2.0  Preparing for Maintenance

The battery system should be remotely monitored monthly and physically inspected quarterly. If the 

battery system has an automatic monitoring system to gather the electrical and environmental data, 

the monthly checks should consist of evaluating the recorded data and visiting any site that does not 

meet the specifications listed in the detailed procedures below.  At a minimum each site needs to be 

physically inspected every three months.

You do not have to measure the electrolyte specific gravity or add water to the cells.

All batteries in the string should be numbered to facilitate recording and analysis of data unique to 

each unit.
Notify anyone affected by the intended maintenance or troubleshooting activity.  This should include 

but not be limited to anyone responsible for the status monitoring equipment at the head-end or NOC.

2.1  Required Tools and Equipment

Prior to beginning maintenance, ensure that all required tools and equipment, including safety
equipment, is available and functional.
The following is a list of the minimum equipment required to maintain and troubleshoot the
AlphaCell GelCell battery:

• 

Digital voltmeter

• 

Socket wrenches, insulated

• 

Box end wrenches, insulated

•  Torque wrench calibrated in inch/lbs
• 

Rubber gloves

• 

Full face shield

• 

Safety Glasses

• 

Plastic apron

• 

Portable eyewash

• 

Spill kit, including sodium bicarbonate solution

• 

Fire extinguisher

• 

Optional equipment, depending on the type of maintenance being performed, 

includes:

• 

True RMS Volt Meter with DC Amp Clamp

• 

Midtronics Conductance Meter

• 

100 amp momentary load test set

• 

System load bank (DC if to be performed at the battery and AC if to be performed 

by loading a power supply output— contact your Alpha Sales Representative for 

purchasing information).

• 

NO-Ox Corrosion Inhibitor

•  Paper Towels and/or rags
