(note: I'm writing in english, as I tag @wk057, so he can understand and potential comment too.
@wk057 reported ( #15,490 ) that he saw at least one customer come with a paid reman battery (=gereviseerde battery) from Tesla, who had very low range and indeed still very slow Supercharging speed. So it is important to understand that apparently, paid reman batteries, while they do come with 4y warranty, there is no warranty on the capacity or performance.
Here also, changing modules is not recommended, as it is a short term solution, with no warranty that other modules will not fail soon, and more important, it seems that module replacement/matching is almost doomed to fail sooner than later.
If really the battery is the problem, the better option, imo, if you want to keep the car for a longer time, is to replace with a new battery. Tesla has a new 90kWh, 350V solution for "our" cars, which provides better capacity than original 90kWh batteries, and faster SuC speed ( #48). Seems based on 100kWh packs, with 2 modules removed, so benefit from more recent chemistry & tech.
That being said, @wk057 noticed that 350V means more amps are actually going thru the car for the same power, so there is that too.

Thanks for the English
Tesla's reman non-warranty replacement batteries seem to be hit or miss from what I can tell. Sure, they'll give you a warranty on it, but that warranty doesn't cover degradation. Supercharging is also going to perform as well or poorly as the original pedigree of that reman pack.
It's sometimes the least expensive option to get the car back on the road, depending on what the actual issue is, but it's not always the best option.
The newer higher capacity 350V batteries are an interesting option. They'll improve supercharging speeds, but the long term effect is more current then originally intended for many components, since the voltage is ~12% lower at rest and ~20-30% lower under load. To me, this seems like long term the pack will degrade more quickly, and other components in the car (motor and other HV components) will see additional heating under load vs previously... and heat is generally one of the worst things for electronics.
So I'm personally a bit torn on these 350V options.
That is one of the reasons i opted for the performance model in 2013, as that seems to be fitted with sturdier power cables able to handle higher voltages. I'm not exactly sure about that though.
The high voltage wiring on all S's is actually the same regardless of performance or non-performance. This only changed slightly with the release of the small dual motor rear motor, which has a slightly lower gauge wire from the junction box to the motor than previous cars.
