L3 Charging on new battery

[Beachman]

Have had the car for two weeks and put on 1200km - haven't used a L3 charger yet but would like to try it out but wondering if there is any reason to hold off on a new battery - other than say crazy hot weather which would stress it from the limited info I have read. Temperature now is the low 20C range (low 70F).

There should be no problem at all using a fast charger occasionally in these circumstances.
The best data we have to go on is from the study
Effects of Electric Vehicle Fast Charging on Battery Life and Vehicle Performance
There was little difference in battery degradation for the first 30,000 miles driven between cars purely charged L3 and those charged L2.
This was during the Spring.
Summer temperatures in Phoenix, Arizona were a problem. However this should not effect you.
