Answer:
The internal battery of the jump starter is NOT replaceable. However, there’s no need to replace the internal battery. Before telling you the reason, it’s better to be clear about the following information to entail a better understanding:
General lithium battery’s lifespan:
- Typically, a modern lithium battery’s lifespan is 2–3 years, which is over 500 fully charge-discharge cycles as rated by manufacturers.
- This doesn’t mean that your jump starter will die or won’t work after 2–3 years. It means that after 300 to 500 full charge cycles, the actual battery capacity of the jump starter may drop by 20% and the starting performance will decrease a little.
Here is the Cycle data of HULKMAN Alpha jump starters:

Thus, the battery capacity will drop about 20% after 500 full recharge cycles. The lifespan of our products is definitely long enough under normal use, which means there is no need to replace the internal battery.
