I just got my new battery pack for my MS from GeoMan and I thought I would give it another try. With the original battery pack, the lighted button evidently would kill the battery over night if the indicator was on orange. GeoMan said to disconnect the battery at night which is a hassle. I was wondering, have any other MS owners found it necessary to disconnect the battery, especially the new replacemnt one, over night?

Considering I like to have a full charge for every ride day or night the first thing I do after hanging my bike up is plug in the battery..The hassle is not the 5 seconds it takes to plug it in it's the getting smashed by auto when your light is dead..

I never had to disconnected at all. Last time I check, that indicator LED behind the button only draw 6ma from a MJ808 while it was green. I doubt the yellow indicator draw any more than the green. That is not a load that should be of a concern even if you left it hooked up overnight for 10-12 hours.

How long did your light ran and at what mode before turning orange. The only thing I can think of is that either the old battery was defective and had a high rate of self discharge or your indicator is not so accurate and the yellow warning should be more like red because you are at the end of your battery pack runtime.

Thanks for the reply, Colleen. I can't remember the run time before turning orange because it was a long time ago that I turned in my original battery for the recall. IIRC when the light is orange this indicates 25% power remaining so I guess the indicator is inaccurate with the original battery. The indicator on my Cygolite Pace 310 is supposed to blink to indicate remaining charge but it doesn't. The Cygolite left me in the dark twice on my way home. Maybe these charge indicators are not worth much. I'm going to give the new MS battery a try and see how it goes but will be ready to grab the Cygolite if the MS is dead in the morning. It's really a hassle having to unplug the cable, especially since the new cable plugs are tighter fitting. I'm afraid I'll break the wire or something.

The new battery is even worst interacting with the charge level indicator. Many member who recieved their new pack noticed their low battery indicator warning turning yellow or red mucch earlier than it should but the battery still run for a long time.

I noticed it happens more often when I run it with a extention cable and having the battery mounted at the back of the bike. It gets worst when I run my tail light off of the same battery that's also running the lighthead. However I still get the runtime out of the pack.

I use a MS 808 on the helmet and a MS 872 on the bar. I do not disconnect each night or on the weekend. I too don't think the glow light on the button draws enough to make a difference. One note, the batteries from MS do not come fully charged, you need to discharge them, then give them a full overnight charge to test them.
One way not to worry about the light dying 1/2 way home in the dark is to have two lights. I let each of my lights draw down to red, then run it on strobe or low until I get home or work, then charge them. They are at different charge levels, so they do not run down to red at the same time, and they can run on red for most of my 45 min commute if I put them on strobe or low anyway. I typically get around 4 days of commute morning and evening 45 min each way with the lights on strobe or low most of the time.

I think I would be happy if my MS ever got to red, but it seems to get to orange, then go dead, with the old battery anyway. I ran it for about 20 minutes this morning and the light was blue when I parked it at work. On the way home I didn't use it but hit the on button, then back off. The light went to green and stayed there. Methinks the light is more for amusement than function.
