This product is as good as any other one that would cost a lot more. I'm glad that I ordered this.

Straight out of the package it was at 45% charged and it held its charge a longer than I realized, but I was little worried after i first installed it because it did not appear to charging. I left my computer on the charger all night and the next day when I turned it on, it had not charged. I left battery run down completely until my computer died, then I put it on the charger again and the next morning it was fully charged. I ran all of my normal programs and functions (2 hours/ daily) for 3 days off of a fully charged battery.

Good

Upon delivery, I installed this battery and charged it for 48 hours with PC off. When booting up, the battery would charge to 70% max. I went off battery for 90 minutes until the percentage dropped into the forties. Plugged it back in to charge and the battery only charged to 70%. Repeated process three times. Took the battery in to the shop (with other required service) and explained the issue. They got it to charge to 100% but when I used it again, ran it down to 20%, battery would only charge again to 70%. Now, it will not take a charge and percentage keeps dropping when off the power chord. My first impression was the battery is old stock. I know it's not my laptop as I recently invested $650.00 in upgrades. These batteries are not that expensive, am considering buying another one. I would prefer a replacement. -KenUPDATE: SOLICE CAME THROUGH! I contacted SOLICE to request that my bad battery be replaced; even though I had exceeded my return date by 22 days. Pete, the company owner, emailed me back promptly and provided a positive response. SOLICE forwarded me a new battery in less than 2 days, I have installed it and it is working perfectly. Thanks Pete for coming through. Highly recommend SOLICE for your computer battery needs. They've proven to me that they backup their products, and deal honestly with customers!

The battery is the third replacement in my wife's Dell Inspiron 15-3541 quad core AMD that is five years old, upgraded to 8GB of memory and an 500 GB SSD. Its performance so far has been very impressive.Shortly after installing the Solice battery the video cable to the screen shorted out (it's been opened and closed at least 5000 times over the years and shorted inside the hinge). In the three weeks it's taken me to replace the cable I've gotten two or more emails from the vendor KAQIAR INC that were titled "Additional information required". Sounds like they are giving me homework or had become my boss.The Solice has been delivering over 3.5 hours per full charge, with constant wifi traffic and full screen video. If this keeps up it will have been the best of all batteries in this laptop (even the original Dell). It fits exactly in the battery bay and makes snug connections with the laptop's copper tabs. No loose shaking or rattling, as some of its predecessors had.The battery is a great deal in today's market with other vendors selling lousy batteries with hype and fake review campaigns. If Kaqiar Inc. can take a breath and let the customers use the product for a month or two before demanding a review it would be the perfect buy.

Bought this to replace a 5 year old battery in a Dell Inspiron 3537. The old battery would hold a charge for 50-70 minutes. I installed this new battery today, let it charge to 100% (it was at 69% out of the box). So far, the laptop has been running off the battery for almost two hours and it's at 75%, and it says it has another 3 hours to go. I am pleased...the old battery would have died an hour ago. I looked at Dell's website first, but when I saw the cost, I checked amazon and the price was less than half of what Dell charged. Maybe there is a difference, although these batteries are all made in China. Removing the old battery and installing the new one was an easy process, less than 5 minutes. So time will tell, but so far, I am impressed and this battery is performing very well.

The battery was exactly what I ordered, it arrived quickly and at a great price.

UPDATE 2: Well, I jumped the gun when I posted my first update. The original problem has returned (see below). IMO, if I turn off the computer at night with the battery charged at 100% it should not lose 10% of its charge just sitting overnight.UPDATE 1: After doing a search in the questions section on Amazon I found this advice from the seller: drain battery to 1% then full re-charge. Repeat process. I re-charged with the computer off. After doing this I noticed that the battery is holding its charge much better. Would have been nice if this tip had been included with the battery. Or maybe it was. I don't remember seeing any instructions or troubleshooting tips. Anyway, changing my rating from 2 to 4 stars.______________________________________________________________________________I purchased this for my Dell Inspiron 15 Model 3537 and installed it June 2019. About a month or so ago this is what I noticed: After shutting down the computer for the night with a 100% charge and leaving it unplugged, I turned it on next morning and noticed the battery reading 90% charged. This has been consistent since i first noticed the problem. This evening I turned it on after not using the computer for about 22 hours and the charge read 88%. Based on this, I am not confident that this battery will last nearly as long as the original Dell battery which was 5 years old when I replaced it - and it still had life in it.
