questionsis it worth the risk to buy cheap ebay laptop…


I prefer OEM. Bought a non OEM cell phone battery one time that swelled when it was being charged in a wall charger and cracked the charger. Lucky I had bought it as a spare and not installed in my phone first. I think you are paying for some quality control with an OEM. For a non OEM who makes batteries to fit thousands of devices there is less incentive to care about defects or if the battery meets OEM specs.


Go read some of the reviews on Amazon for the cheap batteries, not just laptops but cell phones and cameras - it really isn't worth the risk. You're going to get a used battery that is likely just as crappy as the one you're looking to replace.

What type of laptop do you have? There are lots of folks here really good at ferreting out deals on stuff....

BTW - I don't mean to imply that all replacement batteries are as bad as you might get with the cheap eBay batteries. There are some quality third party batteries to be had at a discount.


Beyond the risk of fire is the risk of not getting a good quality product and the risk of losing your product warranty. Most of the time you'll be fine to go with another manufacturer but it's a significant risk.


I buy replacement batteries for my cordless tools all the time. A battery is not a complicated thing. I deal with the same person for most of my batteries. Once you rip apart the case of a battery you will see that the big battereis are just a series of c or d cell batteries. If paying more gives you piece of mind, then go ahead. Sometimes you can't buy respiffed batteries and have to deal with paying more from a manufacturer - like my hitachi. They switch their battery cases so often so aftermarket people cant dip into their profits.

If you can find a respiffed laptop battery at a fraction of the cost, why not try it?

Marketing is the main difference between a standard duracell, energizer, and generic version (same type alkaline).


I buy replacement batteries on eBay for my older laptops and have had no issues. You just need to buy from a large reputable dealer on eBay, one with +99% rating and thousands of deals. Most are based in California but the products come from China.


If it is an older notebook there is no reason to buy an overpriced OEM battery for equipment that might not even be worth the cost of the battery.

I buy from places with a long standing positive history and a guarantee and save a lot. Greatly extending the life of a machine that would otherwise be worthless.


Thank you for all the input everyone.


@ecriscit: Sorry, not all batteries are created equal.

I am an electronics technician and have been dealing with battery packs for computers, cell phones, and two-way radios for many years. The major difference in batteries is quality, not just in the cell manufacturing but in the production of the actual battery pack itself. OEM (called branded in my world) tend to have better quality components and last longer. Aftermarket batteries come in a wide array of qualities, you can get good ones and then you can get bad ones. Trial and error is the only way to tell the difference in an aftermarket battery. Just make sure that you check the warranty offered and have your battery checked before the warranty period is up. I am not even going into the differences between re-chargable battery types. Just remember to dispose of them properly when they are dead (a lot of battery stores and two-way radio shops offer free recycling).


I've had horrible luck with cheap batteries. I have yet to buy one that works. If you have descent soldering skills, you might want to look up a few battery repair videos.


I've had similar luck with OEM and 3rd party. My OEM laptop battery had lasted ~1 year before it started to fail. I would say that if the 3rd party battery costs less than half as much as the OEM battery, go for it. I tend to use amazon to pick up 3rd party batteries, some even come with (questionable) 1 year warranties. Just make sure it lists your specific model and that the voltage(V) and capacity(mAh) are the same (actually the capacity can vary a bit, but you probably wouldn't want to get a battery if its listed voltage is even .5V off from yours.

The big thing is to check the reviews of the seller, as well as the specs on the battery and the reviews to make sure that you get the right product and can return it if it doesn't work correctly (if it gives you inadequate charge time you can return it right away and say that it didn't fit... Make sure you drain the battery before shipping, I seem to remember something about not being able to ship charged batteries or some such..)


@ecriscit: That's true, batteries are usually pretty simple and pretty similar. One of the big problems though is the quality of materials and manufacturing. A lot of that kinda stuff is made in China - and I know this might be a little tough to believe at first, but there are some places in China that don't always produce products up to standards - seriously, you can look it up :D

I'm kinda bitter though...I'm dealing with a company trying to screw me over on a bunk battery right now heh...

Anyways...I'll jump on the OEM bandwagon. OEM if you can afford it. Like anything though, I'm sure there are some great 3rd party battery companies. BUT, for every good one, there are probably 50 that suck..

Just ignore that crap ^. Just stating the obvious lol...

@theoneill555 nailed it


Even checking the feedback for the seller didn't stop me from ending up with 3 counterfeits (sold as OEM). Have to realize that a lot of the people giving feedback/buying don't even realize there is a difference between OEM and non-OEM.


I've tried both the aftermarket and used OEM...
Aftermarket didn't fit correctly and were replaced under guaranty but didn't last more than a few months...
Ended up purchasing 2 used OEM that had tested as good and I haven't had any problems with them...

I use cheap $3 aftermarket db-l80 batteries for my Sanyo camcorder and they don't last quite as long as OEM, but they are only $3 each! I'm not going to pay $10 for something that's only slightly better.
The $3 aftermarket batteries, at least the db-l80 ones I've bought, do have protection against deep discharge and overcharging of the lithium cell. If you rip it apart, right behind the 3 contact (+, - and case gnd), there is a small circuit board with a MOSFET that provides the protection.

Again this is the cheapest stuff you can get, right from the 'sort by lowest price' on Ebay or Amazon.
