Question: if I have a 4 cell battery now will the 6 cell fit?
Document: appears to fit and work fine. Noted a charge by the computer gets it back to 100% charged in about an hour. The charge lasted about 2 hours. I ordered an adapter with the battery and it shows shipped but from a different supplier and it has not arrived. It stays charged when plugged in contrary to the old on which produced a warning to replDell Inspiron 1525/1545 Laptop Battery - Premium TechFuel 6-cell, Li-ion Batteryace the battery.
We recently ordered 2 new batteries for my Dell Inspiron 1545 and for my wife's identical laptop which are now both 4 years old and won't hold a charge. We received the replacements promptly. They fit perfectly and after a recommended 6-8 hour initial charge perform like new. Thank you. Really good value and service.
Awesome battery for the fraction of the price a of a Dell 6 cell battery, I definitely recommend this battery it's awesome!
My Dell is my favorite laptop and this premium TechFuel 6-cell battery breathed life back into my laptop and at a great price too!
Dell Inspiron 1545 Laptop Battery - Premium TechFuel 6-cell, Li-ion Batteryby TechFuelI hate this product it does not works. My laptop will not turn on with this battery attached.
I got this battery and it worked great gave me about 4 hours of good use when I first received it. After about 3 months I realized that the battery life was decreasing greatly over a small period of time. After about 6 months I could get maybe an hour out of it and now at 8 month I can get about 35 minutes from it, and it is telling me that my battery needs to be replaced.
When I originally got this I was so excited because it was cheap and fit my laptop and WORKED!! About a month a go it failed to keep a charge and will not charge any more. So basically it did not last 6 months. I have to be plugged in somewhere for my laptop to work.....inconvenient.
This battery fit my Inspiron 1545 and has been working fine since installation. Probably going on 4 months now and my wife uses her laptop almost constantly.
This battery is good for short term use but I wouldnt depend on it for more than 6 months.
the only thing is I'm very impatient and this battery recommends overnight charge before use. I made it 6 hours :/User error not seller or product.
Answer: Carol, the batteries are the same with the exception the 6 cell may stick out under the laptop providing additional lift for the laptop and better air flow or stick out the back slightly. otherwise work just like the original.
