Are there any independent references on laptop battery performance? I really don't care for the boasts of the laptop manufacturers as their numbers never have much relevance to reality.

I have a Dell latitude D520 with Intel Core 2 T5600 @ 1.83 GHz with 2 Gigs of RAM I've been using it now to surf e-bay, do googling and use this board for 1 hour and the battery meter claims it has 39% remaining. I know this is pretty good; but, how would it compare to an actually new battery? (I got this laptop used a few weeks ago and have replaced its screen and touchpad.)

Since battery life is entirely dependent on the device in which it is used, you'll have to look at either the manufacturer's estimate or other general system reviews. Laptop batteries deteriorate significantly after a few years. About 2 hours sounds reasonable for a 3-year-old standard laptop.

Well, this one just went into standby at 82 minutes with 10% left on the battery meter. I have a Compaq R3000Z for which I recently replaced the battery. (It finally fell to 12 minutes.) When I bought it new, I chose the higher-capacity 6600mAh (over the 4400). It gives me well over two hours with its new 6600, same as when it was new.

The reason I'm asking is that I'm thinking of getting a new battery for the Dell--if I thought it would get me up to 2 hours; but, it would be disappointing to buy a new battery and find I have gained only a very few minutes.

I recently purchased a new battery for my laptop. I searched around and found Laptop Battery Depot where I purchased the battery. Best price for the highest capacity battery they had for my Dell Inspiron 1501. Also found on their site some information you may find useful regarding some procedures one can employ to ensure getting the most out of your battery. Interestingly, first usage and how one goes about it is very important, at least they say it is. It sound logical and reasonable. Anyhow click here to go to the "Battery Care" link on their site. Check it out.:up:
BTW... Free shipping...:D

Thanks for the link. I've been looking for something with higher capacity than this 4400 and haven't been able to find it until I got the clue from you and added the "5200mAh" term to my Google search.

If it is truthful/actual capacity, it is good news.

I also found this 5200mAh battery for $31.75, including shipping on ebay. It's strange to me that almost no one lists the chemistry in their ads. I've got a question in to him now asking about that. If it's lithium ion, I think I'll order.

What else would they be?

I would really be hesitant about purchasing a laptop battery on ebay. Batteries are inherently a piece of hardware that is guaranteed to degrade over time and you have no way of knowing the age, usage or condition of a used battery.

Nickel Cadmium, Nickel Metal Hydride, who knows for sure. I've learned to confirm everything. Even reputable companies like Seagate, Western Digital and IBM have been lying about the size of their hard disks.

I bought a Palm Treo 680 recently, advertised as new, for $200. It was a gray-market import intended for sale in China and it had been unlocked which voided even its Chinese warranty. One would think that being advertised as NEW that it carried the standard one-year US warranty. Not so. I told this to the dealer and he unashamedly stated "it has no manufacturer's warranty and none is mentioned in the ad".

By the way, any product modified by a third party cannot legally be described as new in any of the 50 US.

So, verify everything.

These batteries are advertised as "new" and the seller has 115 thousand sales on e-bay. His positive and neutral feedback is 98.8%. And at this price . . . well, I can't help myself.

The most difficult lie to detect would be a lie about the battery's capacity. That's the only thing I can't verify before the purchase.

To each his own. :) Speaking for myself, I generally adhere to the old adage "If it looks to good to be true, it usually is". I avoid eBay for the same reason I don't frequent Casino's. There are a lot of people who have made a LOT of money on eBay just as Casino's make a LOT of money from people who just can't resist the concept of the "big win". There is a reason for that. Insurance companies (all kinds) have the most lucrative "legitimate" con game going. The world is filled with a certain number of people and companies who spend the vast majority of their time, money and effort devising ways to part the average person from his/her money. They have come up with some real effective methods, some of them even "legitimate".

Laptop batteries are lithium ion. I'm not aware of any model that uses anything else. By definition, the battery would have to be lithium ion if is compatible with that model laptop.

I've not heard of any company lying about the size of hard drives. I have heard, however, of confusion over MB to GB size conversions, but I'd hardly call that lying.

The seller might describe the battery as new meaning it hasn't been used in a computer, but with laptop batteries, that doesn't mean it has its original charging capacity. As stated, they do degrade over time whether used in a laptop or not.

I'm not sure what you're looking for with regards to battery capacity for that laptop, but you're simply not going to get anything outstanding. Even with the slightly higher capacity battery, you might only squeeze an extra hour out of it at best.

Either his feedback score is accurate or he's found a way to scam those numbers. And I just don't see how he could have done the latter.

As for the price, I have a customer who is an importer whose mark-ups are typically 5- to 8 times. It just could be that BatteryMonster is simply a direct importer using less mark-up. With such high sale numbers on e-bay, it wouldn't make sense not to directly import.

I've seen some items on e-bay that if I wanted to buy direct from China in 1000 lots, I can get them for less that 10% of the lowest selling price on e-bay. So it is entirely possible BatteryMonster's prices aren't entirely too good to be true.

Then there's the possibility it could explode so I guess there's more than the $32 at risk.
