Battery Info
RATE-FAST

Three 1.5V alkaline C cells
•
cost approx. $1/each; widely sold (Costco, Home Depot, etc.)
•
use quality alkaline batteries (e.g., Energizer)
•
rechargeables (not recommended) last 40% to 70% less than alkaline batteries
•
in extremely cold climates (consistently below -20C / -2F) plan on 50% less battery life
•
battery failure risk increases above 55C / 131F
•
maximum total voltage: 5V
G4 counters
8 to 9 months
G2/G3 counters
7 to 8 months

NOTES
•
Limitations: Two or more bikes in the detection zone at the same time may be counted as one.
•
After the counter begins recording data (i.e., after
START
is reached), counts are recorded if you
move the counter, or move ferrous metal objects (e.g., shovel) near it.
To better secure
the batteries,
particularly if
moving the counter,
use duct tape.
•
turn battery holder upside down
•
tape from side to side as shown
•
it is only necessary to tape the
two batteries shown
