The best time to think about your car battery is before it goes dead and leaves you stranded. So, we’re here to test your battery regularly and replace it when its voltage is low… but not too low.

Hi, I have a laptop battery which is suspect. However, I am not sure whether it is a problem with the cells or a problem with the way the laptop is charging the battery. I have opened up the battery. It is organised into three pairs of cells. Each pair is connected in parallel. I don't want to disconnect the cells from the battery circuit board, so I was wondering if I can connect my 18650 battery charger and charge (in place), each pair of batteries in turn?

If you have distilled water and aspirin (acetylsalicylic acid), you can make a solution to chemically alter the electrolyte mix. To make aspirin and distilled water solution, you need to crush 12 350 mg or 500 mg aspirin tablets and dissolve the powdered aspirin in about 6 oz of warm, distilled water. Then add equal amounts to each cell. You may need to add more water to cover the plates.
After jump-starting your vehicle, determine how dead the battery is before you try to fully recharge it. You can do this with a voltmeter or multimeter.
Most laptop batteries are smart and consist of the “chemical battery” that is managed by the “digital battery.” A common protocol is the System Management Bus, better known as SMBus.
First time customer, brought BMW in for major repair, great customer care and review of work completed, job done in a timely manner and for quoted amount. Will be recommending Peter's to friends and family going forward. Thanks to Peter…
The internal document also stated that customers may be eligible for a refund if they replaced their iPhone battery for a higher price. We've heard these requests are handled exclusively by Apple Support, and only for replacements completed on or after December 14, 2017. Your mileage may vary.
The battery should read at least 12 volts. If your reading shows 10 to 12 volts instead, you may be able to restore the normal function through reconditioning. However, there’s no reason to try it once the battery reaches below 10 volts if you recharged it quite recently. At this point, you are better off getting a replacement.
Household batteries work, work weakly, or don’t work at all. They quit working because they corrode, leak, and lose their power.
Followed this article step by step! Successfully reconditioned the car battery. Just saying thanks for the article.
Lead- and nickel-based batteries are more or less uniform and one can say that lead acid is lead acid and NiMH is NiMH. This cannot be uttered about the lithium-ion family as it has diverged into many unique systems and some with different voltages. While most Li-ion has a nominal cell voltage of 3.60V and charges to 4.20V, some specialty Li-ion charge to 4.10V and newer Energy Cells top at 4.35V/cell and higher. Li-phosphate presents a further exception with a nominal cell voltage of 3.20V and a charge limit of 3.65V/cell. Also unique is Li-titanate with a nominal cell voltage of 2.40V and charge limit of 2.85V(See BU-205: Types of Lithium-ion) These cells are definitely not interchangeable.

When you arrive at an Apple Store, find an employee holding an iPad, who should be able to check you into your Genius Bar appointment. If you chose a service provider instead, ask a staff member for help.
Fast good service, pleasure to deal with. Broken screen was fixed quickly on the same day.
Have a relatively new phone? If your phone or tablet is still under the manufacturer’s warranty, you may think that repairing your phone with fix2U may void your warranty. Good news – this is now no longer the case, following the landmark action from the ACCC, which now gives you the freedom to choose more cost effective phone repair providers such as fix2U, without losing your warranty.
