SOURCE: Energizer CHDC charger suddenly not indicating if charging or not

It sounds like the PC Board which provides the circuitry for the Charger's indicating light is malfuntioning. If you have a DC volt-meter, you can check the Charger's output voltage, and then the Battery voltage to determine if your charger is functioning.

Hint: If the Charger has an output voltage, but the Battery's voltage is less than its rated voltage... it's time for a new battery.

SOURCE: Energizer Digital Camera Battery (ER-D120)-

The battery is either too hot or too cold....if it was just used then give it time to cool down before trying to charge...

If the battery is at room temperature and you are still getting the fault code then the battery is shorted or open internally.

If the battery has an internal fault it is not easily repairable and you should just recycle it and buy a new battery.

Battery Charge at high temperatures and low

a-collection-of-photoshop-business-card-tutorials-and-free-psd-files-300x156.jpg Nickel-metal-hydride is less forgiving than nickel-cadmium, if applied in high and low temperatures. Nickel-metal hydride may not be quick to load below 10 â° C (45 â° F) and can not be slow to load below 0 â° C (32 â° F). Some industrial chargers are designed to adjust the rate to the current temperatures. price sensitivity does not allow the processing temperature sensing charger consumers.
At higher temperatures, the charge acceptance of nickel-based BTP-58A1 batteries is drastically reduced. A HP 530 battery that provides up to 100% when applied at moderate temperature can only accept 70% if charged at 45 â° C (113 â° F) and 45% if charged at 60 â° C (140 â° F). This demonstrates the poor performance of some summer car charger.
Lead-acid is fairly tolerant to extreme temperatures, as we are familiar with our car batteries. Part of this tolerance is accredited to the slowness of the system lead-acid. Some brands Inspiron Mini 9 (all 8.9 series) battery can freeze and low loads, while others say the damage and provide reduced service and a short life.
To improve the performance of lead-acid battery to colder temperatures and avoid thermal runaway during periods of heat, the control voltage limit, at which the INSPIRON 9300 battery is charged, is important. Implementation of this measure can extend the battery life of up to 15%. General guidelines suggest a compensation of approximately 3 mV per cell per degree Celsius. The voltage regulation has a negative coefficient, meaning that the threshold voltage decreases with increasing temperature.
Heat kills DV2000 battery. The hotter the cells, the shorter the life. High temperatures can not always be avoided, especially during fast charging, but efforts must be made to keep this short time. While 45 â° C (113 â° F) is acceptable if kept short, at 50 â° C (122 â° F) and above, the battery starts to suffer. Note that the cells inside the packaging are always a few degrees warmer than the temperature of the body.

I have an Energizer Model CHDC7 battery charger for AA/AAA batteries. I'm not sure how to use it. Specifically, when batteries are inserted and plugged in, it displays flashing green lights over all...

Nickel-Metal Hydride (NiMH) batteries are usually charged in pairs in consumer chargers. The CHDC7 can charge two or four batteries at a time. Their position in the charger is important (see the link at the end of this note). Each battery has a separate pair of green LEDs. There are no other LEDs on this charger. The LEDs light up to show the state of charge. Flashing means it is charging. Solid means it has reached that level of charge (ie, 1 LED = half charged, 2 LEDs = fully charged). The batteries will get warm but not uncomfortably so. After some practice you will be able to tell if they are getting too hot (which may signal a worn-out battery which should then be replaced). Like all rechargeable batteries, NiMH batteries have a finite life (measured in number of times they've been discharged and recharged). IMHO, they should also be used and charged in matched pairs. I mark them when I take them out of the box and keep them paired in use and in charging for maximum life. Yes, the devices that use 3 batteries are a pain to deal with. LOL. All details can be found on this Energiser data sheet:

P.S. The CHDC7 remains open for charging. Closing it for storage is optional but minimizes the space it takes up.

How do i know if there is a problem with my double a rechargeable batteries

Although it would be helpful knowing what kind of rechargeable batteries these are, presuming they are Nickel-metal hydride, you can try putting them in a freezer for several hours and then recharge them. Sometimes this jump starts the electrochemistry.

I've been using Olympus 550 UZ camera for over a year now. I am facing problem with the life of battery though. Tried Energizer and Duracel batteries. 10-15photos and the battery is drained down. Is there...

