just bay new or used via EBAY,because some charger unrepairable.one time my opened hp original charger circuid was filled in some solid material.
i found as a temporary battery i can use a 12 volt and a 6 volt battery wired in series to make 18 volts and then solder it onto my laptops old broken charger cable works great i just had the idea the other day and to charge them i just use a lead acid battery charger i can charge them while it is plugged into the laptop the laptop doesnt care still keeps running and will work for most laptops as 18 volts is pretty standard.

The price increase is not limited to iPhone, with the iPad battery replacements increasing by $20 for all models except the latest iPad Pro and the entry-level iPad. Mac users do not miss out on the price increases, with Apple set to charge $30 more for all MacBook Air models and $50 more for MacBook and MacBook Pro models.
The problem is that the iPhone Pro models are more appealing to consumers, with only a $200 price difference between the existing iPhone 14 Plus and iPhone 14 Pro Max. Both phones have the same screen size, but the Pro Max offers the latest A16 chip, a ProMotion display, a telephoto camera and a stainless-steel design.
Measure the voltage of a repaired pack and check it again after 24 hours and a few days. If a cell drops lower than another in the pack, then there is fear of elevated self-discharge(See BU-802b: Elevated Self-discharge) Simple Guidelines when Repairing Battery Packs Only connect cells that are matched. Do not mix cells of different chemistry, age or capacity.Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit.Include a temperature sensor that disrupts the current should the pack get hot.Apply a slow charge to a repaired pack to bring all cells to parity.Pay attention when using an unknown cell brand. Elevated temperature hints to an anomaly.Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time.Check a repaired pack for self-discharge. Intrinsic defects often reveal themselves in an elevated self-discharge. Previous Article Next Article
Absolutely. Battery is a consumable part and it diminishes over usage. With new battery replacement, your old iPhone lifecycle is extended by at least a year or more.
1) They get too low, they're useless now. They will shut off before they get too low, but;
Give the battery another overnight charge as described in Step 6. The Epsom salts should remove deposits on the battery plates which previously prevented the battery from taking a full charge. Check the battery in the morning. If the battery still won't take a full charge, it likely cannot be saved. If the battery has taken a charge, replace the cell caps and use your cart normally. Put a trickle charger on the batteries every night to keep the batteries in peak condition. Use only distilled water inside your battery. Never use tap water as the chemicals in tap water will destroy your battery. Do not get battery acid or the white/yellow corrosion on the batteries on your skin or clothing as this acid can burn and destroy material in a very short time. Always wear gloves and eye protection when working on lead acid batteries.Always be sure to properly maintain your golf cart.
Yes. A lithium-ion battery pack that has one or more bad cells can be extremely dangerous, especially if it's put under a heavy load. Battery packs are made from many lithium-ion cells.

We put together a guide on how to get more life out of batteries, and easy-to-use tips to keep your battery healthy.
Granted your battery is in top performance condition, the battery should charge in roughly two hours or less. iPhones that take more than two hours (or just don’t seem to want to charge no matter how long they’re plugged in) personify this classic symptom of a dying battery. Thus, a phone that takes too long to charge is another clear indication that you’re in dire need of an iPhone battery replacement.
Thanks for the information. I tried it on a 2ah, using a 12V car battery trickle charger. I got the battery pack up to 11.5 volts; but it still won't charge. Is there a way to see if I have a dead cell (other that cutting the cell connectors) and replace a dead cell? Or, is there something else wrong with my battery? Thanks.

While many damaged batteries can be repaired, sometimes this is simply not possible. For example, it’s usually not possible to repair a battery that has a severely damaged exterior or terminals. However, it is usually possible to repair a battery that simply does not have enough acid in it anymore. Will charging your battery for an exceptionally long time allow it to hold a charge again?
I've seen an atrouceous comment here advising to discharge the battery completely
