When an unattended car leaves your battery dead.
Ever wonder why your car is unable to start after left unused for merely a week or two? Car batteries like any of your regular phone battery loses it’s charge over time even when you don’t use it. Electricity is produced as electrons flow from the lead oxide anode to the metallic lead cathode, through a solution of sulfuric acid (Science, yo!). That reaction is ongoing, but at a slower rate, when the battery isn’t being used. That explains why batteries loses their charges as they sit. If the battery is connected to your car, it drains even faster. Why so? Your car has an alarm system, on-board computers and memories for seat positions and radio and climate control settings. You might ask how long will it take to drain. That depends on several factors; age of the battery, the climate and how often you drive. Here are three ways to keep your battery charged.
1. Start The Car Regularly
Arrange for someone to start the car every week and take it for a spin for about 30 minutes. Driving a good distance (about 20-30KM) not only gives the battery a proper charge but it also keeps the engine and other components properly lubricated. Pros: Your car will have a consistent upkeep and your friends or family will get to borrow your ride. Everyone’s happy! Cons: If it’s a luxury car, then you would have to be open-minded that your friend will take good care of her.
2. Detach the negative cable
Don’t have friends or family members who are available to start the car? Here’s the low-tech solution. Disconnecting the negative cable will stop the rapid drainage by the car’s electrical system. You’ll likely to lose the stereo presets, time and other settings. Hence, this method is not advisable for higher-end cars with plenty of power-hungry gadgets and computers. Pros: You don’t have to spend a single cent. Just make sure that the terminals are clean before attaching the cable back. Cons: If your battery is fairly old, it might discharge quite quickly even with this method.
3. Install a trickle charger
We all would want to keep those settings and ensure that the battery starts the moment we return. Invest in a trickle charge, also known as a smart charger. Unlike the conventional charger, which can eventually overcharge a battery, a trickle charger only delivers as much power as your battery needs. It will turn off current when it’s fully charged. Pros: They can stay in the car all year round. Practically you just plug it in the car and forget about it. Cons: If you are staying in a condominium or other high-rise, you might not have regular access to an power outlet.
