Bought batteries from this seller as thought stocked in UK . but considering time taken to receive same must surely have come from Far East. The batteries eventually arrived and are working well as expected. The seller was very attentive when contacted via Amazon and I am happy with purchase at cost paid .Possibly would buy again in future.
