FAQ: Frequently Asked Questions

 

Dell XPS 13 9350 — 5K9CP-Compatible 57Wh Battery — FAQ

Is this the right battery for my laptop?
Yes—this pack replaces Dell part 5K9CP for the XPS 13 (9350). It also cross-references common Dell PNs such as 90V7W, JD25G, JHXPY, RWT1R, DIN02, 0N7T6. Always match the code on your original label. 
What are the electrical specs?
57Wh capacity (BTI spec), nominal 7.6V, 4-cell Li-ion design. Many OEM listings for the same family show 56Wh / ~7.6V—both are direct replacements in the 9350. 
Will it also fit other XPS 13 models?
The 5K9CP/90V7W battery family is commonly listed for XPS 13 9343/9350. Check your exact model and original PN to confirm. 
How long is the warranty?
BTI lists an 18-month warranty on this 5K9CP-compatible battery. 
What runtime should I expect?
Runtime varies by workload and settings. A fresh 56–57Wh pack typically delivers several hours of mixed use on the XPS 13 9350; heavy tasks (video, many tabs) reduce this, while light office use extends it. (Vendors quote 56Wh as the OEM capacity reference.) 
Do I need to “calibrate” the battery?
No special break-in is required for Li-ion. After installation, one full charge and a normal discharge can help Windows/macOS learn the new pack more quickly.
Is installation difficult?
The 9350 battery is internal. Remove the bottom cover, disconnect the old pack, and screw in the new one. Use ESD care; if unsure, consult a technician or a step-by-step guide. (Dell’s 9350 reference manual covers battery service.) 
Why do some listings say 7.4V/52Wh and others 7.6V/56–57Wh?
Both are seen across the same battery family/chemistry; nominal voltage reporting and capacity labels vary by manufacturer batch. The 9350 platform is paired with ~7.6V, 56–57Wh 4-cell packs under PNs like 5K9CP/90V7W/JHXPY. 
Safety & transport notes
Use only genuine-spec replacements, avoid puncture/short-circuit, and do not use swollen packs. For flights, carry spare batteries in carry-on luggage per airline guidance (not checked bags).
