removed from the battery holder immediately after use otherwise the batteries will slowly
discharge and may leak, damaging the recorder and voiding warranty.
AA batteries can be alkaline, NiMh rechargeable, or lithium (1.5V). Make sure all batteries are
fresh and of the same type. Mixing old & new batteries or different types of batteries can cause
erratic detector behaviour and also cause batteries to leak. Battery life will depend on the
condition and type of batteries being used, as well as ambient temperature, length of your
recording session and amount of bat activity & ambient noise (if using triggered ultrasonic
recording). Four high-quality alkaline AA batteries last up to 300 hours of acoustic recording,
or up to 40 nights of triggered ultrasonic recording (based on 10% bat activity at 25
o
C and 10
hour nights). However, in practice recording conditions can vary, so be conservative when
using battery life estimates to avoid the loss of sampling time should the batteries run out
before you expect. Please refer to the
section for more details about how
temperature can affect battery life.
