Low battery life
The media could not be loaded. 1. Battery does not charge above 75% 2. When it goes below 50% it suddenly shows 7% and says battery low. 2700 is not the right price for this battery. A duplicate battery of 1200 is more affordable.

Genuine LGC Battery – Good Performance, Slightly Lower Capacity Than Expected
I bought this battery as a replacement for my Dell Inspiron 3521, and so far it's been working well. The system recognizes it as "DELL 49VTP27J", and the manufacturer is LGC (LG Chem), which is a known OEM supplier for Dell, so that’s reassuring.Performance:Full charge capacity is 48,840 mWh, exactly as shown in the battery report.It holds charge well and performs much better than my old degraded battery (~42,000 mWh).No issues with compatibility — plug and play, works seamlessly with Windows.Note:While it's advertised as a 65 Wh battery, the actual full charge capacity is 48.84 Wh. That’s a bit misleading if you're expecting the full 65 Wh performance.No visible branding on the outside, but the system internally identifies it correctly as a Dell-compatible unit.Pros:Likely OEM-quality (manufactured by LGC)Works reliablyGood improvement over my previous batteryCons:Lower actual capacity than advertisedNo clear mention of capacity rating on the physical batteryVerdict:Overall, I’m satisfied with the battery for general daily use. Just keep in mind that while it’s reliable and likely OEM, it doesn't deliver the full 65 Wh as claimed — more like ~49 Wh. Still, a solid and affordable upgrade for older laptops.

Not a genuine battery. very bad quality
The battery health was dropped from 99% to 92% in just 3 days.The charging of battery from 0 to 100 around 3.5.The discharging from 100 to 0 takes around 100 - 120 minutes (<2 hrs.)Overall the battery quality is VERY VERY BADIt is worse than my old battery which at least charged in 2 hours and give up to our backup for 2 hrs

Very bad service
मैने 65 वाट की बैटरी ऑर्डर की पर मुझे40 वाट की बैटरी प्राप्त हुई।फिर मैंने उसे रिप्लेस के लिये डाला तो कहा कि 15 दिन लगेंगे तो मैने उस ऑर्डर को कैंसिल कर के नया ऑर्डर लगाया फिर भी मुझे वो ही बैटरी मिली।amazon से ऐसी सर्विस की उम्मीद नही थी।very bad
