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.
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.
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:
Common causes of a slow toilet drain include clogs from toilet paper, hair, or foreign objects, as well as mineral buildup in the pipes. To fix a slow toilet drain, you can try using a plunger or a drain snake to remove the blockage. If that doesn't work, you may need to use a chemical drain cleaner or call a plumber for professional help.
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.
The battery problem statement typically refers to an issue with a battery, such as reduced capacity, slow charging, or unexpected drain. It can also involve identifying the root cause of the problem and potential solutions to improve battery performance.
Common causes of a slow drain sink include buildup of hair, soap scum, and food particles. To fix it effectively, you can try using a plunger, a drain snake, or a mixture of baking soda and vinegar to break up the clog. If these methods don't work, you may need to call a professional plumber to address the issue.
Batteries drain faster in the cold because the chemical reactions that generate electricity inside the battery slow down in low temperatures. This reduces the battery's ability to deliver power efficiently, causing it to lose charge more quickly.
I'd get your battery trested - It's a FREE service at most Battery outlets.
I don't think the computer not getting electricity will hurt it.
Not all drain guys are qualified such as many franchise companies only give the non skilled 6 weeks of so called training.=Also it depends on the PSI /GPM and what other causes are restricting the flow=
Weak battery or alternator output.
how come when we turn on ac the belts slow down. It takes horse power to operate the ac compressor and the vehicles ECM (engine control module) will compensate for that. If the vehicles charging system and ac system is in good working order it will not drain the battery or effect the idle.
