I ordered these batteries 3 years ago. This battery may not last as long as the original, but it's worth it. The battery fits perfectly, is inexpensive and reliable in operation. Delivery was very quick and well packaged. Thank you and I'll be happy to order again.

Product usually purchased on Amazon, here it costs less and is shipped sooner (it is the same supplier from which I purchased). The only 'bore' is the lack of tracking for the shipment, but if you are not in a hurry, they arrive home in 3-5 working days max. Advise!

This review was translated automatically. Source language wasHabe diese Akkus schon mal vor 3 Jahren bestellt.
Dieser Akku mag vielleicht nicht so lange halten wie das Original, aber unter dem Strich rechnet es sich. Akku ist passgenau, preisgünstig und im Betrieb zuverlässig.
Lieferung sehr schnell und gut verpackt. Danke und gerne wieder. -

This review was translated automatically. Source language wasProdotto solitamente acquistato su Amazon, qui costa meno e viene spedito prima (è lo stesso fornitore da cui acquistavo). Unica ‘noia’ è la mancanza di un tracking per la spedizione, ma se non si ha fretta in 3-5 giorni lavorativi max arrivano a casa. Consiglio! -
