Changing the battery long before they're actually due for replacement is much more wasteful.

You don't need a 'Pro' battery analyzer. There are battery analyzers on Lazada for under 2k. They're good enough at determining your battery's general condition.

Run the analyzer every PMS. Once the SoH gets below 50%, it's time to save up for a replacement as the battery could die within the next 6-12 months. When it's down to 30% or lower, replace it ASAP.
