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

Revainrating 2 out of 5

It was a cheap to buy but does not last long

I hardly use my laptop with power cord detached, so over the last few years, the battery has been only used for a less than 100 cycles I would estimated. But now, the battery can barely support one hour. I think despite the battery is hardly used, it just decayed over the time. So overall, for 30 dollars investment, it is an OK deal. If you use it as a backup, i.e. you not really going to depend it for mobile work.

Pros
  • You can use your laptop for longer periods of time, increasing productivity and efficiency
Cons
  • The battery may not be suitable for travel or mobile use
