Triplett Chek-A-Cell – PN: 3276 - Manual (Page 3)

INTRODUCTION:
The CHEK-A-CELL is a digital battery load tester for all types
of batteries in the 5.75 Volt to 20 Volt, 1 to 20 Amp Hour range.
Rechargeable batteries that may be tested include Sealed Lead
Acid, NiCad, NiMH, Lithium Ion (Lion), and others. Non-re-
chargeable (disposable) batteries may also be tested. These are
commonly Carbon-Zinc or Alkaline batteries. The CHEK-A-CELL
is often used to load test 6 volt or 12 volt sealed lead acid bat-
teries. These types of batteries are often used for backup power
in Emergency Lighting, Security Systems, and Uninterruptible
Power Supplies (UPS). They are also used as a power source in
many portable garden tools (weed wackers, small lawn mowers,
etc) and children’s electric cars and motor bikes. NiCad, NiMH,
and Lion batteries are common power sources for portable power
tools. By applying a load to the battery and measuring the bat-
tery’s voltage, the CHEK-A-CELL helps to determine the battery’s
condition.
Battery Testing Notes:
The CHEK-A-CELL contains an internal “load” for testing batter-
ies. This load will heat up while the battery is being tested. The
test time must be limited to prevent the load from overheating.
Generally, 5 seconds is a sufficient test duration to determine
a battery’s condition. Higher voltage batteries will heat the load
more quickly than lower voltage batteries.
WARNING!
Do not apply battery voltage to CHEK-A-
CELL for longer that 10 seconds.
Allow CHEK-A-CELL to “cool” for
3 minutes between measurements.
If testing a rechargeable battery, the battery MUST BE FULLY
CHARGED prior to the test. In backup power applications, the
battery is usually under constant charge, and should be fully
charged at any time (unless just recovering from prior usage).
