Rechargeable batteries, especially the Nickel-Cadmium type (NiCad) suffer from a phenomenon known as "memory". If they are routinely discharged only partially then put back on charge they will eventually "remember" this duty cycle and work only a few minutes before needing to be recharged. This can sometimes be reversed, but doing so is not always easy. The newer NiMh (Nickel Metal-Hydride) batteries have mostly overcome this problem, but shallow-cycling your rechargeable batteries is still not a good idea. It's also a possibility that your batteries are worn out and need to be replaced. Rechargeable batteries can only be recharged a certain number of times before they go bad. With top quality batteries and a proper charge/discharge cycle, you can occasionally get up to 1000 charge/discharge cycles out of them. With so much of this stuff coming from China these days it is becoming increasingly difficult to find really good rechargeable batteries.

If these are lead-acid batteries, then the symptom you describe indicates that replacement is likely needed.

Know the Disadvantages of Each Two Way Radio Battery?


Li-ion Lithium ion batteries amount conspicuously added than added two way radio batteries, and at the aforementioned time they are beneath abiding and added chemically volatile. Also, Li-ion batteries crave their own chargers (NiCd and NiMH batteries can generally use the aforementioned charger) and at abounding ability can irreversibly lose amid 5-20% of their accumulator accommodation annually.

NiCd The capital disadvantage of a nickel cadmium array is its susceptibility to "memory effect," acceptation that the array gradually loses its accommodation for abounding recharging if it is again recharged afore its accommodation has been absolutely drained. Because of this, nickel-based batteries (both NiCd and NiMH) are almost aerial maintenance. Also, the cadmium in NiCd batteries is toxic.

Worx cordless drill battery pack wont hold a charge at all its about 3 years old


If it is a Nickel cadmium battery, it has probably developed "memory" - that means it becomes used to partial discharge and the capacity has gone down.

You can partially revive it by deep cycling a couple of times, like this:

1) run the drill till it stops (can tape the trigger on, if necessary)

2) recharge fully

Repeat steps 1 and 2 , after that the battery should hold the charge a bit better. These rechargeable batteries do wear out eventually. Lithium Ion batteries are better than the Nickel Cadmium.

I can't seem to get the correct batteries for my Texas Instruments TI-84 Plus Calculator...can any AAA 1.5v battery use in it? I tried some duracell of that same type and they didn't work


All the AAA batteries whether non-rechargeable alkaline (Duracell, Energizer, Rayovac, Varta, Maxell, Panasonic, Sony, Sanyo, etc) will do. Each of these types of batteries has a voltage of 1.5V
You can also use rechargeable NiCd (Nickel-Cadmium) or NiMH (Nickel-Metal Hydride) 1.2V AAA. However TI Instruments say that under no circumstances should one use rechargeable batteries.

The trivial possible reasons why the the Duracell did not work are:
  1. The lot was depleted.--Replace with fresh ones
  2. The electrical terminals may be broken or dirty or corroded by a previous acid leak.---Clean the terminal even if they appear shiny. The eraser tip of a pencil should be good to rub away any dirt.
  3. You did not place them correctly: Wrong polarity. This is a very common mistake (I know from my own experience).

Need to replace battery back-up pack. Have any


Oh wow. You have an old timer there. I think they used a rechargeable 3.6Volt pack so you should be able to use any old rechargeable nickel cadmium or nickel metal hydride 3,6V battery such as out of a cordless phone. try a local electronics shop.

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.

Do not use "ordinary" alkaline batteries. Try using rechargeable batteries like nickel cadmium or nickel metal hydride.
