Great battery very fast delivery

This battery was the exact match for my Dell laptop. I am amazed how great it works and fits. I have not had any problems or only had to charge it once. Very durable and compatibility is great. Now I can take my laptop around with out being attached to a cord.

Seems to work perfectly, had a little trouble getting the right lock to engage and hold the battery in at first but I just kept trying to lay it in and it eventually locked correctly.

So i ordered this on July 3rd and after a few delays i finally got it on July 15th.. Id like to state that this in no way or means is the fault of the seller. Anyway the battery came neatly and securely packaged and was a breeze to install on my Dell Inspiron 15 3537 computer. The battery was flawless and powered up my laptop after months without a battery. I would like to also state the seller had contacted me by email (before the battery arrived, to see how it worked out and to offer any assistance if needed, which is a pleasant surprise and was much appreciated). I would recommend this Seller TCORE for battery replacement if anyone needs it. They are in my opinion one of the best out there. UPDATED REVIEW- After a few months of solid use this battery is no longer working, the funny thing is my computer is telling me that the battery is healthy and has a full charge but when I unplug it from my computer it shuts down. I've tried everything possible to remedy the situation but I get the same result, I've was going to contact the seller but it's already past the return window. So my suggestion is to go buy a genuine Dell battery from the manufacturer and skip this product

Great replacement battery for the price. Pay attention to the directions. This battery came out of the package with 60% charge. In my Dell Inspiron laptop, the battery wouldn't charge it. The battery needed to be calibrated...meaning use it normally (unplugged) and allow the battery to discharge down to about 5%...then plug it up and allow it to charge to 100%. After that, it was good to go.

Works great

Battery fully charges in about one hour and holds a charge for 2 days, even if i stream a movie. i run it until the red light comes on at 7-10% remaining power and it is recharged in no time. So simple to install, even an old fart like me could do it. EXTRA glad the new battery doesn't cost as much as a new laptop, like they did in the olden days. VERY pleased with the quality and price.

Fit and functioned as original. Went by direction to charge. I got about 4 hours run time before computer would shut down. After using for about a month now I get about 3 hours run time before computer tells me I need to charge. The original battery after 8 years still gave me about a year 1.5 hours run time. Only time will tell how this battery does after a year.

Battery is same size and sape. Let's see how many hours will work.

Encaixou e funciona perfeitamente. Espero que dure!

Funktioniert einwandfrei. Eingebaut, eingeschaltet, läuft 👍🏻 Kam mit 55% Akkuladung.

Excellent goods

Commandé en remplacement d'une batterie d'origine Dell XCMRD pour un Inspiron 3531 Le test interne du PC (via F12 au démarrage) indique une bonne capacité estimée à 45 Wh (2.703A x 16,671V) Il faudra voir dans le temps car la batterie est un peu plus légère que celle d'origine... L'originale Dell est fabriquée en Corée et possède des accumulateurs Samsung ICR18650-28A La différence de poids est souvent liée à la densité énergétique des accumulateurs... Chez Dell, le BMS et les connexions internes sont déjà réduites à leur plus simple expression, ce qui confirmera probablement ce point. Il faudra donc voir la tenue dans le temps ; j'essaierai de compléter d'ici quelques mois
