Question

I had a Pokemon that had the ability.Traded it and forgot what volt absorb does.

Answer 1

http://bulbapedia.bulbagarden.net/wiki/Volt_Absorb_%28ability%29

When a Pokémon with Volt Absorb is hit by an Electric-type move, its
HP is restored by one quarter of its maximum HP, and the move will
have no effect. This includes the effect of activating a Cell Battery.
In Generation III, Thunder Wave is unaffected by Volt Absorb.

BTW: Fun fact!
Volt absorb is only an ability on six electric type Pokemon!

Answer 2

If you get hit with an electric type move, the attack does no damage and heals HP.

A Pokemon with Volt Absorb heals 1⁄4 of its maximum HP when hit by an
Electric-type attack.
