There are two types of battery tests: 
Unloaded and Loaded. The unloaded test is 
the procedure that will be discussed. It’s the 
simplest and most commonly used. An 
unloaded test is made on a battery without 
discharging current. To perform unloaded 
testing, check charge condition using either 
a hydrometer or voltmeter. 
1.  Using a voltmeter, voltage readings 
appear instantly to show the state of 
charge. Remember to hook the positive 
lead to the battery’s positive terminal, and 
the negative lead to the negative terminal. 
2. A hydrometer measures the specific 
gravity of each cell. The specific gravity tells 
the degree of charge; generally, a specific 
gravity of about 1.265 to 1.280 indicates full 
charge. A reading of 1.230 to 1.260 
indicates the battery should be charged 
before testing. The Battery Condition Chart 
shows the charge level as measured by 
syringe float hydrometer, digital voltmeter 
and five ball hydrometer. 

1.  Remove battery from carton. 
2.  Place battery in a well ventilated area on a 
level non-concrete surface. 
3.  Remove battery cell caps. Fill cells as 
required with electrolyte (purchased 
separately) to proper level. Fill to 3/16” 
above cell plates. Filling battery with 
electrolyte will bring the battery to 80% 
charged state. 
4.  With cell caps removed, connect battery 
charger to battery terminals; RED to positive 
(+) and BLACK to negative (-) terminal. 
 
 

IMPORTANT: 3/16” above cell plates is the recommended 
level. DO NOT place anything in battery other than specified 
electrolyte. 
 

5.  Slow charge the battery at 1 amp for 2 
hours to bring the battery to full charge. 
6.  After charging, check level of electrolyte 
and add as needed to bring level to 3/16” 
above cell plates. 
7.  Reinstall cell caps. 
8.  Install battery into power unit. 
9.  Connect positive (+) cable (red) first, 
from wiring harness to the positive terminal 
(+) on battery using bolt and nut provided 
in hardware bag. Connect negative (-) 
cable (black) last, to negative terminal (-) 
on battery using bolt and nut. Apply a small 
amount of grease over terminals to prevent 
corrosion. 
10.  Install battery retainer and positive 
terminal cover.
