9.0 – MAINTENANCE 

 
The EP is maintenance free.  The batteries used in 
the system will require maintenance and eventual 
replacement. 
 

9.1 – Battery Maintenance 

 
Gel or AGM batteries require little maintenance.  
However, all system connections should be checked 
once a year for corrosion. Corrosion, if any, usually 
occurs at the battery terminals or posts.  Corrosion 
should be removed and the connections cleaned: 
 
1. 

Use protective eyewear and gloves

2.  Turn the INPUT and OUTPUT switches OFF

.

 

3.  Disassemble the corroded components and 

remove the corrosion with a stainless steel wire 
brush.  The metal parts should be bright. 

4.  Reassemble the connections.  The connections 

are soft metal; do not over-tighten. 

5.  Wait several minutes then re-tighten the battery 

connections. 

6.  Turn the INPUT and OUTPUT switches ON. 
 
NOTE:  For systems showing signs of corrosion, it is 
recommended that a corrosion inhibiting grease is 
applied to the terminals after final tightening. 
 

9.2 – Battery Replacement 

 
Most Gel and AGM batteries require replacement 
after approximately 5 – 7 years of standby service at 
the ideal temperature of 75°F (25°C).  Generally, 
batteries in outdoor enclosures and hot climates last 
from 3 to 5 years.   
 
Because battery temperatures, usage, and quality 
vary from site to site, we make no recommendations 
regarding replacement intervals for batteries.  It is 
generally accepted that a lead acid battery should 
be replaced when it falls below 80% of its rated 
capacity, at the factory specified rate of discharge.  
You may perform the test described at the end of 
Section 8.3 to determine if your battery has sufficient 
capacity for your application. Hold-up (discharge) 
and recovery times are shown in Graphs 6.5.1 and 
6.5.2 in Section 6.5. 
 

Lead and other materials used in batteries are 
toxic and present hazards to our environment.  
These materials also have value and can be 
recycled.  Nearly all recycling facilities accept 
batteries.  Comply with all Federal, State, and 
local regulations when disposing of batteries.  
Please recycle!
