Question about Canon PowerShot A520 Digital Camera

3 Answers

Battery drain My 520 has become hypersensitive to "low" batteries. Didn't use to be. Rechargeable or not, I will get 'replace battery' message on batteries that test way in the green on my tester. I cleaned the camera contacts with alcohol. New batteries will make it work, but fail way to soon ...usually at the perfect 'kodak moment'. Is it worth having repaired or ???

    I gave up on the rechargeables (have been using the 2700 mah) and got the more expensive lithium AA's (non-rechargeable). They're worth the cost.

    My 520 turns off as soon as it flashes for a picture, sometimes with the change the batteries message and sometimes not. Sometimes it doesnt even flash. It turns off with the lens still out: the power light just goes off. I can still look at previous pictures and it seems fine, but when I try to take any it doesnt work. The batteries are brand new and non rechargeable. I've tried a few different brands. Does anyone know whats causing this? Can it be fixed, and if so, is it worth it?

I have the same problem and wrote to Canon. It's been a month but I am hopeful they will respond.

I have the Canon A540, almost a clone of your camera, and it doesn't **** batteries at all. I thought it did at first, as a matter of fact, I almost returned it. But then, I stopped using my old rechargeable batteries, and started using the newer, higher mAH batteries. Try using a rechargeable battery that is 2500-2700 mAH or higher. I noticed that the older rechargeable batteries I was using were only 650 mAH, and it really made a difference.

Exactly the same. Used to be fine. It has only just started doing this.

Toc not available


Problem solved: Downloaded service manual and after studying it for awhile found the fault.
1. On power up in "timer record" mode the 520 proceeds to record selected input until the timer shuts the power to the 520 off.
2. TOC info is stored in memory along with error code history.
3. On power up TOC is read from memory and written to disk and second recording started.
4. Found BT451 had failed (causing loss of 2 above) as soon as the power is removed from the 520.
5. Replaced BT451
BT451 1-528-739-11 BATTERY, LITHIUM (SECONDARY)
(Sanyo ML2016-HJ1 40mA/h 3v rechargeable is suitable replacement) shop around as prices vary

I actually fitted a Lithium battery removed from an old satnav I had lying around! bit of overkill really as it 1400mA/h

Note a faulty BT451 can cause quite a few other problems as well so it's worth checking out and replacing if low or not holding it's charge...........

Dead battery


Be sure to charge your batteries fully before installing them. If the batteries are non-rechargeable, dispose of the old batteries properly, and then replace them.
Rechargeable batteries have a limited number of charge/discharge cycles before they become exhausted. If your rechargeable batteries are dead after a full charge cycle, they may also need to be replaced.

Your battery storage capacity is low


When you see this on your screen it is best that you replace the battery with a correct one. The message means that the cell that are in the battery are almost completely drained and are becoming faulty, this is normal in all batteries.

The low battery message beaps on my phone every couple of days even though I know it has been sitting in the charger securely.Do I need a new rechargeable battery?


Usually this has to do with cells in the rechargeable batteries dying and then not allowing them to hold a charge as long usually requiring you to replace batteries because over time it will get worse and the talk time allowed or off the charger will become less and less

Battery life


The rechargeables are only meant to last a couple years maximum (pretty good that you got three out of them). Also rechargeable NiMH's have approximately 5 times the power of standard alkaline batteries. Alkaline batteries should only be used in emergencies in digital cameras as they will only last for a short while before they are drained (as you've discovered).

The obvious solution is that it's time to consider purchasing a new set of rechargeable NiMH batteries. Look on the package for a power rating of at least 2,500 mah. Avoid batteries that do not list the power rating as they are generally inferior batteries.

Rechargeable batterie won't work in my Camera.


Not sure what camera you have, but some cameras require a very steady power supply voltage. Also not sure how old your rechargeable batteries are either, but batteries (alkaline and rechargeable decay over time. With the rechargeable ones, the more you use it, the less it can charge to full capacity over time. For example, if your rechargeable battery is supposed to charge up to 1.5V, over a period of a year with constant recharges, you can test with a volt meter and see that it never really goes back up to 1.5V, but more like 1.48V, 1.45V or maybe even 1.4V.

Depending on the camera or other item you use rechargeable batteries on, it can adapt to low voltages with special circuitry inside (but only to a certain limit, when a battery is old, it is old).

You can try buying a new set of rechargeable batteries and use it few times and see if this fixes the issue. If not, your camera may be faulty and just draining the battery (not too likely, but it happens).

When should I replace my backup battery?


The back up battery should be replaced immediately upon seeing the message "Backup Battery Very Low - Your back up battery is very low or missing. Data loss may result from failure to replace the battery very soon. Consult the manufacturer's instructions for directions on replacing or charging the backup battery." Warning: It is important to note that the back up battery in the MobilePro 900 is not rechargeable, thus, to prevent data loss, it is important to change the back up battery immediately when this message is displayed.

What is the difference between the available AA battery chemistries?


AA batteries are available in four basic varieties: Alkaline Nickel-Metal Hydride (NiMH) Nickel-Cadmium (NiCad) Photo Lithium (Li-FeS2) Alkaline and photo lithium are non-rechargeable, while NiMH and NiCad are rechargeable. Each has advantages and disadvantages. Non-Rechargeable vs. Rechargeable: Rechargeable batteries are desirable from an environmental standpoint because they are reusable. Self-discharge refers to the fact that batteries lose energy when unused and even when not in a camera or other device. Rechargeable batteries tend to have relatively high self-discharge rates, approximately 1-2% per day for nickel-based batteries. Non-rechargeable batteries generally have very long shelf lives and extremely slow self-discharge rates. This makes non-rechargeable batteries a better choice for infrequent usage. Non-rechargeable batteries are available fully charged in stores all over the world, which makes them a convenient choice for travelers or customers who have dead rechargeable batteries and no time to recharge. Photo Lithium Batteries (Li-FeS2) (non-rechargeable): Photo lithium batteries will yield the longest battery life of any AA battery, surpassing NiMH by 50-100% and surpassing alkaline by 100-500%, depending on the load. While they are more expensive than alkaline batteries, their additional energy capacity makes the cost the same or less per shot than alkaline batteries. Nickel-Metal Hydride Batteries (NiMH) (rechargeable): NiMH batteries are the lowest cost overall solution for users that take a lot of pictures (more than the equivalent of a roll of film per month) or use a lot of high-power features. The largest disadvantage to NiMH batteries is their fast self-discharge rate of 1-2% per day whether the batteries are in a camera or not. NOTE: NiMH batteries need to be completely charged and discharged a few times when new to achieve their full capacity. Rechargeable batteries will eventually fail. If you have been getting acceptable battery life and then see a decrease in life, either quickly or slowly over time, a worn-out battery may be the cause. Storing or charging the batteries in high temperature conditions will accelerate this potential failure. Alkaline Batteries (non-rechargeable): Although the cheapest and easiest to find, alkaline batteries yield the worst performance of all the chemistries in a digital camera. They lose capacity at high power drains and at low temperatures. Skiers and other winter outdoor enthusiasts may find them unsatisfactory. Alkaline batteries are frequently available in two types: High drain (ultra, titanium, maximum etc.) Regular The high drain versions are a premium product designed to operate better under heavy loads than the standard product. However, there is a trend of major brands to increase the performance of their standard battery to b
