Battery purchased two months ago will …
17 April 2017 Update. Following my earlier bad review (below) Powerguider sprang to life and sent me a replacement battery. I have therefore upgraded their star rating from 1 star to 3 stars.. Battery purchased two months ago will not hold its charge longer than a few minutes, despite following their new battery instructions to the letter. I have e-mailed Powerguider and filled in the "Live Help" on their website (which is not live at all), and they have not responded. There does not appear to be a telephone number to call for help. I have now asked my credit card provider to help me get a refund.
