A:AnswerNot exactly equivalent. Same dimensions. LR44 listed as 1.5V while 357 is 1.55V. Certainly should be within tolerance there. But the 357 is a low-drain battery. If you use the LR44 in something that drains the battery in days or weeks, you need a high drain battery, and should not use the 357.
A:AnswerI don't know exactly which battery the Minolta XG1 needs, but the 357 battery has several equivalents, like LR44, SR44 and a few others. That's what you need to look into. The 357 is a very popular replacement for a number of different button cells.
