    Super Brain 989

    I just got my super brain 989 charger and with the exception of the instructions it's great. The instructions however suck so bad that I'm contemplating sending the damn thing back.

    There's noting in there about how to charge a 12V Gel cell.

    They should have a "Flow Chart" as to how to set the charger for how to charge different types of cells.

    RE: Super Brain 989

    I have to agree that the manual leaves most people scratching their heads. I've has to study the manual but still don't know how to do what I bought it for. I was hopeful to find help on this forum but there are only a handful of threads regarding the 989. It is a great charger for the basics but someone like myself who wants to go deeper into it's advanced functions will be left experimenting alone.

    RE: Super Brain 989

    This is kind of an old thread, but as long as I'm here in Academy/MRC, I'll add my comments.

    I photocopied the manual. Then penciled in and high-lighted
    989 Field Manual - ahr43. That way I can pencil in what works for me in the margins or on the back of the sheet. I do mostly simple charge / discharge of LiPo's at a 2amp charge rate and 4 amp discharge rate. I also use it for charging a nitro receiver pack.

    Agree with Snake in that it doesn't provide much guidance on how to charge a 12V gel-cell. I used one for years in a nitro starter box as a pit power supply for the 989. Always re-charged it from another source, not the 989.

    For me, the only realshortcoming of the 989 is the little green plug on the output side. The tiny set screws that secure the charging leads loosen up frequently and require constant attention. That detracts from it's usefullness as a field charger. It's o.k. for shop use.

    I'd like a backlit field too. But, like so many other chargers, it doesn't feature one. I do night racing in San Antonio during the hot summer months.I pit what I call a "cold camp". Meaning I don't use 115vac or a generator. I rely on 12vdc. That gives me flexibility in choosing a pit site and lightens the load I pack. That also means I have less pit light than most, so backlighting would be a nice feature.

    Overall, I rate the 989 acceptable. I still use it mostly because there are so many chargers out now that I don't know which one to buy, so stick with what works for me, the MRC 989 Super Brain.

    RE: Super Brain 989

    That would have been a nice feature. Sometimes during indoor events, it is difficult to read a screen without backlighting. I am now in the same boat as snakewriter trying to charge a 12v gel with the 989. I'd seen a post on here where you set the 989 to lead acid mode and choose 2 cell but the cycle ended too quickly so I left it trickle charging all night. This is a brand new battery and can only hope I didn't just screw it up.

    RE: Super Brain 989

    I have yet to try this most advanced charger of the MRC Name. People at the track however like the charger.
    But most hardcore Lipo users at the track are going to the Hyperion chargers. I dont much know
    about hyperion so I'll stick with my MRC chargers because of the first rate quality customer service.
    Hyperion doesnt have the support to lead up to thier name apparantly.
