MSA1000 Cache Batteries are 5 years old - no issues - replace for age ?

If the cache batteries in an MSA1000 are now five years old and are having no issues should they be replaced due to age ?

Primum non nocere - first do no harm

if your cache batteries are not complaining that they need to be replace, no, don't proactively replace a part for old age. i have a 10yr old trinitron thats still kickin', i ain't going to replace the tube b/c its old.

and either way, if and when the batteries go, they won't cause an outage.

Last I heard these batteries are good for 3 years. As batteries age their internal resistance will increase. While they may look good if you measured there voltage you will find that under load the voltage could drop below specification. Which means that they may not hold your cache when the power fails.

There is also a concern that the batteries may start leaking electrolyte causing corrosion of the contacts.
