Is an energizer ultimate battery 03-2027 rechargeable?

Answer 1

No, the 03-2027 "Ultimate Lithium" is a Primary (non-rechargeable) battery. Attempts to recharge primary batteries, such as standard Alkeline types, often appear to succeed but, in the process, damage internal structures including the battery's seals. The price of a new battery is a small price to pay to avoid ruining your electronic device with leaky batteries. Depending on the specific chemistry, Lithium batteries can spontaneously and abruptly disassemble if electrically abused and attempting to recharge Primary batteries qualifies as abuse. Just don't.
