Purchased replacement battery pack for my ageing lap top. After going through 3 charge/discharge cycles the battery is working perfectly at a much better price than an original. The one negative comment is that no guarantee details are shown on the purchase invoice.
Battery looks good. Instructions included to advise how to prime battery, 4 charging / de-charging cycles. Battery was better than my original Acer one, it was giving over 4 hours video playback on full charge.
Another excellent product, simple to insert.
