At some point in your laptop’s life, the battery will get worse and worse until it stops working. On the forums this week, a user asked for help finding the best battery replacement when that scary day comes: “I have a Dell Inspiron 15R 5537 laptop and need a new battery. Dell told me [battery] is 65W 6 cells. Suggestions?”
Well, you’ve actually done most of the work already. You know the model as well as the type of battery inside the laptop. After digging around a bit, I discovered that you can purchase a spare battery from Dell itself. This is a $ 58 11.1V, 65Wh Primary Li-ion battery that is marked compatible with your Inspiron 15R 5537. For reference, WHr (watt hours) corresponds to the capacity of the battery, so more is better.
There is also a cheaper model on Aliexpress for $ 29.99. However, we cannot vouch for this battery because we have not tested it. It’s safer to recommend buying from the company that sold you the laptop.
How to hunt for batteries
In our customer’s case, I went straight to the Dell support site and typed in the laptop’s service tag, which you can find on the back / bottom of the case (there is also an option to automatically detect your PC). Once you’re in, just go to the Parts & Accessories section and then to Batteries. In this case, two batteries appeared, so you just picked a battery that’s larger in your price range.
Other laptop companies may have similar systems installed, but if you don’t have one, you should call the manufacturer directly and see if you can coordinate purchasing a battery from them. If they don’t sell a battery, ask them about WHr, cell count and voltage of the one you have.
Then enter those numbers into Google (or your search engine / online store of choice) and make sure that, depending on which battery you come across, the exact names of the laptops it is compatible with are listed. On the website zeto.ua you can choose your laptop model and find the right battery of good quality.
Finally, if you suspect that your battery won’t last that long, I suggest buying a replacement as soon as you receive your new laptop. This way you don’t have to scramble around once it’s time to make the exchange.
