Has anyone else tried the Mugen extended battery?

    I just received mine yesterday and... Nothing! :mad: I charged it in the phone for over 14 hours overnight. It was just DOA. I got it from Mugen's website via Google checkout. It was $43.00+ 11 for shipping! I just emailed about a refund.

    Has anyone else tried this battery? If so, did it work for your Optimus?
    Are there any suggestions on which, if any, extended batteries that do work.(1800 mAh)?

    Haven't tried that one, but some of us ordered batteries from an E Bay seller called HK plaza here: Q576 2X Battery+Charger USB/AC FOR LG Optimus T P509 | eBay
    For $12 you get TWO batteries and a stand alone charger. The batteries fit my phone just like the OEM and give the same battery life.

    Be aware the batteries from HK plaza do not have temperature sensing in them, FWIW.

    Temperature sensors are IMPORTANT for Li tech batteries as Li based batteries can VERY EASILY go into thermal runaway -> burn/explode.

    Remember all those exploding notebooks several years back with the faulty batteries? The PSPs with cheap chinese batteries going up in flames? Apple's first attempt at using Li-ion batteries in their notebooks?

    (They decided to stick with NiMH after a prototype went up in flames...)

    Lithium batteries are just plain touchy... and are one of the items that actually deserve the overzealous manufacturer warnings...

    Hence why I would only use OEM or high quality 3rd party Batteries in a mobile phone. Especially for people who leave them charging overnight..sometimes in an unoccupied room.

    The prices of the OEM LG batteries will only come down as time passes. I think right now they are in the $15 range on eBay for new OEM.

    I've been using two of the cheap china ebay batteries for two months now, and no problems whatsoever.

    Except they don't monitor the temp. I have two of the ArcSoft brand name batteries and they always show 67 degrees no matter what. The OEM temp varies with use. Other than that they seem ok.

    I just ordered an OEM from Amazon. Keep your fingers crossed for me!

    What batteries are those, exactly? (The problem is that

    I bought the same, from that seller ufo111 in your link, and after almost three months of use, comparing those two batteries to three OEMs, I would estimate that the eBay batteries give me 75-80% of the life of the OEMs. On any day when I'm surprised by the battery life, it's always been because I made a mistake as to which was in my phone. In other words, it's sometimes a blind test, but always the same result. Albeit seat-of-the-pants estimating, not controlled testing.

    Maybe you got better batteries. But I just wanted to make it known that there are other estimates (we can't call them "results"). I've seen another give something like a 70% or 75% estimate.

    Having said that, I'm still glad I bought them, as that battery-only charger is the only known one that takes these exact batteries (there are other battery-only chargers where you align pins to contacts, much more tedious and worrisome).

    I would not recommend buying the cheap china batteries,as your safety should come first,remember batteries can be bomb's and when it explodes in your face who are you going to blame,i can see going cheap on chargers,cover and car holders, but not something that can injure you or compromise the safety of the phone.

    OK, I'll take the advice about only going with LG OEM batteries. worth the extra $5 for sure. but what about an external charger? the cheap china ones come with a charger so you can charge up a 2nd battery outside of the phone. the OEM batteries don't come with one of these. I'd really like to be able to charge externally, but I don't want to kill my battery with cheap hardware.
