Rechargeable Battery

Can I use any rechargeable battery charger with any type of rechargeable batteries?
I have a panasonic charger for rechargeable batteries but the batteries are starting to not hold their charge as well. Do I have to buy a whole new set or can I use any rechargeable batteries with the charger I already have?
No. First check to see what type of batteries your Panasonic batteries are: If they are Nickel-Metal-Hydride batteries (NiMH) than you can charge other branded NiMH batteries or Nickel-Cadmium (NiCd) batteries in your charger. If the original batteries are NiCd then you likely can only charge NiCd batteries; you should know that those type of batteries (Ni-cads) are being quickly phased out due to environmental concerns.
Under no circumstances can you charge Rechargable-Alkaline cells in your charger.. those require a special charger (and don’t perform well in any case).
The numbers on the batteries (ie 2100 mAh) basically translate to how long the batteries will last (and charge); you can use larger valued batteries than your original units.
