The utility model discloses a replaceable type module polymer lithium battery, which comprises a plurality of single battery bodies in identical structures connected serially in sequence. Each single battery body comprises an insulation casing, an upper cover and an electric core group. The electric core group comprises a plurality of pieces of electric cores, wherein each two pieces of electric cores are connected in parallel to form a group, and the groups of electric cores are sequentially connected in series to form the electric core group. A lead-acid accumulator can be directly replaced. Additionally, if some single battery body is abnormal and affects performance of the whole battery during use, the singe battery body can be replaced. The operation is easy and does not affect utilization of the battery. Meanwhile, batteries with different voltage can be formed by connection according to requirements of users.
