Question about Sony Cyber-Shot DSC-S40 Digital Camera

Batteries discharge rapidly and even spontaneously

Got two different sets of rechargeable batteries. Both sets show the same problem - they get discharged very rapidly. When the camera is used, then the batteries get discharged after some 30 shots (!), when not used, then the spontaneous discharge takes about 2 weeks (!). Since the batteries set are each of different type and from a different manufacturer, I believe the prob must be in the camera.

Re: Batteries discharge rapidly and even spontaneously

I wrote the above information (which is not a solution) but have since talked with a Sony tech by phone. He had me reset the settings on the camera. I followed his directions. Guess what? My battery consumtion issue seems to be resolved. I will certainly keep track of battery related data for now until I am sure I am out of the woods. If the problem returns, its back to the drawing board. By the way, my camera turning off after 3-4 minutes is a normal function.  Good luck!

Re: Batteries discharge rapidly and even spontaneously

I have the same problem. I believe the camera is defective since the rapid discharge has ocurred since I bought the camera in June of this year. My sister has the same camera which she bought at least 2 years ago. Her batteries last at least triple the amount of time as mine do and she takes far more pictures that I do. As an experiment, I used her batteries in my camera and they discharged after 30 shots at the most. When the same batteries were recharged and loaded into her camera, the batteries lasted for more than 120 shots. I'm really frustrated. I bought this camera per my sister's recommendation and it cost more than $350. The store has offered to send it back to Sony for a fee but I'm afraid Sony will say I am at fault and not replace or refund.

My Fujifilm FinePix AV100 12MP Digital Camera battery easily gets discharge or Low Battery even the battery is fully charged and new, what do you think the problem might be???

Welcome to FixYa.

First thing we need to verify is what type of battery are you using.

The Capacity of rechargeable Ni-MH batteries may be temporarily reduced when new, after long periods of disuse, or if they are repeatedly recharged before being fully discharged. Capacity can be increased by repeatedly discharging the batteries using the DISCHARGE option and recharging them in a battery charger. Do not use this option with non-rechargeable batteries.

Also possible reason why your battery easily discharge if:

* battery are cold
-warm the battery by placing them in your pocket or other warm place.
* ther is a dirt on the battery terminals
-clean the terminals with soft and dry cloth
* the camera is always on AUTO mode
- choose different shooting mode

I hope this information will help on your issues.
Feel free to send us your comments or suggestion if this solution is helpful.

Shows low battery, even after installing new batteries. will not work.

The best batteries are rechargeable NiMh batteries of the ENELOOP (Sanyo) type.
These batteries have a very, very low discharge. Some other brands have such types too.

This might indeed be the case if you had the batteries for a while, and have recharged them several times. Unfortunately, even rechargeable batteries don't last forever, and need to be replaced. You can actually shorten this life of rechargeable batteries if you don't "discharge", or, "charge" them up correctly when first purchased, strange as that might seem.

Hope this helps. :)

NO PICTURES two: Use the right battery What AA battery should I use for best performance? The following table summarizes how AA batteries perform in different types of use. Type of Use Alkaline NiCd Ni-MH Oxyride Photo Lithium Most economical when taking more than 30 pictures per month Poor Good Good Poor Fair Most economical when taking less than 30 pictures per month Fair Fair Fair Fair Good Heavy use of flash, frequent pictures Poor Good Good Fair Good Heavy use of video Poor Good Good Fair Good Heavy use of Live View Poor Good Good Fair Good Overall battery life Poor Fair Fair Fair Good Low temperature/winter use Poor Good Fair Poor Good Infrequent use (without dock) Fair Fair Fair Fair Good Infrequent use (with dock) Fair Good Good Fair Good Recharge batteries No Yes Yes No No Solution three: Make sure that your batteries are completely charged Follow the steps below for your battery type: Ni-MH rechargeable batteries Ni-MH batteries lose charge, or self-discharge, at a rate of one to two percent per day, whether they are installed in the camera or not. This means that if a battery is fully charged, after several weeks, the battery will be low or dead even if it was not installed in the camera or if it was installed in the camera but no pictures were taken. Ni-MH batteries are best for those who use the camera frequently and recharge often. The amount of charge that Ni-MH batteries can hold gradually decreases because of usage, aging, and lack of maintenance. To maintain your batteries at maximum capacity, "condition" them when they are new or have not been used for over a month. Follow these steps to maintain (condition) your batteries:
  1. Completely discharge the batteries by using the camera normally until it will not operate.
  2. Recharge the batteries.
  3. Do this three or four times.
NiCd rechargeable batteries Nickel-cadmium (NiCd) batteries lose charge or self-discharge at a rate of one percent per day. Store NiCd batteries in a cold place such as the refrigerator or freezer to minimize the loss. To store in a cold place, place the batteries in a tightly sealed container to keep the moisture out. Before using them, warm the batteries to room temperature. The amount of charge that Ni-Cd batteries can hold gradually decreases because of usage, aging, and lack of maintenance. To maintain your batteries at maximum capacity, "condition" them when they are new or have not been used for over a month. Follow these steps to maintain (condition) your batteries:
  1. Completely discharge the batteries by using the camera normally until it will not operate.
  2. Recharge the batteries.
  3. Do this three or four times.
Alkaline, Photo Lithium, and Oxyride non-rechargeable batteries Make sure that the batteries are new and have not been used for anything else. . Solution seven: Try a new set of batteries If you have tried all the solutions described above but your batteries still do not last very long, try a new set of batteries. If the old batteries are damaged, a fresh set of batteries will solve the problem. Batteries can be damaged in the following ways:
  • NiCd and Ni-MH batteries can be damaged by over-charging. After a battery has been recharged, do not try to add additional charge to the battery by sending it through another recharge cycle before using it.
  • Batteries can be damaged by dropping or sudden impacts. Even if there is no apparent external damage, the rechargeable battery could later develop an internal short or leak while in the camera and cause damage.
  • If batteries have become wet, they may short out and will not work properly.

