Transformer and Electric grenade

I heard that a storm front grenade helps heal the shield of the transformer shield, yet it does not cause my shield to regenerate. Am I doing something wrong, or is there a better electric grenade to quickly heal my shield? Thanks.

Shoot yourself in the foot with a splash shock weapon and your Transformer should heal (I use a Blue alien Hyperion shotgun with major splash dmg.) sometimes you can run over the Stormfront leaders to heal it as well.


Thanks! Are there any grenades that can do that as well?
