Reedy Lipo Low Voltage

[Eiremaxx]

Hi Guys Its been a while hope your all keeping well,

Quick question

I Have 2x reedy lipo 5000mah cells and was trying to charge them the other day but when i try to charge them it says low voltage i was using one of them every few months but the other was in storage i'm thinking these lipos are knackered but on the off chance is there a way to revive them?

Regards
