LifePO4 Battery No Voltage - Won't Wake Up - Try this fix first

Published 2024-03-25
My 200 AH LifePO4 RV Battery would not wake up and appeared swollen. I opened it up and did some investigating to save it. In the end the battery was was brought back to life but not because I opened it. I hope this method helps anyone who had this same issue. Enjoy.

You can find batteries with a wake up power button at either of these sites.

    Thank you for this! I thought I had smoked my motorcycle battery but this revived it.
  • @gpmail
    I am in a similar situation. My 12V lifepo4 drained off grid during off season and went into protection mode. Hard to tell when during last few months. I was able to reactivate it at first and started charging it off solar on a Victron smartsolar. After a day of charging sucessfully I managed to drain it again with only a small load when the sun went down. It went into protection mode again and won't wake up now. :/
  • The issue I am having is the battery reads 12v but as soon as you hook something to it it reads 0volts. No power. Any suggestions?
  • @herblapp6134
    I notice you look like your charger is a pretty standard one. I have one andused on my deep cycle lead acid batteries for charging. I swapped the lead acid out for lithium ion iron phosphate batteries.l see specialized lithium ion chargers and they're costly. Can l use my standard battty charger?
  • I am having the exact same problem with a 280AH LifePo4 battery in my camper, except it’s brand new. The mfg suggested linking it straight to my solar bank, which I’ve done with no success. Any updates on how you got yours to wake up? I have a spare 12v battery but it’s a big boy and I’m hesitant to do the tapping method with it.
