Having so many batteries you seldom use sounds like a you issue, not a Milwaukee issue.
Tell me which battery you know of lives a long life with seldom use?
Your entitlement is the bigger problem, however.
If you need to use a high draw tool remotely, were you don’t have a power source, then you might need a lot of batteries to insure you can get the work done.
Some people have to do this type of work, but but frequently enough to be running their batteries down fully each month for recharge.
As fir Milwaukee and their batteries, they’ve had various issues since decades ago when their batteries had the stick design on top that inserted into the tool, and the batteries were made in Mexico, for USA made tools.
One of the Mexico made battery designs had vent holes on the bottom, that could get clogged ip leading to potential explosion issues.
Milwaukee had to recall that series of batteries.
The batteries also had a low amp hour rating of maybe 1.2Ah rating.
Milwaukee later switched to Japanese made batteries that slid onto the tools forwards or backwards.
The Ah rating was at least doubled.
These batteries were generally good, but I ran into more than one person who had batteries with badly welded battery cells or a bad battery cell or two in their tools, leading to lower performance.
Their complaints were that it was too hard yo get the batteries warranted from Milwaukee or their service centers, although I never had to deal with the issue myself.
Milwaukee was part of AEG and Atlas Copco at this point, with tools made in the USA, and Germany and the Czech Republic, and maybe elsewhere.
The European batteries were made inEurope, likely using European made battery cells, with a lower Ah rating for NiCd battery packs than the US Japanese made NiCd battery packs, but there were also NiMH battery packs with a higher 3Ah rating available, as well as 10-15 minute battery chargers.
Then Milwaukee came out with their 24V (or were these the 28v tools) Lithium battery tools.
I’m not sure whether this is the same system that is still available.
The tools were bulky, and heavy, as were the battery packs.
The tools from what I recall were also more expensive then the older NiCd tools by maybe double.
Then Milwaukee came out with their first 18v Lithium battery system.
If I recall correctly, this had major issues and was discontinued and replaced by a different lithium battery system within a few years.
Then Milwaukee came out with the current lithium tool batteries (I think).
Basically though, the various Milwaukee battery systems have had issues over the years.
The battery tools also tend yo cost twice what the corded tools used to cost.
The older Milwaukee NiCd batteries sometimes sat on shelves for 10 years before being sold, and would usually still charge up well after a few charging cycles, despite sitting for ages.
As for other companies with battery issues.
Apple literally had an issue with their battery manufacturer about 15 years ago.
Other computer manufacturers had the same issue due to the same supplier.
Apple initially denied the issue, but once it became known there was an actual manufacturer issue, Apple apparently started supplying replacement new batteries, from a different manufacturer, even for computers that were out of warrantee.
The Apple batteries were all of $120 new if I recall correctly.
Apple did the same for the Logic boards made with Nvidia graphics cards that failed once the issue became known.
