I purchased two of these BH5X batteries from seller ACC Stop at Amazon.com. Both batteries seemed to be a genuine Motorola battery with an authentic holographic label and are rated for a 1500/1540 (min/typ) mAh capacity. However, I'm not sure that they were really "new" as claimed by the seller because: (1) the contacts seemed to indicate that the batteries had been used, and (2) one battery arrived with a 60% charge while the other arrived fully drained (0% charge).
Is this important? Some sellers would like you to believe that it is not but this is patently false. Lithium Ion batteries have a limited life. Three things cause them to deteriorate: (1) recharge cycles, (2) age, and (3) heat.
Li-ion batteries can be recharged from 400 to 1200 times as long as they are not subjected to too much heat. Some manufacturers claim their Li-ion batteries can be cycled more than 1200 times but this is usually wishfull thinking under "optimum" conditions---500 cycles is probably more typical. If you buy used batteries, they may still perform "like new" but they may have lost half of their life or more, depending on how many times they've been charged. This means that there is definitely value in getting a new battery instead of a used one.
Even if they are not cycled often, Li-ion batteries will naturally deteriorate with age---this is true even if they are left on the shelf and never used. One of the batteries I received was dated 03-Nov-2010. The other was dated 04-Nov-2010. So they were about 5 months old when I received them. This should be fine. By the way, I purchased my Droid X in early March 2011 and the battery that came with it is dated 27-Dec-2010.
The greatest "enemy" of Li-ion batteries is heat. It will reduce their life faster than anything else. This is yet another reason why a new battery is better because you never know how much heat a used battery has been exposed to.
Both of the batteries I received tested well. I tested their recharge rate from 0% to 100% and both batteries charged at a normal rate (approximately 10% per 13 minutes). One battery reached a full (100%) charge in 2 hours 9 minutes and the other reached full charge in 2 hours 17 minutes. This test was done in my Droid X using the stock Motorola AC charging adapter with the phone turned off. I plotted their rate of charge during the test and they matched a known good battery. I also monitored their temperature and they remained cool during charging.
Here's the charging rate of one of the batteries:
0% - start charging
5% - 2 min
10% - 7 min
15% - 6 min
20% - 6 min
30% - 11 min
40% - 12 min
50% - 13 min
60% - 13 min
70% - 12 min
80% - 12 min
90% - 14 min
100% - 21 min
-----------------------------
Total Time: 2 hours 9 minutes
My test of their discharge rate was a bit more subjective: I turned off the display "screen timeout" and played a video until the phone died. Both batteries seemed to last about the same time as my original battery.
Overall, I'm happy with the batteries I received from seller ACC Stop---even if they are used, their price was less than 1/4 the price of new batteries from Verizon or Motorola. However, I wish there was a way to confirm whether the seller's claim of "new" is true. There are many sellers who are selling rejects and heavily used batteries while claiming they are "like new" which makes it difficult on us buyers.
The only negative I can cite was the shipping package. ACC Stop shipped both batteries in a single cardboard envelope with no padding of any kind. I would have preferred them to have been padded---fortunately, they arrived okay.
I have no experience with other sellers of these batteries but I've read of many problems. So if you are not buying your batteries from a reputable source, then you are taking a chance.
I hope my comments are helpful. This Battery is 1500 mAh.
Mr. Brady couldn't have said it any better, caveat emptor buyer beware. It is obvious that something is up with these batteries, but i ordered it anyway because it couldn't hurt for that price. Any reputable dealer will charge anywhere from $45 to $50 for this battery. Even off-name batteries for the droid x are priced similarly. These are not even half the price, the seller varies the price regularly as these batteries have been priced from as little as $2.51 to $24.14. They are definitely not new and the seller has gotten complacent enough on amazon that they don't bother to remove the inspector sticker that says "New Breed Corp. PASS". This is the company that purchases the batteries from the cell phone carriers. They are probably returns. The battery i received works and appears to be fine but was obviously not new. The seller ships first class mail but clearly doesn't drop it in the mail fast enough took a very long time before i received my battery.
Ordered 2 of these I was not sure what I would get. I know that counterfits don't charge in a droid X and also don't show remaining capacity but the 2 batteries I got were the real deal and not only work perfect but their labeling shows they are genuine motorola batteries. The capacity of each battery is also fine. I keep one fully charged in my wallet and another in my backpack. At this price everybody should have a few backups to ensure their X never leaves them stranded with a drained battery. I'm buying 2 more.
My DroidX apparently requires an original equipment manufacturer (OEM) battery. (Unfortunately, this is not the forum to debate the merits or legality of not being able to use after-market or third-party replacements parts in items I have purchased). The battery I received was not accepted by my DroidX. After installing it, I got an error message that indicated that it was not an OEM Motorola battery. This battery looked authentic, complete with holographic sticker and all, but still would not work. I did notice that it came in a plain shipper, wrapped only in plastic, with no "official" looking packaging or clamshell. And perhaps the $6.70 price tag should have caused me to raise an eyebrow, considering replacement BH5X batteries through Verizon are $39.00 (another rip-off). I have also learned to be very careful when shopping on Amazon and to watch for "OEM Equivalent" vs. "OEM", but this item clearly says "New Motorola OEM...". This item was shipped by Amazon, and I returned this directly to Amazon with a note that perhaps they should check to see if it is counterfeit and/or check their supplier. - Droid - Motorola - Battery - Android'
