WARNING  
1. Working in the vicinity of a lead acid battery is dangerous.  
Batteries generate explosive gases during normal battery  
operation. For this reason, it is of utmost importance that  
each time before using your tester, (if you have any doubts)  
you read these instructions very carefully.  
2. To reduce the risk of battery explosion, follow these  
instructions and those published by the battery  
manufacturer and manufacturer of any equipment you  
intend to use in the vicinity of the battery. Observe  
precautionary markings on these items.  
3. Do not expose the tester to rain, snow or other forms of  
moisture.  
PERSONAL SAFETY PRECAUTIONS  
1. Someone should be within range of your voice or close  
enough to come to your aid when you work near a lead acid  
battery.  
2. Have plenty of fresh water and soap nearby in case battery  
acid contacts skin, clothing or eyes.  
3. Wear safety glasses and protective clothing.  
4. If battery acid contacts skin or clothing, wash immediately  
with soap and water. If acid enters eye, immediately flood  
eye with cool running water for at least ten minutes and get  
medical attention immediately.  
5. NEVER smoke or allow a spark or flame in vicinity of battery  
or engine.  
6. Be extra cautious to reduce risk of dropping a metal tool on  
to the battery. It could spark or short-circuit the battery or  
other electrical parts and could cause an explosion.  
7. Remove personal metal items such as rings, bracelets,  
necklaces and watches when working with a lead acid  
battery. It can produce a short circuit current high enough  
to weld a ring or similar item to metal causing a severe  
burn.

PREPARING TO TEST:  
1. Be sure the area around the battery being tested is well  
ventilated before performing any test.  
2. Clean battery terminals. Be careful to keep corrosion from  
coming in contact with eyes.  
3. Inspect the battery for cracked or broken case or cover. If  
the battery is damaged, do not use the tester.  
4. If the battery is not sealed (i.e. Maintenance Free), add  
distilled water in each cell until battery fluid reaches level  
specified by the battery manufacturer. This helps purge  
excessive gas from cells. Do not overfill.  
5. If it is necessary to remove the battery from the vehicle to  
test, always remove grounding cable from battery first. Make  
sure all accessories in the vehicle are off to ensure this will  
not cause any arcing.  
OPERATION & USE  
BATTERY TEST: BT-250 (12 Volt Batteries Only)  
1. Before you test a battery in a vehicle, turn off the ignition,  
all accessories and loads. Close all the vehicle doors and  
the trunk lid.

battery chamber. If the 9V battery runs out of  
power, screen will show “Ibtl” (internal battery  
low). Replace this 9V battery before beginning  
the test.  
3. Make sure the battery terminals are clean. Wire brush them  
if necessary. Clamp the black test lead to the vehicle’s  
negative battery terminal. Clamp the red test lead to the  
vehicle’s positive battery terminal. Tester display will  
illuminate when a 9V battery is installed and both clamps  
connect to the correct battery terminals.
