APC 350VA UPS Battery Backup BK350 The Home Depot Rated 4 out of 5 by ravi from nice product old software documentation doesn't match the software, which is odd since the software itself hasn't been updated in 5 years so how old does that make the documentation? I replaced the battery in my UPS but the software (v3.0.2) reflects I have less than 1 minute of battery. The documentation says to reset the battery replacement date, but where?

Nickel–metal hydride battery A nickel metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery.The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen absorbing alloy instead of cadmium.A NiMH battery can have two to three times the capacity of an ... Resistors | Ohm's Law | Electronics Textbook REVIEW: • Devices called resistors are built to provide precise amounts of resistance in electric circuits.
