Caution GWS Powercell sells old batteries max. Reach 80% of the rated voltage. Delivered goods do not correspond to the figure, instead of batteries large pack without expiration date! In the case of Varta 377 were measured between 1.1V to 1.3V with calibrated multimeter instead 1.55V Voltage, de facto so empty, clock acknowledged after one day the service. Seller shows unapologetic and claimed he had measured it full rated voltage. Will not take from the offering, the old goods. Seller has taken the shipment back and refund the purchase price. For a star. However, the anger and frustration you can save.
