Our Technician will come to your place, un-install the battery, take it to our store and keep for charging using our state of the art charging machines. Once battery is charged with the required voltage, it will be kept for observation for few hours to check the battery can hold the voltage and not discharges fast. If the battery is holding the voltage, the technician will bring back the battery and fits it to your vehicle. This complete process will take minimum 1 day. If the battery is not able to charge or hold the required voltage, our technician will call and inform you to replace battery. You can order a new battery and we will bring and fix it with no extra installation fee. You need to pay only for the new battery.
