Battery light blinking red when plugged into charger. I have already bought a replacement battery for this camera at my own cost. Every year this happens. I would either like a new battery (not at my cost) or a camera replacement that doesn't run through batteries once a year. I have had a cheaper Canon camera for over 5 years and this hasn't happened once yet...is there a problem with the Casio Exilim Z75 models that is not being publicized? Thanks in advance.

Occasionally, the charger might show blinking red right to indicate bad batteries. ... This indicates that the battery already have a full charge. If charging is needed, briefly drain the batteries before trying again. If the light blinks red in about 90 seconds after battery insertion, then the battery voltage is too low.

A completed discharged battery yields a solid red light. A blinking red light means the battery has not yet received enough of a charge to operate the phone. You need to leave it on the charger longer, perhaps a half hour or more, for this blinking to cease.

Hi Linda.
not sure if this will help you out,i found this on the internet.
Battery Charger Troubleshooter
When there is a battery failure, there is a possibility it was caused by a bad battery charger. When the charger is only plugged into the wall, it should show a green light. If there is no light showing, confirm that the outlet is good. If the outlet is good, it is very possible that the issue is with the battery charger, not the battery.
If the charger is plugged into the battery only, it should show a green light. (If you have purchased a new charger within the last year, you will not get a green light if the charger is only plugged into the battery. You will get a green light however if the wall charger is just plugged into the wall and not plugged into the wiring harness) If it does not show a green light, it is likely that the charger is not making contact with the battery. The most likely reason for this is a faulty fuse on the wiring harness. This fuse is a 2-amp automotive fuse, and it should be replaced with a 2 or 3-amp fuse available anywhere that sells auto parts. The fuse can blow out if there is a short in the charging system, or if the plug-in end of the wiring harness comes in contact with a battery terminal.
When the charger is plugged into both an electrical outlet and the battery, there should be a red light showing on the charger. A red light showing indicates that the charger is in contact with the battery and is actively charging the battery. Once the battery has reached a voltage level that is considered "fully charged" the red light changes to green. If after 24 hours the light has not changed to green there is no cause for alarm! Remember that when the light is red, the battery is being charged, and you will be able to use your system. After 24 hours or so, your battery is as charged as it is going to get, and if the light is still showing red you should disconnect the charger and go fishing. Replacement chargers and parts can be purchased directly from MarCum's website.
If you are really concerned about your battery, consider getting a basic volt meter to check the voltage of your battery. They can be bought for less than 20 dollars and will show you exactly what the voltage level of your battery is. If after 24 hours of charging your battery should have at least 12 volts (ideally 13-14 volts) and as long as it is over 12 volts it will work. If it is not at or above 12 volts you should consider replacing the battery. If your unit starts to malfunction while you are fishing, it would not come as a surprise that the voltage has dropped down to 11 volts or lower.
If the charger is plugged into the wall and battery, and you get a blinking light on the charger, it is very likely that the battery is faulty and should be replaced.
Batteries are an expendable item, and must be replaced periodically. Any store that sells ice fishing electronics will stock suitable batteries. You can also buy them at a specialty battery store, or by ordering one from our website.The batteries that you should use are the "Sealed Lead Acid" variety, they are 12 volts, and range from 7 to 9 amps. The more amps the battery has the longer it will run on a full charge. Your MarCum unit can be powered off of any battery that is 12 volts, even a large automotive or deep cycle batteries will work.

battery charger is blinking geen Google Search

please see the commentary. God bless you

• 
  The majority of laptops will display a solid green, blue or purple battery light to indicate that the battery is fully charged. Most manufacturers indicate that a laptop is in the process of charging by displaying a solid or blinking green, orange, blue or purple light. If your battery indicator light is green, blue or purple, the battery is probably functional, regardless of whether the light is blinking. If the light is solid orange, the laptop is probably in the process of charging.

  Many battery manufacturers use rapidly blinking lights to indicate that a battery's charge level is low. In general, a laptop will rapidly blink orange or red when its charge drops below a certain level until the computer is plugged into a power outlet and charged. If your laptop's battery indicator continues to blink rapidly in orange or red or if it remains red even when it is plugged into the charger, it indicates a problem with your battery or the charger.

The battery is worn out - replace it.

I really don't have any idea as to what you're talking about here other than a battery and maybe a charger. Seems as if you're saying that you have a 12 volt 1.5 amp automatic battery charger connected to a 12 volt, 8.5amph battery but the red light on your charger is blinking. The blinking red light indicates that the charger is not seeing a proper connection such as crossed polarity connection or simply a poor connection. You say that the battery voltage has dropped from 12.5 volts to 9.1 volts with the charger connected. If this is the case, the battery is badly discharged and the charger is not charging the battery for some reason. The charger may be bad but check the connections to make certain they are correct and good. If they are, I'd replace the charger.

Good luck

I've had this problem just since the last software upgrade. New charger, cable & battery haven't solved it.

As you know, solid red on your charger means that the battery is fully charged and the BLINKING red light means the battery is charging. Unless the light is blinking irradically everything is working the way it is supposed to. If the light is blinking irradically, the battery may just be too hot or too cold to charge ( like when you are driving many lags and your battery dies) and in this case simply wait 15 minutes to charge. If you get a fast blinking light still, the problem probably is with the battery.
