Fancy Buying RJ40G Laptop Battery for Dell Latitude 14 5420 Latitude 15 5520 Precision 15 3560 Series Laptop 01K2CF 075X16 WY9DX P137G P137G001 P104F P104F001 0WK3F1 0M3KCN 005R42 F3T9T 7RV10

Battery cane quick, charges up real fast and works and lasts a long time

It resolved my blinking orange battery light. I discharged it to 2% as directed and then did a full charge. I haven’t tested full battery life but it definitely lasts long enough to do what I need it for. Walk over to the printer or look something up really quick.

WORKS GREAT! First battery I ordered only lasted about 1/2 hour. I contacted the seller and communicated with Emma . She took care of the issue and sent me another GREAT BATTERY now lasts OVER 1hour before needing recharging. Don't be afraid to deal with this company. They stand behind their product and respond QUICKLY.

First battery was wrong but no big. Wasn't a problem returning it. Second battery was perfect. Cept for the fact it wouldn't recognize the battery. At first. Make sure you update your bios prior to install. Thank you.

Replacement battery is next to worthless. It charges to 100% but discharges to less than 10% of total within 55 minutes on power save mode once unplugged and with no programs running. Sad! Even when considering its cheap price, it’s not worth the money.

Great value for the money. Thanks.

This review is written about this product as sold by "Fancy Buying". I don't know if this Amazon listing is for their battery specifically, or a generic one that many sellers sell from, the battery had no identifying marks for the manufacturer/seller. The packaging for the battery itself is pretty poor - just a piece of thin foam wrapped around the bare battery and held in place by packing tape. No box, no nothing. The foam didn't even cover the ends of the battery, leaving packing tape goo on it after removal. Every other battery I have ever purchased has come in a small box with padding all the way around, and usually a small instruction booklet (though that's honestly not necessary in my book). Due to this, the battery was slightly bent when it arrived, which could easily happen with all but the very best shipping packaging, and maybe even then.I know lithium ion batteries can be somewhat fragile, so that concerns me, thus my less-than-stellar review. Seems to be working fine so far, we'll see what happens given a little time, hopefully there was no harm done to the battery.

UPDATE-- The Fancy Buying seller is a good seller, they worked with me and made things right.Original review:Battery came charged to 57%. I put it in but the laptop wouldn't charge it. As the instructions say, I let it discharge. The laptop hibernates at 5%, so I left it on watching a live YouTube stream. Later, after the laptop turned off, I plugged it in and powered up. I expected to see the battery charging indicator, but I didn't, it won't even attempt to charge the battery, says 0%. Now I have a brick. I'll try to return this brick and find a different brand battery.
