    heated grips drained battery - what to do?

     just installed some heated grips.

    they are RIVET brand. 

    work great, only prob is that after one week the battery is not drained and can only kick start. 

    what can i do to prevent this? get a bigger battery? change the 5amp fuse to a 3amp?

     

    anyone with any helpful hints..

    Turn the grips off when possible and recharge the battery. 

    If you must keep the heater on then use a 240V battery charger a couple of times a week to keep the battery charged.

    Turn them off when scoot is not running. They should be set up this way or have a separate switch.

     only have them on when running, and shut them off a couple of kms from destination.

     there is a on/off switch but somehow it still drained the battery.

    its wired directly to the positive and negative terminal as stated in the wiring instruction. 

    on the packet it also says to swich off when not in use as it drains the battery.. 

    done as per instruction but still had to kick start as not enough juice left for electric start..

    maybe the capacity of my battery is not enough to cope with the grips..

    Sounds right.

    Really it is the charging system that has to cope with the grips and keeping the battery topped up. A bigger battery may help in the short term but the charging system then has a bigger battery to charge up.

    Only things I can think of is battery may not be good, wiring set up perhaps not quite right, charging system capacity is down or the grips draw to much power for your scoot. I would check that no uninsulated wires are touching metal on the scooter and I understand some grip heaters are quite delicate when installing so check no breakage.

    Get a auto-float motorcycle battery charger and plug it in when bike is not in use . How old is the battery on your scooter is it still holding a good charge . It sounds to me your charging system is not powerful enough to power the grips and also charge the battery so a larger capacity battery is not going to help it wont charge that up ether

    You can limit the current they draw by putting a suitable resistor in the circuit. If you put too much resistance though, they will not get so warm.
