如題,因為正在打算多買四顆電來用,但不知是否需同一牌子.
還有,有那個牌子的電又平又好用?

Technically it can be used to do that. However, as each brand might have different specifications, you should avoid doing so.

Since the cost of rechargeable batteries do not differ significantly, it is better that you buy the same brand as your charger.
