Best answer: The best place to buy a new battery for your Dell Inspiron 15 7000 is at Amazon. There you can find a 42Wh WDX0R replacement at a reasonable price complete with 12-month warranty and 30-day money-back guarantee.
Which battery does the FHD Inspiron 15 7000 use?
The 1080p (FHD) models of the Dell Inspiron 15 7000 (7570 and 7580) use a 42Wh lithium-ion battery with the type code WDX0R. It operates at 11.4V. You can expect to get between five and seven hours of life from this battery during regular usage.
Dell does not offer replacement batteries straight from their website, so third-party options are often necessary. You might be able to find a Dell-branded battery on eBay, but you'll often get a limited or missing warranty, or an extended delivery time (sometimes up to two or three months).
Amazon offers Prime free shipping (four to five days) on this battery, and it includes a 12-month warranty with a 30-day money-back guarantee on top of that.
What about a 56Wh battery for the 4K Inspiron 15 7570?
The 4K models of the Inspiron 15 7000 (7570) use a larger 56Wh battery that provides a bit more juice for the higher-res touch display and discrete GPU. Unfortunately, Dell doesn't offer replacements straight from their website, and it's nigh impossible to find the proper model from third-party retailers.
If you must replace the battery in your 4K Inspiron 15 7570, your best bet is to use the smaller 42Wh option from JIAZIJIA we have listed here.
How hard is it to replace the battery?
Dell makes it relatively easy to replace the battery in the Inspiron 15 7000. There are ten Phillips-head screws on the bottom of the laptop that, when removed, allow the bottom panel to be removed.
Once inside, there are four more screws that hold the battery in place. Undo them, unclip the battery, and reverse the process with the new replacement battery. Everything should line right up, and the entire process should take between five and 10 minutes.
Change the battery for better life
If the battery in your Inspiron 15 7000 has worn down to the point where a replacement makes sense, the $50 cost will be well worth it.
