yes, I know what you mean..Best way is to use rechargeable batteries..You have to take a look on the mili ampere per hour (mah) e.g. 2100mah or 2300mah is fine! another example, mate:
Both NiCd and NiMH batteries are rechargeable. The main difference between the two is the fact that NIMH batteries offer higher energy densities than NiCads. In other words, pound for pound, NIMH delivers approximately 30% more capacity than its NiCad counterpart. What this translates into is increased runtime from the battery with no additional bulk. NIMH also offers another major advantage: NiCad batteries tend to suffer from what is called a "memory effect". What this means is that when a NiCad battery is only partially discharged before charging, the battery "forgets" that it has the capacity to further discharge all the way down.
