Have you checked the Alternator? Like most batterys in cars, trucks, ect, they tend to get dirty. A slow battery drain is more than likely caused by a high resistance ["mini"] short between your positive and negative [+/-] terminal posts. To check this, attach one lead of a low volt meter to the positive [+] post of the battery, and then draw the other lead across the top of the battery. If the meter shows any voltage at all, that's the problem, as it indicates current flow. Wash the battery with a mixture of baking powder & water, and rinse. Be sure the cell covers or plugs are in tight, or if the baking soda solution gets into the battry cells, it will ruin the acid electrolyte. Dry the area between the posts & check with the meter again. ==Answer 3 == While answers 1 and 2 are not wrong, there could be a similar high resistance fault [or mini short] to ground anywhere in the wiring system WHICH IS "HOT" ALL THE TIME [even when the ignition switch is OFF]. One example of this would be where a wire was pinched between two grounded metal body components, or pulled tightly around a sharpe edge of a sheet metal component, with a resultant pinching, chaffing, or cutting of the wire insulation allowing only minimal minimal contact to the grounded component. That would allow a small flow of current which, when the alternator is not generating electricity, would create a small, but continuous drain on the battery. Also, there could be many other possible which I cannot recall at the moment. j3h

Can a bad alternator drain a good battery?
It doesn't actually drain the battery, but without a working alternator to recharge the battery it will only discharge as the car is operated.
How long will it take 532 milliamps to drain a 12 volt battery?
Cannot say as different batteries with the same voltage have different capacity (rated in Ampere Hours). If you had instead asked "How long will it take 532 milliamps to drain a 350 Ampere Hour battery?" that would be much easier (657.89 hours).
Why do car batteries run down in cold weather?
Chemical reactions slow down in the cold. The electricity produced in a car battery is the result of chemical reactions between the sulfuric acid and the lead plates. Slow down those reactions and the battery is not able to produce its normal current.
Does a discharging battery can cause health problems?
Not a 'discharging' battery. Depends on the type of battery. A lead acid battery gives off Hydrogen when 'charging', which could be hazardous to health, if a spark causes it to explode. A 'discharged' battery can have an impact on it's own health. Best to keep them charged.
What causes current to flow from one terminal of a battery to another?
It is too complicated to explain here. Click the link.
What causes a slow battery drain in 2009 Kia Rio?
Can be a dead cell in the battery or any light on the vehicle that is staying on. Can also be a relay that is stuck.
Why does battery die when car is idle?
Something causes a slow drain on your battery. As it does, your battery slowly discharges. If you know that your car will be not used for several months, you might try disconnecting on of the battery terminals.
What causes a car battery to drain on a mercury sable?
A car battery in any car would drain due to a short in the electrical system.
What are the Common causes of not charging phones?
Waiting for the battery to drain completely to extend battery life.
What causes a slow battery drain in an 1988 Olds Toronado?
It depends what you consider to be a "slow drain" the parasidic load on this vehicle will discharge a FULLY charged battery in 21 days. How new is the battery and what state or charge is it in? Have you checked the Alternator? Like most batterys in cars, trucks, ect, they tend to get dirty. A slow battery drain is more than likely caused by a short between your +/- posts. To check this, attach one lead of a low volt meter the + post of the battery, and then draw the other lead across the top of the battery. If the meter shows any voltage at all, that's the problem. Wash the battery with a mixture of backing powder & water, and rinse. Dry the area between the posts & check with the meter again. I've often seen (online) that there is a problem with the load-leveling system which causes this....Here's a page which discusses this:
What causes a battery to drain in a 1984 Buick regal?
Dead cell in battery, a light is on somewhere on the vehicle, or a relay is stuck.
What causes the battery to drain when running?
Defective alternator or voltage regulator. Also possibly the battery is defective with a dead cell.
What causes battery drain in 01 dodge caravan?
Dead cell in the battery itself or something is on pulling power from the battery. A light somewhere or a stuck relay.

How do you open a slow kitchen drain?
One way to open a slow kitchen drain is by using a plunger on the drain. If the drain is still slow put some baking soda and vinegar in the drain to loosen any debris that remain in the drain.
Why shouldn't you put a car battery on the ground?
You can store a battery on the ground, I belive in the old days when the battery case was made from a different material you couldn't. It is an old wives tale that leaving a battery on the ground causes it to drain.
