11.5  Annual Maintenance

•  Repeat semi-annual checks.
•  Re-torque the intercell connector bolts to 71 in-lbs.
•  Equalization charge of 2.41vpc for 6 hours.

11.6  Bi-Annual Maintenance

The battery should be capacity tested every two years at 

the service load or at the battery rating related to service 

requirements. Ideally, this will be the same rate at which 

it was acceptance tested when originally installed. Once 

the battery is found to be at 85% of rating, it should be 

capacity tested annually. The above record taking is the 

absolute minimum to protect the warranty. This data will 

be required for any warranty claims on the batteries.

11.7 Cleaning

The  plastic  battery  containers  are  not  compatible 

with  many  commercially  available  chemicals  including 

cleaning products and insecticides. These chemicals can 

damage the battery case and cause leakage of sulfuric 

acid. If the battery needs to be cleaned, use water. Do 

not spray insecticides directly on the batteries.
