    works ok.....
  

*by G***  on Reviewed in the United Kingdom on 28 February 2023*

arrived in good time and is what i ordered... so far so good.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Battery capacity is in excess of manufacturer
  

*by M***E on Reviewed in the United Kingdom on 26 January 2022*

This battery was supplied after a previous purchase. The internal fit and voltage/capacity specification are exactly what I required to replace my failed previous battery. The price is also lower than manufacturer spare.

### ⭐ 1.0 out of 5 stars







  
  
    Dangerous a accident waiting to happen. Please check your battery if have brought one.
  

*by T***4 on Reviewed in the United Kingdom on 2 November 2023*

I ordered this battery yesterday and it arrived today.Opened box, took battery out and went to install when noticed out of the corner of my eye that one of the cables coming out of battery was snapped.If I had tried to install and use this battery and charged it then snapped cable would probably have sparked and caused battery to explode and laptop to catch fire.Please please if you have brought this battery please go back and check the cables and make sure none are damaged.This is a very dangerous battery and a accident waiting to happen. Don't want any one to try installing one of these and end up getting hurt.Would not recommend buying this battery, spend more for a decent safe battery.
