Rejuvinating old cells

[losidan]

wonder if I can ask a question about cells?

i have found three sets of team orion 2400 cells I forgot I had. They are currently in saddle formation.

I was thinking of getting two packs rebuilt into 4 cell packs for me 12th scale. I know they must of been sat for at least a year. Is there anything I can do to rejuvinate them if they are a little flat, so to speak. My charger has option to charge at 1,2 or 4 amps.

I wondered if a charge first at say 1 or two amps would be beneficial to breath some life into them?

frankly i know cock all when it comes to cells so any ideas would be most welcome.
