Rechargeable Batteries - laptop batteries, e1505


Just a little tidbit for everyone using laptop battaries(specifically LI-Ion)



Most battaries that favor a constant charge and recharge capacity work in two different forms. Your standard Ni-Cd or nickel cadmium battery is a slow drain slow charge type battery, a complete drain and recharge is a standard that most of us know. Not the case with Li-Ion, the lithium battery, and newer Metal Hydroxide batteries work better and last longer using the 100-40-100-20-100-40-100-40-100-20% recharge plans. On your initial charge of 100% charging you let the battery drain to 40% and then recharge to 100% and then the second depletion to 20% and back to a full recharge cycle. This helps maintain the battery condition and in some aspects the "Brain" of the battery so to speak is set in motion and maintains battery health througout time.

I myself thought the cycle was complete depleation of the battery on each recharge which actually shortens the life of the battery.(learn something new everyday)



Another item to remember is that when you plug in your laptop, and the indicator says fully charged, the battery is still being used in most cases and recharging. A good note is to remove the battery while in use of a power outlet and set aside until going mobile. This will also help prolong the battery. Hope this helps anyone who may be having to replace batteries often.



(P.S.) also good for cell phone usage (have had my phone for 4 years with no problems in keeping a full charge of battery life for at least 2 days, havent replaced the battery yet)

Hi All,



I have been a great fan of all products and customer reviews provided at amazon. This is the first time that a product that had 17 4+ reviews failed miserably. The battery seems to be not recognized by Dell. Once I put the battery in my Inspiron E1505, on booting the laptop, i get the warning message stating

"Warning:The model number of the primary battery can not be recognized by Dell

The battery would not be charged."



I spent almost 2 hours trying to resolve this issue, upgraded my bios from A03 to A17 but still nothing changes. Either all the 17 4+ reviewers were affiliates of the seller and are bogus or my case is a one of scenario. Whatever be it, I am highly dissatisfied by the product and would appreciate if anyone knows of a valid solution for the 50$ spent on this item.

In spite of Amazon's product title, this battery is not compatible with my Inspiron 1505. The 1505 does not recognize this battery, and it does not charge. Save yourself the aggravation, and avoid this product.

I read all the favorable reviews about this "Laptop Replacement Battery" and bought this product on September 10, 2009. I received it via USPS on September 24th. The battery was about 62% charged when I got it. I have a Dell Inspiron E1505, and I had checked before buying that this battery was compatible with E1505.



Now the problem.



The battery is not recognised by Dell at bootup. I upgraded by bios, with the same result. After the complete charge of the battery was drained out, i have tried charging it, and it does not charge at all.



I think I have been thoroughly duped. I bought this for $51, and I now see that the price has been reduced to $39.



I am going to figure out a way to return this product and get my money back. A complete waste of time, and waste of money.



Save yourself $50 and don't buy this piece of crap.

The laptop battery arrived promptly with USPS priority mail.



I left it charged fully over night for about 6 hours.



It functioned for a full 3 hours before getting down to the 10% recharge level. The usage was heavy 2 hour disk and CD drive work as I was installing web cam software twice as I goofed it up the first time and had to unload the software and load it again. Last hour was email and web usage.



The battery performed better than expected. The battery meter at one point indicated that it had 5+ hours left. I am sure that would be just web usage.



Great deal versus the Dell $150+ price tag.

This battery is compatible and works well with the Vostro 1000. Instructions are confusing. I simply installed and followed good battery practices - completely charged the battery, completely drained the battery, then repeated.

UPDATE: One year later and this battery is still working like a champ! :)



--------------------------------------



I've needed a new battery for my Inspiron E1505 for several months, but just didn't want to bite the bullet and spend nearly $200 buying it from Dell. On a whim, I thought I'd check Amazon. I found this and saw that most reviews were good, so I took a shot.



I've had the battery for a little over a month now and it seems to be working well. I'm very glad I didn't spend the money buying a Dell battery when this one works just as well for 1/4 the price. Even if it doesn't last as long as a manufacturer's battery, it won't be that heart-breaking to lose $50 bucks.



The only VERY MINOR complaint, if you can call it that, is that the indicator lights on the battery itself (showing you how much juice is left when you press the button,) doesn't seem to work. I shaved off one star because of this, but it's really not a big deal to me.

This battery was received as advertised and it's fit and performance was and is as promised. The price was right too. Am using it now as I type this review. It is the same battery with all details except not having the Dell logo on it. - Laptop Battery - Laptop Batteries - Dell Battery - E1505'
