Battery charger. sufficient or not ?

  1. Hey Guys/Gals,

    i got a Battery charger with the following specs,

    pri 240v ~ 50HZ 63W
    12V - 16v -... 42VA

    Sec.: 9,8V -... 3A

    capacity range 1,2 3Ah
    time controller: MAX 90min

    would this be good enough to charge a ZZR250 dead battery. ????

    Thanks in advance,

  2. Can't see why not, though 1,2,3 Ah has me wondering.

    the zzr battery would probable be around the 8 Ahr range, but surely that just means you will need to put the charger on for 3 hrs if it was completly flat.

  3. Well I wouldn't go hooking it up to the 9.8v ouput. A low amp 12v output is fine for charging a battery, it'll just take longer (some batteries actually give the charging times for various amps). Having low amps is definately preferable to having the amps too high.
    Edit: Oh and FWIW I've charged my battery with a 2.6 amp charger before without problems, in fact the battery actually gives a time for charging at 4 amps (1/2 hour). Of course not all batterys are the same.
  4. If the battery is totally dead you need a low amp charger to start with or you can warp the plates and fark the battery. A good smart charger will sense the instant current drawn and self adjust, but a simple one will just give it the berries from the get-go and can easily screw the pooch.
