Use a voltmeter to locate the positive and negative battery terminals and establish the polarity. If no voltage is present, a solid-state switch may be in the “off” position and needs activating. Connect the voltmeter to the outer terminals, take a 100-Ohm resistor (other values may also work), tie one end to ground and with the other end touch each terminal while observing the voltmeter. Repeat by tying the resistor to a positive voltage potential. If there is no response, then it is possible that the battery is dead or locked by a code. The 100-Ohm resistor is low enough to engage a digital circuit and high enough to protect the battery against a possible electrical short.
After a night of charging, check the charge in the morning. If the battery charger indicates that the battery has taken a full charge, inspect the cells and add more distilled water to any cells in which the battery plates are exposed to the air and then replace the cell caps. However, if the charger does not indicate that the battery has accepted a full charge, you need to take extra measures (see Step 8).

The iPhone provides us with many services. We can work from our phones by sending emails, joining work calls, and more. Outside of work, we text or facetime our friends, order dinner, and check our social media. Over time, your battery may start to show signs of needing an iPhone 6 or iPhone 7 battery replacement. If you are considering taking your iPhone to a professional for battery replacement, you might be wondering if the process will affect your phone’s data.

You have to consider that if time is what totally killed the bad cells in a battery pack, the same time has taken its toll on the rest of the cells as well, even if they still work. So it's ideal for a battery pack to have obvious and clear physical damage. This generally ensures that the rest of the cells are fine and still have plenty of life left in them.
iPhone users in most countries can initiate the battery replacement process online by scheduling an appointment with the Genius Bar at an Apple Store. The reduced price is also available at some third-party retailers and repair shops, as long as they are designated as an official Apple Authorized Service Provider.
However, a less generous view of Apple’s decision to increase the price of replacement batteries is that Apple may be attempting to make buying a new iPhone more appealing. As the price of replacing a battery increases, reports suggest that Apple is considering a significant price cut for its lower-end iPhone models.

Great idea , but do you have to pull the battery apart ? Can you not just boost it from the two charging tabs on the stem of the battery ?
Step 4b: Replace any bad cell groups with the closest possible match to the other cells. It’s important to consider the fact that the cells in the battery that you are replacing are more than likely a non-insignificant percentage into their lifespan. So, use great care when choosing what cells you use to repair the battery. The goal is for each cell group to have the same capacity and internal resistance.
