<human>:  My vehicle needs a new battery. What type should I buy and how do I install it?
<bot>: The type of battery you should buy will depend on the make and model of your vehicle. You can check the owners's manual or ask a qualified mechanic to help you choose the right battery. To install the new battery, start by disconnecting the negative cable from the old battery and then remove the old battery from the vehicle. Mount the new battery in place and then reconnect the negative cable. Make sure the cables are securely fixed in place and then install the holster for the positive cable. Finally, test the new battery to ensure it is working properly.
