Gerrit Van Wijk rated us:
(5/5)
Product:
Sagem 820 battery (1200 mAh 3.7 V, Black)
General:
I'm very pleased with the help and customer support of BatteryUpgrade.com Unfortunately the first item I received did not connect properly. BatteryUpgrade.com has taken its responsibility and was hundred percent willing and cooperative in sending a replacement battery. Very helpful and trustworthy, highly recommended Gerrit van Wijk
About the product:
Hundred percent okay and... this battery has more power (more mAh) than my former battery.
