Good morning! I have a question about the BlackWeb portable battery 9000 mAh. It does not seem to be taking a charge.

Batteries do wear out and can die. Their longevity can be increased with proper care and charge/discharge cycles but no matter what, the chemicals will erode rendering the battery fubar. Needs replacement. After replacement I would read up on the characteristics of the specific type of battery (ni cad, nimh, lithium, lead acid, etc) and use the procedures best suited for max life for the battery. Example - ni cads like to be fully discharged for best charging, etc.

Norelco 7240 battery

I have a shaver of that type too and when my father's shaver and mine went dead I put NMH type batteries in them. Now these items are made with Ni Cads but they are old design type batteries. The charging of these batteries have to be managed but being the readout on mine tells you when it is full the problem is not such a big one. Just do not leave plugged in for days. Nickel Metal Hydride batteries can have twice the capacity of the Ni Cads and also they have no memory effect.
I would get some premium batteries from Tenergy and solder them into the unit and see what happens. I think they have 2 AH batteries in AA size now and almost that in AAA types.

I need ni-cad battery specifications for Acoustic Research AW-721 headphones. I bought replacement ni-cads but they don't charge when the headphones are placed on the headphone cradle/charger.

The AR AW721 headphones require 3 AAA NiMH batteries, not Ni-Cad. The original batteries are 1.2 volt, 550 mAh. I replaced mine with Energizer 850 mAh AAA batteries, which work well and actually last longer per charge than the originals.

Just bought a second hand Canon Powershot SX100 IS.

Try cleaning the battery contacts in the camera first with a pencil eraser and then with a cotton swab lightly dampened with rubbing alcohol.

How are u suppose to charge the vtech camera

I just read the "User's Manual". It recommends using 4 standard Alkaline AA size batteries. These are not re-chargeable. You can use Ni-Cad rechargeables, but I don't recommend it. They are of slightly lower voltage and this may cause you problems with the cameras operation. I recommend reading Page 3 of the "User's Manual".

This is not specific to your camera, just general advice. I think that Ni-MH rechargeable batteries are recommended for most digital cameras. However, you should be able to use normal alkaline batteries too.

Yes, but do not expect your ni-cad batteries to last as long.

Lumix LC-DMC40 Camera Charger

what type of battery does it take? If standard AA type then a normal Ni-Mah or Ni-Cad will do it with a couple of sets of cells. Some cameras -one of mine in fact - will take AA's even though a special one is the preferred type.

How can I increase battery life?

Transferring images from the camera to the computer requires a lot of battery power. It is recommended to use the AC adapter when transferring pictures to conserve battery life. If not using the AC adapter, make sure your batteries are fully charged and use the highest possible serial speed when connecting the camera to the computer. After transferring your images remember to shut off the camera, otherwise the camera will remain "awake" and will continue to wear down the batteries. The LCD display also uses much battery power and should be used sparingly when trying to conserve power usage. Battery life can be improved by using AA sized lithium batteries, rechargeable AA Ni-Cad batteries, or rechargeable AA Ni-MH batteries instead of AA sized alkaline batteries.

Sony DSC-P93 battery replacement question

NiMH batteries. You can use the larger mAh AA. It has more capacity and should give you longer service before needing recharge. The battery manufacturers recommend that you do not mix the batteries. i.e. don't use mAh 2100 and mAh 2500 as one set, use all 2100 or all 2500 as one set.
