Dell Orignal Battery M5Y1K Inspiron 5558 3458 3558 3551 5558 3451 5758 Vostro 3458 3558 14.6V 2600mAh

This is a good Dell product - at first glance (used over one day). Fully charged battery lasted me 7 hours of work including one ppt preparation, continuous music and heavy internet browsing. Giving 4 stars for VFM as cost is a little high BUT I may be proven wrong if battery lasts for more than 3 years. Old battery (supposedly original) lasted me 2.5 years and cost me Rs. 2,800 however it failed suddenly, leaving me high and dry!! Hope this one functions better. Worth a buy.

FAKE/ Duplicate product.. 1. QR code doesn't work, 2. Poor product finishing 3. Battery lasts only for 20 mins max after full charge, when new only for 30 minutes. 4. Looks like reconditioned article.

Good quality of product

Worth to buy the product initially I thought whether the battery is really compatible with my laptop I have charged for 100% i observed The battery life has been 2.5 hours After watching the videos surfing the internet I am happy that I can say about this product

i would like to apoligise to the seller as in my previous review i told the battery is heavily detoriated old stock i would like clarify after all theese months after the battery has calibrated it self its a flawless battery and is showing excatly same capicity of 41 wh what it should show

As per the specification mentioned on the battery physically, it should be a 40 Wh battery. Original battery which came with Laptop has a design capacity of 41.44 Wh, whereas this new battery is rated at 32.56 Wh as per its design capacity. I verified this using the Windows battery report and compared both values. the new battery has a lower capacity than the battery came with Laptop, it is currently operating at 100% health and it is backing up 5.5 Hrs . Attaching the Screen shot of battery report for reference.

When I received the battery it was 14% charged. While charging, it heated up my laptop. For 100% charge it took an hour and 33 minutes. In the first half an hour itself, the battery was hot. After one and half hour of use it's charging came down to 25%! Again after being charged full it's showing 69%. The moment logged in it's heating up again! Worst battery!!!

I got dell battery for my dell Inspiron 3000 series with good condition and genuine product. It's fit as usual I battery compartment. But after Using from Frist day to till now it's rendomly shutting down it self at 1st day 30-35 percent battery then after at 25-30 percent battery and from 5th day to now at 15-20 percent battery. Nowadays coming that I have to move service centre to fix this issue with replacement of new battery. let's see what happens. (Service centre is so far from my home town) (It should be under 10 to 15 km area especially when ur home town is in well developed areas.) Thanks.
