Great Battery Replacement for Dell Laptop - Fit Perfectly

I bought this for my Dell Inspiron 15R (a laptop) whose battery was giving me issues. I called Dell and their battery was much more expensive, over $100. Dell said in order for them to assess whether it was a battery issue or not, I would need to send it in for them to figure this out. That cost was probably $150, I don't exactly remember. PLUS, the battery, over $100. I went to Amazon, typed in my laptop's information and I got a number of hits as to what battery would work. I chose Bull-Tech because they had a lot of positive reviews and reviews that helped me. It took me minutes to install into my laptop with ZERO issues. This was over 2 months ago. Hopefully the battery lasts well past when I want to upgrade my laptop. Great price at about $30. After I installed the battery, my error message went away. Didn't cost me shipping my laptop, assessment fee, and battery price of over 3x what I paid for this battery.

Best Cheap Alternative

I'm very satisfied with this battery. My laptop was a Dell Inspiron 15R 5537 and it worked fine with my laptop. My last battery failed for unknown reasons and wouldn't charge. (I'm guessing it was because I kept my laptop plugged in all the time thinking the "desktop mode" dell offered with this computer would keep my battery from going bad, boy was I wrong) Anyway, this battery was the perfect solution for my model laptop. I'm sad to say it didn't work for one other person as seen in the reviews, but it worked for my laptop. I'm glad I got it, and for this price, it was better than ordering a $100 battery from dell themselves. It was the best cheap alternative. So far it's been holding a charge very well and I've had no issues with the battery. It's working just like how my original battery did when this computer was brand new in 2013. I'm glad to have made the purchase!

Great replacement at a great price...

The battery in my Dell 14r laptop had just quit. I found this Bull-Tech replacement on Amazon. BULL-TECH made it easy to select the right one, the price was very reasonable, the shipping was fast, the battery fit perfectly, and I was back in business! I can't really speak definitively to longevity as I've only had it a few weeks... but so far it's been perfect. Just a note: at first I tried ordering one from Dell, which was unnecessarily complicated, almost double the price, plus weeks of shipping time! Sure glad I found this one from Bull-Tech.

Still great battery life even when not unplugged very often

I had previously bought a different battery about a year ago for my old Dell Inspiron laptop and that one did not last very long at all. I tried to run it off the battery more often rather than leaving it plugged in all the time as I'd done with the original battery, but that didn't help and the battery still quickly degraded until it was useless. But this one seems to be holding up very well even though I don't unplug it as often as I should. I just was on a Skype video call for about 30 minutes and even on this pretty power hungry Pentium 5 laptop I got off the call with ~70% battery remaining. I bought it back in July of last year and haven't unplugged it often other than for my weekly Skype call so seems like a pretty solid choice as a replacement battery.

Fits great in DELL Inspiron, works nicely too

I've only had this for a month now, but I can say -- It fit right into my DELL Inspiron - just like it was advertised to do It hold a charge for a long time even when there is a lot of use, it's a 6 cell, not a small 4 or 3 cell (those don't hold the charge very long) For the price, I didn't expect it to be a super long lasting battery, but it's fine (now how long will it keep the long lasting charges over the months to come is anyone's guess, but with the good feedback ratings, and with Amazon telling us this is their choice (or one of them), I felt confident and was not disappointed.

You won't find a better battery than this!

What a relief! This battery lasts all day and now I have the time to do the work I had to stay plugged in to do before. Much better than the one that came with the laptop, highly recommend this battery for the price, fast delivery and quality. Thanks so much for making my pain in the butt laptop a pleasure to use again.

Bull-Tech New Laptop Battery

The Bull-Tech Laptop Battery came just in time. My old battery ran out and I was seeking for a new battery. That's when I came across the Bull-Tech. It was affordable and It was compatible with my Dell Laptop. It's a excellent Laptop battery.

Great Dell battery upgrade or replacement

My original 2 hour battery was down to 1 hour. Now I get 3 hours at a great price. This 65Wh battery housing raises the back of the laptop about 1/4 inch higher than the original 40Wh battery. That makes no difference for me. The battery is an exact and easy fit into my Dell Inspiron 17 3721. The vendor was very good, replacing the first BULL-TECH battery which would not charge in may laptop. The replacement is working very well.

Great replacement battery for my Dell Inspiron

My original battery died and so I ordered this one not really knowing what to expect. It has been very reliable, holds a charge for a long time, and far exceeded my expectations. I am glad I found it and purchased it. It was easy to install, arrived quickly, and shipped quickly. Worth the money!

Good deal, fast delivery

I bought this to replace the battery on my Dell Inspiron 15R-5537, which had gone bad. I placed the order on April 2nd, 2019 and it was delivered the following day, thanks to amazon prime. I have been using the battery since then, and I am writing this review on May 22nd, 2019. -The price was about half what Dell was offering at the time I made the purchase -The battery was easy to install and fits snugly. No wobbling like my previous one. -I get about 5 hours of battery life after full charge. I usually have multiply browser windows opened, with about 50 tabs in some, including YouTube videos. So getting about 5 hours out of a single full charge impresses me. Hopefully the longevity will be as impressive.
