1. There is absolutely no reason to be so rude.
2. I cannot find any verbage covering this in the warranty (aside from the fact that batteries are considered consumable parts and not really covered by a warranty):
"This warranty does not apply: (a) to consumable parts, such as batteries, unless damage has occurred due to a defect in materials or workmanship; (b) to cosmetic damage, including but not limited to scratches, dents and broken plastic on ports; (c) to damage caused by use with non-Apple products; (d) to damage caused by accident, abuse, misuse, liquid contact, fire, earthquake or other external causes; (e) to damage caused by operating the product outside the permitted or intended uses described by Apple; (f) to damage caused by service (including upgrades and expansions) performed by anyone who is not a representative of Apple or an Apple Authorized Service Provider (“AASP”); (g) to a product or part that has been modified to alter functionality or capability without the written permission of Apple; (h) to defects caused by normal wear and tear or otherwise due to the normal aging of the product or ℹ if any Apple serial number has been removed or defaced."
Not that it matters to me, but it may matter to the OP if they are basing their decisions on your advice because you are still contradicting yourself. But, since I prefer not to have a conversation with someone who is shouting at me, I am done with this thread.
For the OP: good luck with your visit to the store!
