Cycles Battery Backup Unit

[Josue99]

Hello everyone!

I'm have trying to learn the cycle of the Battery Backup Unit, how many cycles? etc.

Greetings.

What specifically are you looking for?

The learning test cycle schedule (which is every 28 days I believe)

The expected life span?, etc

Original BBU/battery, LSI listed replacing every year (or 500 recharge cycles), although we saw those frequently last 3-4 years.

For the Supercap I have not seen published data from Broadcom/Avago/LSI.

The CacheVault-05-UG100_Cache_Backup_Products_UG_v1.0_2017-07-31.pdf doc you can find on Broadcom's website, only mentions the BBU expected replacement cycle, and nothing about expected replacement cycle for SuperCaps.
