Review on Dell Laptop Battery E6420, E5430, E6520 & More - Long-Lasting Power For Inspiron & Vostro Models by Travis Caminiti

Revainrating 5 out of 5

Works perfectly - my new review

This battery works perfectly for my Dell Inspiron 17R 7720 laptop. It fits slightly differently into the laptop but it's not noticeable at all unless you're really looking. Pretty much doubled my battery life after replacing the original heavily-used OEM battery - this one lasts two full hours as long as I'm not running a lot of programs (Netflix and homework!), whereas my old one would never make it that long. I had no trouble at all figuring out how to use this battery - it looks and works just like the original. The battery charges in about the same amount of time as my old one which was a little disappointing, but I guess that is due to technical limitations.

  • It's a cost-effective solution for extending the lifespan of your laptop
  • The battery may not be safe to use in certain environments
