    Magicshine Battery Recall - How long did it take for you to get your new battery?

    Just got my letter today and mailed the battery. Post office said it had to go ground not air. Guess I'll be using my backup front strobe for a while ...

    Last November, the company reported that the batteries were dangerous and should not be used. Most people already bought something else.

    Same here...

    I received the email notification that letters were going out on Friday, but I haven't gotten the letter yet.

    I've been using and charging mine all along too- no issues. I really don't want to be without a light for a few weeks- I ride at 5am. I'd almost rather just buy a new battery and then send the old one back and have 2 batteries.

    Mine continues to work fine. I just got the free recall notice in the mail but I am wondering if it's worth the hassle of pitching the current battery to get a new one.

    Do any of the battery gurus know if the new "made in usa" battery is really any better than a functional chinese model that has worked fine with no problems??

    Got the recall letter today. Is it common to have to return the old product to get the new one. That's a major hassle. I'm almost tempted just to keep using mine, which works fine.

    That's what I am asking. I don't know enough about battery technology to know if it's worth the hassle to return the old one for a new one. I am hoping some of the battery brainiacs (and you know who you are!!) in here will be able to give a good answer of the pro's and con's.

    I sent mine Priority Mail today. The Postal Clerk asked if there was anything hazardous in the package. I pointed to the label that I printed from the site that describes the contents as a Li-ion battery. The pack is a secondary Li-ion battery that is a mailable Class 9 hazardous material. He accepted the package.

    If you prefer not to ship the battery, there is an option to take the battery to one of the recycling centers on a list, have someone there sign the form, and then mail the signed form back to the recall center.

    BTW, I remember reading that they plan to ship the batteries to the people who have had them the longest because they are the ones that are most likely to be a problem.

    Anyway, my battery pack was pretty much dead, so I have nothing to lose here.

    I'm not a battery guru but I can give some pros and cons. Couple of things to keep in mind is the fact that LiIo battery pack will naturally diminsh in capacity over time even if they have no problems with mismatch. If you used your pack for a year now, most likely your pack performance will drop in the next two years. If you replace the pack from Geoman, you essentially will gain an extra year of service. One way to tell what is the condition your old pack is by running it down to see if you do indeed still get the 3hrs of runtime.

    The danger of continuous use of your old pack is the possibility of getting the cell unbalance within time. If you happen to be some of the few who happen to got matched cell in your pack, then your pack may be ok. However this still does not mean they are balance after one year of service. Your mismatch cell might only be a small error but over time, it will become unbalance raising the chances of having one or more cell getting hot from overcharging and catching fire. The new pack has a sensor for temp to help prevent that. The only way to tell is taking a reading of each cell with a volt meter.

    Why take that chance when you can get a replacement pack and reset the cycle counter back to zero? OTOH, the new pack is unproven and only time and field testing will tell. If they are a dud, then your old cell would have been better. I kinda doubt this though.

    I've been using mine, but the runtime has been getting pretty short and mostly for the last couple of months I've been using my Tenergy 8 cell pack. I just got the letter yesterday and shipped it today.

    I'm no "brainiac" - but I play one on the bike forums....

    I will offer these comments just as a "guess" - that's all just a guess about the "bad battery" situation.

    I think this is a case of possibly defective or damaged battery-cell "protection-circuit" boards. And there is no way of knowing if the boards are manufactured poorly, installed poorly or are being damaged by transportation mishandling or user error.

    But the end result is the possibility that they will fail to regulate voltage when charging the battery pack. In most cases, even if the board fails, the charger would still limit the voltage and current to the battery pack and you would simply have a hot, smelly mass melted battery cells beside your hot (but not on fire) charger.

    However, the battery cells can contain irregular or uneven concentrations of electrolyte. (cell jelly) If there is enough of an "air bubble" (or gas) trapped in the cell as it continues to heat over a long period of time the result could be an explosion. Along with the "pop" - the material ejected could be hot enough to start a fire or burn you.

    For anyone who knows how to use a multi-meter it is a rather simple process to measure both the current and voltage of battery and charger as long as you are willing to splice up your own cables to insert the meter in and across the charging circuit. If you take the time to observe the current decreasing as the voltage nears its cutoff point - you pretty well know all is well.

    Fully discharged batter packs will draw between 1.5A and 2.1A for a few minutes.

