SOURCE: how do I discharge a battery

Why do you want to discharge. Lithium Ion batteries do not have a memory, though they do require a few charge cycles to reach full capacity. In this case, discharge in camera under normal usage.

Another possibility is if you got a very good deal on the internet for a battery, say 50% off, chances are the date code for this battery, even if it was bubble packaged, had expired. Lithium batteries have about a year shelf life before they begin to fail to completely take a charge. Retailers know this and dump them onto the 'gray' market. Another possibility is if you got a very good deal on a charger for your batteries. Lithium batteries are much more complicated to charge and a cheap charger can hurt them more easily than a cheap charge can hurt a nicad or nimh.

SOURCE: My camera stops working but the battery showed full.

Those are the symptoms of a battery that has been charged many times or has been allowed to completely discharge once or twice. Try some new ones.

SOURCE: I'm getting a 'built in memory full' message even

Good day,

It sound like you need to format the internal memory of you camera.
Here is how to do so:

  1. Make sure all the photos that you want are already stored on your computer.
  2. Remove the SD Card.
  3. In the Setup Menu locate Format. (I think it is third to last in the menu screen if you scroll down)
  4. Select YES and follow the instructions.
  5. The format might take a few minutes.
  6. When the format is completed try and take some photos to see if the error has been fixed.

Please let me know if this information was helpful!

Kind Regards

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.

Pictures are misty if we take them in the sunlight & the battery power becomes lower quickly even if it is charged full.


You should know that if take pictures against the sunlight it will be misty. About the batteries, if those are NiCad batteries, it has a problem called memory effect. If you recharge the batteries before it's completely empty, the next time the battery shows it needs recharge when it reaches that level. So recharge the batteries only when they are fully empty. You will have to replace the battery now.

Kodak Z1085 IS - drains battery even when camera is not on


the camera takes 1.5v to operate it
anything less the camera will shut down
recharge batteries are only 1.4v so at full
recharge it won't last long
The best batteries are litheum that have the right
volts and capacity to keep the camera going.
try turning or the camera stablizer setting...
might save your battery power.

Recharge your batteries for AT LEAST 15 hours, even if your charger's light indicates full charge. You should get at least 200 pics from a charge.

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
