    hi, im gems. i just want to ask any idea about the battery. im just wondering why most multimeters use non-rechargeable (Alkaline Batteries) than rechargeable (Ni-cd or Ni mh) battery? i search on the internet websites about the comparison between these two. but im not satisfied with the answers. is there any reason why most devices use non-rechargeable battery?

    hope you can help me.

    thanks

    My guess would be that the non-rechargeable batteries have a flatter discharge curve.

    probably through even moderate use a multimeter battery will often last a year.

    Cost difference, not performance--Ni-cad and NiMH have flatter discharge curves but are more expensive.

    Rechargeable batteries only become cost effective at higher power consumption rates. Meters use very very little power.

    Non-rechargeable batteries have a useful mean voltage of 1.5V (1.6V max.), and rechargeable NiCd batteries have a mean voltage of 1.2V (1.4V max.).