    Within five minutes any very high reading should have fallen to near 1.5A (if not you have a poor charger regulator)

    You should be able to "watch" the current decrease at about 10mA per minute for the several hours. This means you would see about .9A an hour later.

    Three hours later you would see a nearly fully charged battery, drawing somewhere around 20-30mA. If you check terminal voltage- it should be approaching 8.1-8.4V.

    That is all.






    But I don't know, this is just my best guess. In any case, I treat my batteries gently and do not let them get bumped or dropped.
    Sorry about my comments - I thought you wanted honest feedback.

    Just curious, did anyone get a letter from MagicShine directly? I bought one directly from the mfg., not from GeoMan. I doubt they are notifying but would be curious to see if they did....

    I'm not aware of anyone but GeoMan doing a recall. Honestly, I think the GeoMan recall is more of a CYA/publicity move. I'd be absolutely amazed if MagicShine did a general recall. Actually, more than that. I'd check to make sure I'm still on the right planet.

    I don't actually think that the battery "problems" were bad, or would have effected even 1% of users. But I'll still take a free new higher quality battery, now that I've pretty much used up the original battery anyway.

    I am still looking for a good solution to the weak connectors on the MagicShine system. As it is I have to replace my Y connector about every 3 or 4 months. Luckily they're about $3 at DX so I don't care that much. I think that I will probably cut off the waterproofing ring on the battery connector to make the connectors slide apart easily, since I keep that connector inside a waterproof pannier anyway.

    The last time I really used the MS, it died after 1 1/2 hours on a 2 hour night ride. I charged it for 3 hours and it ran for 30 minutes. Charged it again for 3 hours, it ran for 15 minutes. After that, it would only run for 5 minutes, so I put it away. It never caught on fire, but it failed.

    My choice to get a new battery through the recall was obvious. For those with a battery that still functions, the choice is not so obvious. Personally, I'd get a new battery while they're offered. YMMV.

    Me, too. Even if your battery is pretty functional, the new one is supposedly built with better quality components and is, well, new. No battery last forever, and the original battery almost certainly less so than the new one. It's a darn good bet that a replacement battery will be working for longer than the original. Especially since the recall didn't happen until most of us don't particularly need lighting, it's kind of a no-brainer to send it off now and get a new replacement.

    Yeah, it's beginning to get lighter out for my 6am commute, so I may go ahead and take the battery to the recycler at some point over the next couple of weeks and use my old Stella while I wait for the replacement.

    A day after I received the letter and logged into the recall website I received an offer from Geoman for a 4.5 "GEOMAN" Brand battery (not the German make) at 20% off which came to $49 or so. The only down sides were
    a) I had to buy it within 2 days and b) Shipping was about $13.90.
    Sounds to me a bit hight especially since USPS costs $6.00 or so for Priority Mail. I "think" the battery could be mailed since all the others ship that way.
    Oh yeah, the sale offer never stated when I would receive it and with that in mind, I passed

    I used my 20% LOYALTY coupon for a MS900 with a Geoman batterry along with some other stuff to get that $100 minium. The shipping was around $15 or something close to that. It seem that shipping is same for small or larger quanity order. The lights and battery shall be here Monday. It will not be my light but for my partners bike.

    My battery/charger was working fine. I got the letter last week, with the earlier sunrise I decided to take care of it right away. I registered online, had my local batteries plus sign the form, and sent it in Mon or Tues. I don't know when I'll see the actual new battery.

    The letter that I received from GeoManGear is dated April 15, 2011. I'm hoping that the battery replacement is not based on the PIN number assigned to me on the letter.

    That letter says the recall size is about 19,500 battery packs and my PIN last 5 digits is in the 18,000 range.

    I ordered my MS light set in 11/09 and my recall PIN was over 32000. I guess those are just random.

    Anyway I read in the FAQ that they will send the new batteries to those who have had the old batteries the longest.

    I'll be sending in my batteries - I have three - in the next day or two. I may use them once or twice, then Summer will arrive in Alaska and it will be light enough to ride 24/7 for a few months before darkness returns. My recollection for best battery life is to put them away 2/3 charged. If correct that's something of a pain in the butt, but that's what I understand is the best practice. Corrections/comments?

    Not that anyone will actually get any answers about other MS battery recalls/defects - you can be sure that Geoman is using first rate legal help in covering their own collective ******. My two-cent detective work took me to these sites.

    Geoman's Battery recall law group - Rust Consulting, Inc

    Geoman's Law firm's public relations fulfillment group Kinsella Media