Switch from alkaline batteries to pre-charged Nickel Metal-hydride (NiMH).
My best experience is with these batteries:
#1. RayoVac (pre-charged)
#2. Kodak (pre-charged)
#3 Energizer (rechargeable)

Find them at WalMart or online

"pre-charged" are new technology rechargeable batteries. They are GREAT! They outlast alkaline at least 15 times per charge.

Well i tried to take a picture and i took it and then it turned off once i took the picture

Sounds like the batteries.

Digital cameras are noteably, very demanding power suckers.
If they don't have brand new batteries, they shut off.

They requre top brand (Energizer or Duracell) batteries, and once they are used for even a short time; they will not be enough either.
(Dont' throw them out though, other less demanding things like Remote controlls will gladly use them for years)

The best bet is to use Rechargeable batteries, or have a $100/month budget for duracells.

Statistics you will need to look for in Rechargeable batteries are:

Type; Nickel Cadmium (Ni-Cd) or Nickel Metal Hydride (NiMH)

The Metal Hydride rechargeable battery is best since it charges faster and retains it charge longer, the old fashioned Nickel Cadmium battery used to be the best, but not any longer.

Rating: 900mAh; 1800mAh; 2200mAh; others not mentioned.

Unimportant note: The mAh means Milli Amphere Hours, which means how much power the battery cell will hold when fully charged. It is measured in Ampheres (Amps) per Hour, or in this case Milliamperes (1/1000 of an amp), but that's not important to know; all rechargeable batteries are rated by this number.

The number of mAh's you want are about 1000 or more,

Generally it's the more mAh's you have the more you can take pictures. Such as 900mAh will get about 50 to 250 pictures, but 1800mAh will get you twice as much.

Last note on Rechargable batteries: Only use a LiMH charger for LiMH batteries, and use a NiCd Charger for NiCd batteries.
If a charger dosn't say what type of batteiries it charges, it's the old fashioned NiCd (Nickel Cadmium) from the 1900's when that was the only type of rechageable battery.

Good luck with your Digital Camera.

Won't charge

2 screws hold the shaver together. The second one is under the trimmer (open your trimmer).

As I am an electronics hobbyist, I am able to unsolder the 2 nicad batteries. It is a bit of a trick to pop this thing apart though, but can be done. See comments from another guy who stated it well...

The batteries are most absolutely 100% replaceable, though I do *not* recommend you try unless you are an electronics hobbyist/electrical engineer/ham radio operator/genius. This requires the ability to work with delicate electronic components, solder, and desolder.

In case you are not familiar, "planned obsolescence" is all the rage these days. The definition is quite simple. Literally, it means that major consumer electronics companies plan products to fail in a given amount of time, to increase their profits. Lovely, huh? Modern battery chemistry for consumer grade rechargeables is Nickel Metal Hydride. These batteries do *not* have a memory which affects charge cycles. The older technology is Nickel Cadmium, which is dangerous for the environment and develops a memory, impacting the amount of charge the cells can hold over time. Philips intentionally continues to use Nickel Cadmium cells instead of the better Nickel Metal Hydride. They also make it extremely difficult to replace the cells; that is, they build these brushes with "planned obselescence" in mind.

If you are extremely careful, you may try to replace your batteries. When your brush no longer chargers to your satisfaction, VERY gently pry open the handle with a flat-bladed screwdriver, after running down the battery. Once it is open, you will see two "AA" Nickel Cadmium cells soldered into place. This is when you find your ham radio operator, electronics hobbyist, electrical engineer, or genius friend. Or, if you are one of the above...

Carefully remove the existing Ni-Cad cells, and recycle them properly. Find some high capacity Sanyo Nickel Metal Hydride cells, and put them in instead. Reseal the whole deal with epoxy, and see how it turns out.

Remember, in doing this, if you mess up, you had nothing to lose. Let me add here that if your dog turns in a squirrel or your ear turns to pudding in attempting this, I am *not* responsible!

Batteries always low

If you're using regular alkaline batteries that?s fairly common. If you want longer life most people purchase rechargeable nickel-metal hydride batteries and a charger. Depending on the camera you?ll get 40 or more flash images out of a charging. I have two sets, one in the camera and one in the charger. Expect to pay about $5 to $10 for a set of four and around $10 or $20 for a charger, make sure its for nickel-metal hydride batteries and not the old style nickel-cadmium. Good luck and don?t forget to rate this post.
