changer usually use constant voltage source. The way always cannot charge sufficient NIMH battery fully. Because the charging current of the constant voltage source can change. It detects the characteristic of battery to determine sufficient. But when the NIMH battery is charged sufficient, the characteristic is different. Even the same battery can produces different characteristic when it is new and old time.So it is difficult to charge sufficient battery with constant voltage source.

The constant current cource is good way to charge NIMH battery.The charging current of constant current source is constant.So if we know the capacity of battery and charging current,we can calculate the time of charge.We control the time of charge,We can control the total input power.So any battery can be charged sufficient.

If 2300MAH NIMH battery can be charged sufficient, you can flash photograph more than 1000 pieces.

Now, constant current source battery charger is vey rare. The best is in shanghai china,call "tianyuan",in china called"天元".The company is specializing in the study of variable constant current technology enterprises.

"tianyuan" battery charger has 4 grades of constant current source,from 300MA-150MA-70MA-35MA,which can charge 150mah-3000mah range NICD,NIMH battery,the charging current is not charge according to number of battery,and 1-15 hours digital timing control which the precision is very high.

"tianyuan" also writes some importmant articles about battery and battery charger.If you read these articles,you will konw more knowledge about this area.

Above the camera shot of data is just from the shanghai tianyuan.

Finally, I am sorry ,my English is not very good. If something you can't understand,you can e-mail to me.I will do my best to answer you.
