I've been searching for battery replacement for Alienware 17 R3, contacted Dell but it is no longer available, as this model is older than 5 years.

Googlefu lead me to laptopbattery.com.my, but the site rating is so bad, reviews are saying the batteries die fast, with no chance of RMAing the thing.

So I wanna know where do you find trustworthy OEM battery seller?

local shop. at least you get 1 or 3 month of OEM warranty. if want cheaper direct china mall site buy.

you can try this shop https://www.takumiko.com.my/ . I changed my dell 15 inspiron battery from them. the price they quoted compare to official Dell is about 50% cheaper. Yes, they provide me OEM battery with 3 months warranty. The battery is still in good condition until now. It's been working/serving me for 2 years and still counting. My laptop is my daily driver. 8hrs a day, 6days a week. Battery still can run without charging for 5-6hrs of graphic editing usage.

Shopee selling for rm 140, local seller

Its incredibly easy to change the battery, and considering the price, changing after 1 year also worth it.

I kept my AW14 battery disconnected all times unless needed to prolong lifespan.

Already tried searching local shop, no result.

Yeah china got... considering to get from there

Very interesting.... will contact them. Thank you much!

I used BatteryAll at Lazada. They found a battery for my old Thinkpad X61T which is 13 years old. The battery is of high quality too.

Nope.... not this. Also, the battery that I am searching for, is ultra hard to remove. Have to remove the bottom panels and stuffs.
