These batteries are remarkable and very difficult to find. Traders make you believe they do not exist in 1000mAH, the maximum is no more 750mAh. Also found their price is about 5 per unit. I bought them for a fixed wireless phone and it works even better Quà purchase, sale because the devices are provided, with low ranges of batteries. Before this I had to buy a cell phone every one and a half years, the CAD life of original batteries. Then impossible to find a battery that recharges in less than an hour of service communication.les invariably respond that this is the normal life of the new generation electronic devices. Better to try quality food before throwing a device whatsoever.
