Disclaimer: Do this at your own risk. This is not a tutorial and is for entertainment purpose only. Lithium ion batteries can explode or catch fire if mishandled.
The 12 volt 22 Ah sealed lead acid battery in the DieHard jump starter (model 1150) is not holding a charge anymore. Since I have many 12 volt lithium ion battery packs, I swapped out the old battery and attach two 12 volt 20 Ah packs to make the power station work again. I will not be using the power station to jump start an automobile as an extra layer of protection is needed to avoid damage to the lithium ion battery after the car starts and the alternator starts to charge the jump start battery.
Other than that, the power station retains the compressor, inflator and the DC to AC inverter function (400w).
