Replacement Battery for JOOYON J5 J357BAT

This new lithium-ion pack is built to replace the original JOOYON J5 J357BAT battery in compatible laptops. It delivers a nominal 7.6V and a rated capacity of 4800mAh for 36.4Wh of energy storage. The pack arrives in its original packaging and carries a three-month warranty from the supplier. It suits owners of the J5 series who need a direct, like-for-like power source.

Li-Ion chemistry and direct-fit design

The cell uses standard lithium-ion chemistry and is shaped to match the factory battery footprint, so it slots into the existing bay without adapters or case modifications. Connectors align with the motherboard header, meaning installation only requires opening the laptop base and swapping the old pack. No soldering or additional wiring is involved. Buyers who need a higher-capacity alternative or a different voltage will not be served by this model.
