Battery Upgrade?

[Peat's Adventure]

Hi All, I have a 1150GSA with heated grips, running an autocom and gps. I use a accumate charger, however my battery seems to keep going flat, resetting clocks etc... does anyone have the same prob? thinking about upgading the battery or the alternator, all help gratefully recieved

How old is the battery? Mine copes with all the normal stuff and a heated jacket without ever missing a beat and sits out in the cold all the time. I have been riding the HP2 for the last 4 weeks but the Adv started first try this weekend when I moved it.

Battery condition checks

Battery condition checks (stolen from Don Eilenberger on the IBMWR list)

"If you have a voltmeter - does it have an AMPS scale?

Let’s first check the battery: remove the negative battery connection
from the mounting point on the transmission, and then fully charge up
the battery (hopefully with something like a battery-tender or other
automatic battery charger).

Leave the negative terminal disconnected.

Measure the battery voltage after charging. I'd expect to see 13.3-6V
or so sitting on the battery.

Let the battery sit an hour - measure voltage again. It will
probably be closer to 13V at this point ("float charge" dissipated).

Let it sit overnight and measure the voltage. It should be in
the 12.8V range (+/- 0.2V)

If it is significantly less - then you have a bad battery, and it
has been known for a newish battery to go bad. That's why there
are warranties. To fully confirm it - you could have the battery
load-tested, but from the symptoms you describe, it sound as
if it's discharging overnight.

If it is where it's supposed to be - now take the meter and
turn it to Amps. If it is auto-ranging, that's fine. If not,
put it on the largest number scale it has for Amps (10A would
be good.) Connect it between the end of the negative cable and
the mounting point on the transmission. With NOTHING turned on.

I'd expect to see less than 100mA (really more like 25mA - for
the clock.) If you see more than 100mA, you have another problem,
something is drawing too much current and discharging your
battery. To find the something - leave the meter connected and
start pulling fuses. When the current drops significantly, you've
found the circuit the problem is in. Let us know what fuse it
is."
