My wife's Dell E740 wouldn't turn on without the power supply. Her battery was long gone. I took a shot based on the positive reviews here and I'm very happy. I'm not sure if this is an "extended" battery, or what battery was in my wife's laptop, but this replacement battery is much wider. It takes up quite a bit more space than the one it replaced, but all of the screw holes were in the right place and it fit perfectly. I'm not sure how much battery life she's getting in terms of hours, but it lasts a long, long time. Quick shipping, easy installation after watching a single YouTube video, and a great value.

Glad Amazon had this battery available, as the actual company's price for it is much higher. I had an overblown battery and had to replace it as soon as possible since everything is done online now! Was super easy to install and computer was working straight away. Battery life is very long now. Would definitely recommend if need to replace your battery with a compatible computer model.

The battery is what it says -- genuine-looking part, fits perfectly, and I'm back up to over 3hrs (pretty heavy use, on VPN, 25% screen brightness normally).IMPORTANT: The Dell battery cable that's already installed in the laptop motherboard, and the connector on the battery, are all VERY flimsy, and it's very easy to either rip out or jam-in the connector on the new battery. It's a very tight space, but try to find a way to hold the battery-side connector firmly in place while you press in the connector, ensuring you're lined up correctly.Do the "ultimate test" of whether or not you connected things firmly/correctly by simply unplugging the main laptop power while the system is running (no apps/data open, "settled" post-boot).Oh, and as with any computer upgrades: be careful that you don't lose any laptop screws. They're tiny and like to bounce, so use a proper, well-lit work surface for these tasks. It's an easy upgrade, but requires more care than full-size PC parts.(Currently unplugged, finally without fear of the old dying battery.)[update after 2 weeks of daily usage]Still no problems, and I can go multiple hours unplugged at heavy usage. Been unplugged for over an hour right now, moderate workload + a music stream, and I'm at 84%. Traveled for a few days, plenty of laptop bag banging around, and no new issues with that fragile Dell battery connector.Worth it!

I received this battery in September but just installed it. I have put it through 3 charging/discharging cycles and it barely lasts 45 minutes on the battery saver settings. I paid $42 for this hunk of crap and am outside the return window. Will never buy from this seller again unless they let me return it.

One year later, with around 5 discharge/recharge cycles per week, holding 45000mAh/55000mAh design.This is not an OEM battery. However, that being said, it has held up for a year. I bought this battery in last February and it is still going.Don't expect the same quality as an OEM battery. It is not the same performance. However, it is about half the price of an OEM battery.

So I had already ordered myself a new laptop and was planning on giving my old one to my 15 yo daughter when the new one arrived. A week before it's supposed to arrive I notice my old laptop is bulging at the front. When I take the back casing off I see it's the battery is expanded out and is about ready to explode. I order this replacement batter which arrive within 2 days (still before my new laptop arrived). This has breathed new life into the machine and my daughter is super excited.On the old battery it wasn't able to stay on without be plugged in for more than about 30-40 minutes. Now I can work more than an hour off the charger. And when it warns that the battery is at 15% it doesn't shut off 10 seconds later.Installing was very easy and quick - took more time to get the old battery out then to put the new one in.Less then $50 and 20 minutes to get a working laptop back to functionality and no longer an explosion danger.

I need a replacement for my E7470 and the battery fit and works like a charm. I will definitely recommend and will definitely do business with them again. Extremely satisfied!!!!

Great value for the price. ZTHYbatteries alway fit and work.

We replaced a bulging battery on a Dell laptop with this one. The laptop has been happy and runs fine away from the mains for periods of time you'd expect from this capacity.

The laptop tested with fully charge battery last about an hour and half, wish it lasted as advertised.

I predict after a month or 2 of use, this battery will be drained and be equivalent to my original.Not worth it, get an OEM battery from Dell instead.Don't get excited by the first month of use.You can keep track of your battery's health by going to Windows Powershell -> powercfg /batteryreport

Battery arrived and was easily installed. Been using it a few weeks now and no issues at all.

works good, lasts longer than the original
