First of all equalise.

Second try a low rate charge (1A), repeaking if it cuts off, but monitoring cell temps too (no more than 45C).

Once the cells peak and they are warm, discharge and equalise again.

Do these cycles a few times and the cells should be back to life. Don't expect them to be any good after such a long time stored though, but might be usable for practice/club nights.

cycle for a few time's. Charge at 1a 1st time discharge and then recharge at 1.5a ect and keep going till there back up to top spec.
