I have a couple of older (read 2012 and 2014) BCL14181H chargers. It's a 1.5A "Fast" charger.

My batteries are from the same era and while they are still working, one has started flashing an error on its last charge… so it's probably time to look for a new battery or two. The current set of four 2.0Ah batteries + one 4Ah are sufficient for my home needs. Even if their capacities are down, I rarely run out of a single battery mid-job, so as long there is no swelling and they charge, I'm good (unless someone can tell me why I shouldn't be??)
In any case, the manual (unsurprisingly) hasn't been updated in a long while and it seems there was a transition to the current form of the batteries and chargers.
Now the new chargers look like they are more flash, so I lean towards needing a new charger, the manuals seem to not list the old batteries from compatibility too… so maybe I need an old charger for the old batteries and a new charger for the new ones??
Which leads to the next few thoughts. Batteries by themselves vs just buying new tools with batteries and chargers because the pricing structure is stupid.
Before we get to that, most of the cheaper sets come with the basic charger which can't be wall mounted (which my current ones are). The RC18115 is only a 1.5Ah charger and looks remarkably similar in capability to my old ones, which reflects the original question on if they are interchangeable?

Onto Battery options (at Bunnings as at 28/12/22):
1 x 4AH = $139
1 x 4Ah with wall mountable charger = $104.30 WTF??
2 x 4Ah = $199 but if I need a charger this adds to the cost
4 x 4Ah = $249 and is likely best value if you need that many batteries but still need a charger.
But with tools, none of which I need and I would only buy because it's better value than batteries alone):
1 x 4Ah + 1 x 2Ah + Hammer Drill = $132 but the non wall mountable charger
1 x 4Ah + 1 x 2Ah + Hammer Drill = $199 Different model drill, but wall mountable charger for the extra $$
The sane answer is to just buy a single battery and charger for $104.30, drop it on the wall mounting I already have and call it done for one. Even if I need a second one later, it's still barely more expensive than that $199 set (and I don't have another tool I don't need).
Am I missing something in this line up?
I'd look at buy the battery and charger, and buy a Powered Rotary Hammer (I hear the Ozito is okay, as it's far better than the Hammer drill (as long as you have a long extension cable). Ryobi were clearing them out in July