I use rechargeable batteries in my FE-35 and they are constantly showing up as empty. They show as full for about 30 secs and then they are shown as completely empty. It's very frustrating. Has anyone else...

This may not be so much an issue with the camera as much as a problem with the batteries. Since these are type "AA" battery packages, you should attempt to use them in another device - such as a small flashlight or other device that can operate on AA batteries.

If the batteries fail to to power the flashlight (or other test device) for more than 5 - 10 minutes after charging overnight (or as long as directed by the battery charger), the problem is with the batteries. It is very important that the batteries are charged properly. Properly means for for the required amount of time AND in the correct charger. There are different types of battery types: NiMh, NiCad, NiZN, Li-ion, etc. Using the wrong charger to charge the batteries could cause unpredictable results - or create a potentially dangerous condition. Additionally, some battery types develop a "memory" and can be responsible incomplete charging and rapid discharge. This happens if the initial charge is insufficient and the batteries are not completely discharged prior to recharging. It may be possible to recondition these batteries - but this size battery is relatively inexpensive, so replacement might be a better option.

If the batteries are working okay in the test device, then the problem may lie in the camera itself. Test the camera by installing fresh, AA alkaline batteries. If the camera rapidly discharges the alkaline batteries, it's a safe bet that the camera has a problem.

S9500 : rapid battery discharge

Check your focus control on the left side of the camera is not set to "continual focus" CF, as this will constantly adjust focus and run your battery down quickly.

Also NiCd batteries are not very useful -use Nickel Metal Hydride (NiMh) which last longer and don't suffer from memory effects. These batteries don't reach full capacity until after a number of recharge/drain cycles.

Wont turn on

Only use Ni-MH or AA-size alkaline batteries. Do not use Ni-Cd (nickel-cadmium) because the heat emitted can damage the camera.

I would suggest using e2 batteries from Energizer.

In the manual, on page 80 there is a description and procedure for discharging Ni-MH batteries (but NOT regular batteries, so don't do this with regular alkaline batteries) AND do not do this when the external power is connected.

Moving on... The discharging of the batteries procedure should happen when:
  • the batteries last for a short time after being charged normally
  • the batteries have not been used for a long period
  • the batteries are new.
Follow these instructions:
  1. Press the menu/OK button to display the menu on the LCD monitor
  2. Press the "left" or "right" on the pad to select "SET" OPTION and then press "up" or "down" to select "SET-UP".
  3. Press the "MENU/OK" button to dipslay the "SET-UP" screen.
  4. Press "right" or "left" to move to option 5 and then press "up" or "down" to select "DISCHARGE".
  5. Press "right"
  6. Press "left" or "right" to select "OK".
  7. Press the "MENU/OK" button.
The screen changes and discharging begins. When the battery level indicator blinks red and discharging ends, the camera turns off.

Remember to not have the camera external battery plugged in so the battery can discharge on it's own.

Then, at this point, recharge the battery using the external battery charger. This helps to "renew" the battery. This is because Ni-MH batteries will remember the last place where they recharged, and too many times, the memory "bookmark" gets marked to low and has to be reset, done by the recharge.

It may be necessary to repeat these steps multiple times. This effect is not because the batteries are deffective. This is a normal side-effect of Ni-MH. This is the reason the camera comes with a discharge feature.

I the batteries are old and don't function even after performing the discharge procedure as part of the normal operation of the camera (like of the year or two), then the batteries may have reached the end of their service life.

Hope this helps, if so, please rate FixYa! ThankYa!

Drained Batteries

I use professional $70k cameras for work and it's the same type of thing. If you're not using it, take the batteries out. With my A75 I have some energizer 2200mpa rechargeable AA's and the seem to last about a month or so. If I happen to be "cranking" through pictures though (upwards of 300-500) in one sitting, it will suck them dry. The rechargeable batteries last longer than the Alkalines. I was heistant with the rechargeables but for $20 I picked up a 15 minute charger and the 2200mpa AA's, now I recommend them to everyone with a digital camera. Digital cameras eat Alkaline batteries in a hurry.

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
