Brother I am not an expert, but I would like to add a few things:
When hybrid vehicles are brought here after auctions, it definitely takes 3-6 for them months to reach here, but I will consider this as an exception that they had not been driven for 3-6 months.
This is not a usual practice and can never be a usual practice that if a hybrid car is not driven for 3-6 months, then no problem. Batteries kuch cycles takk to 3-6 months without charging ki beating ley lein gee, but in the long term and long run, I think this practice will shorten batteries life. Yahan, 3-6 months ka gap aa jata hai, otherwise, in the countries where these are manufactured and sold, this is not the case.
Brother if you could kindly share the source / link of this information or some document, I would be highly thankful to you (No offense and I do not mean to be rude).
Thank you.
