Re: Why does my battery gauge seem inaccurate?

In a variable-load high power device such as a digital camera, the battery level indicator gives a prediction of remaining battery life, based on current rate of consumption. Since different operations consume different amounts of power, the battery gauge may appear inaccurate if changing the operations being performed by the camera, which changes the rate of power consumption.

Why does my camera feel hot and says batteries are too low to take pictures (when I put brand new batteries in the camera).


Are these rechargeable batteries or disposable?

The following link describes how to choose the right AA battery for your HP Camera.

Also this is the reason why your batteries say you are low (link is to the HP support page)

"
The battery gauge predicts the remaining battery life, based on the current rate of use. Since digital camera operations such as focusing and using the strobe use battery power at different rates, the battery gauge may seem inaccurate until it adjusts to the new rate of power use. In addition, after changing settings or replacing the batteries, sometimes the camera takes a few minutes to determine how much charge is remaining in a battery. During that time, the battery gauge may not be accurate."

How can i find the battery indicator for the Nikon coolpix s3000 on the display? P.S. page 22 from the manual doesn't help! Thanks,


Greetings - The indicator that is displayed on page 22 of the manual is the only battery indicator in the camera. There is no real time "gauge" of battery status.

As indicated, there is only battery charged (no display), battery low indicator and battery exhausted indicator. You'll find very few (if any) consumer grade point and shoot cameras with that level of monitoring.

Regards and thanks for using Fix Ya.

How do i discharge a new camera battery sanyo vpc-t1284


hi anna ... you probably dont want to do that (discharge the battery) .. depending on the battery chemistry, you cant gain anything and can damage the battery ... for long term storage, lithium batteries like about 70% charge and dont like any complete discharge .. in fact better chargers will refuse to charge the Li battery once the cell voltage goes below a threshold .. when your lithium battery shows dead it is actually still higher than that minimum voltage.. once the cell is below that critical value then conductive bridges start to form inside the battery, that can cause battery overheating and possible explosion during subsequent charging .. so lithium batteries want to stay at least partially charged .. ... NiMH batteries can be fully discharged but that doesnt gain you anything .. they have no "memory effect" .. and deap cycling doesnt improve performance .. normal use cycling of a new battery may increase its capacity slightly as it "breaks in" but deap discharge is not needed or recommended .. for long term storage they want to be in an initial state of fully charged .... in NiCd there is thought to be a "memory effect" which is actually an overcharging effect ... those cells can sometimes benifit from a few deap cycles (conditioning) to erase the effects of over charging, but NiMH and lithium have mostly replaced NiCd in anything less than several years old (since Cd is toxic) .. ... there is only one case where lithium batteries are purposly discharged ... thats on some laptops or other equipment that use relitively large batteries ... but thats not for the battery its to reset the "power remaining meter" in the laptop .. that is a calculated value that tries to measure discharge time vs charge time to guess at what state the battery is in .. it can eventually become inaccurate due to accumulated errors .. discharging then charging the battery will reset that to a new starting point .. so purposly discharging LiON and NiMH batteries is not a good idea and doesn't .improve anything ... there are a lot of people that think it does but thats just habit left over from the NiCd days ... even some manufacturers of electronic stuff still believe that, but you can easily look at the battery manufacturers site to get their view .. you will find that the age old custom/habit of battery cycling is wrong unless you are still using the old NiCd cells ....

Can't Find Battery.


The camera itself doesn't have a battery. If you have a light meter in the finder however, then the battery for it is in the finder itself. Press the button the back on the left side while at the same time, push the lever over on the finder. That will release the viewfinder.

Look underneath and you will see the battery cap. Unscrew that and you'll see the compartment. If it is an old FTn finder, then it will likely take the mercury batteries that are about 1.35V. They don't sell those anymore as mercury is illegal in consumer batteries, but if you do a search on eBay for 1.35V WEIN cells you should be able to track down replacement batteries.

You could put Duracell PX625 batteries in, but they ar 1.5V and thus will give inaccurate meter readings.

Camera not staying on


The 3.3v is for a charger. If you camera has rechargeable batteries in it, thats where that goes.

Samsung.com has them available on their website.

You could inspect the battery contact to see if their getting a connection. sometimes they get bent, corroded, or oxided. You can try cleaning them up.
