    So I just got this in the mail today. I was wondering, would it be bad to leave a spare battery in there charging all the time, or should I take it out everyday and charge it as needed? I want to be able to have a fully charged spare at any given time.

    Thanks!

    PS: With either 1750 Seidio or stock HTC battery.

    Ahh good question. I have the same issue. I bought a USB to USB cable and have it in my car, which is throwing a charge 24/7 to my stock. Seems to be conflicting reports on it this is good or bad. I know on my POS Sony laptop, which has not been of charge in about 3 years (LOL) will drain the battery off in about 10 mins.

    Well I guess worst case scenario, I kill the stock battery and not my extended life battery. I'd rather kill the less powerful one. So what the hell? I'll leave it on the charger, see what happens. I guess I can always buy another Seidio if I need it.

    What are you guys talking about? Charge the battery in the external and either leave it there or pull it out for whenever you need it. It will not overcharge or lose it's charge if it sits in the drawer for a month or so.

    Huh? Wait a second.

    This is confusing, but here is what I think.

    1. Charge it , then pull it off the charger when its done.

    We have no idea if the battery charger continues to check the charge status and charges, we have no idea when the battery charger decided its done charging and then continues to do its "top off" charge (during green light its done or after).

    I might suggest charge it till its done and then store it and then place it back on charge a few days later if you never used it.

    I am referring to leaving the battery on charge, all the time.

    Lithium Ion batteries do not work like this. They are not car batteries. I would 99.9% guarantee you that once the charge cycle is finished, it will not reset to charge again until the battery is pulled out or power is cycled to the charger.

    Yes, you're just wasting some power to power the charger, essentially, pulling it out and leaving it on the shelf is the safest thing... It's not going get charged anymore after it goes green (for done charged) - so you might as well pull it.

    Exactly.. You are just wasting power at that point. And exposing your charger to the potential of a power spike if you live in thunderstorm prone areas like me..

    However, if the power goes off and on, it will top off your battery if it has managed to self-discharge any at that point. I find that these plymer batts hold a charge for many weeks before they go down enough to take a significant charge.. Good ones that is...

    I bought some crappy ones on ebay that would go dead on their own in two days...

    To test this your self. Fully charge a battery and pull it out of the charger. Do not use it for a week and put it back in. See how long the charger stays in charge mode. With HQ batts, it will only do so for a few seconds..

    Temperature of the environment/battery will impact the results - just be aware of that.

    Coming from the world of electric RC. I know a good amount about lipo batteries. I'm pretty sure thats what these are. If they behave the same way as my RC batteries do, once fully charged, you can take it off the charger and it will loose very little charge over time.

    One problem I see with leaving the battery in the charger, is that if it keeps re-peaking the battery. If you plan to store the battery, basically not use it for a while, it is best to keep it at about 75-80% charge. Then re-peak right before using.

    TBH taking it to 100% and letting it sit for a long time will not do much damage but making it stay at 100& without going down at all COULD be, I just don't have much experience with that issue because when my batteries are 100%, I'm mobbin my RC! :D

    The real killer with lipo batteries is letting them drop too low I believe 1.7V is the danger zone(per cell). My biggest question is, do these devices that use lipo batteries have some sort of cut off to stop the battery from going too low? I've always wondered but never looked into it.:confused:

    If these are not lipo batteries, disregard my post, lol

    Thanks all you guys for your advice. I think, at least for now, I'm going to leave it on the charger. I have the tendency to lose stuff like this if I take it out and store it. Like I said before, worst case scenario I kill the stock battery and I have to buy another one. At least I have the extended battery to hold me over, and honestly with that battery I haven't had to use the stock one yet. I just want to have the option in case I know my phone will be off the charger for a couple days (camping or accidentally leaving the phone off the charger with no time to charge it fully). Appreciate the advice, though. If I notice any problems with the stock battery when I do use it, I'll post them here.

    I don't think you'll have a problem but you should pull it out of the socket. Stick it on the wall if you need but no reason to leave it plugged in. Or just find a drawer that you *know* will always have the battery spare. I have left it for a couple of weeks and then charged it again to top it off. It didn't take any charge meaning nothing was lost. I do swap out the batteries just to keep a rotation thing going. Figure I will get twice as long usage with my 2 OEMs.

    Yeah, maybe I'll swap the battery every week or so just to keep a rotation going as well. I am seeing now that I assume I've went through the charging cycle of the 1750 battery that the stock battery was lasting almost as long. I'm getting about 12 hours with moderate use out of the 1750. I may get a bit less with the stock battery but for what I do with the phone it doesn't make much of a difference which battery I use. I always have a charger nearby. I make sure I do just because the last thing I need is the phone dying in the middle of the day.
