When you order the battery, you will be charged a flat-rate deposit, which we will reimburse you after returning the old part and checking whether it can be exchanged. Please return the old part to us within 14 days using the completed return form. The deposit is EUR 80.00. Why a deposit? In the meantime we no longer have access to NEW GOODS, so that in order to continue offering batteries for these devices we are forced to take back defective Telit.SAT550 batteries for repairs. In the foreseeable future, there will only be real replacement batteries.
