If you have a vehicle that you plan on storing for a whole season, it's a good idea to remove the battery entirely. store the battery in a battery box and place it in a dry, well ventilated area with a steady temperature of between 40℉ and 60℉. this will help extend the life of the battery. even though disconnecting the battery will slow. Touch a lead to the negative battery cable terminal. touch the other lead to the negative battery post, completing the circuit within the multimeter, which will display the amp draw. power draw should be under 50 milliamps. this will display as 0.05 amps. if it's higher, that is your parasitic power draw.
Attempt to start the dead car: try to start the engine of the car with the dead battery. if it works, disconnect the jumper cables. if not, wait a few seconds and try again to start the dead car. Hold the voltmeter to the terminals of the battery. try and start the vehicle and watch your voltmeter readings. a healthy 12 volt battery should maintain a reading above 9.5 volts while under a load. if it holds but then starts to drop, there is an issue. most likely, there’s a dead cell. So, if the clamp seems stuck at first, try to move the clamp's sidearms up and down to remove them from the battery tray at the bottom. once they're free, the entire clamp will quickly come off. 5. remove the dead battery. have a level, dry place to set down the old battery before lifting it from the car. Connect one end of the negative jumper cable to the negative terminal on the charged battery and the other end of the cable to a grounded metal component on the car with the dead battery, like the frame or chassis. turn on the car with the charged battery. leave the cars connected for at least five minutes.

Clean the battery cells. make a baking soda and water solution in a 2:1 or 1:1 ratio. using a funnel, pour the mixture into each of the battery cells. make sure that each cell is full, then replace the plastic caps of the battery until they are secure. shake the battery carefully for two to three minutes. Using hot ash. if the battery is dead because of freezing conditions, it might be a good idea to revive the battery. to do so, gather some hot ash and disconnect the battery from the car. then remove the filler cap from the battery and place it on the ash. after that, wait for a while until the battery is warm enough.
