How To Recondition Batteries A Diy Project

Car battery dead cell repair

Most shops will not attempt to revitalize a battery, as a simple replacement is less time consuming, and these shops can sell a new battery to the consumer in the process.

Because of this, if you intend to have your battery reconditioned, your only option typically becomes doing so yourself.

Handling batteries, especially when working around acid, can be quite dangerous. Care must be taken to always wear personal protective equipment.

At the bare minimum, rubber gloves of elbow-length and goggles should be worn when attempting a repair of this nature.

If you feel as if you are uncomfortable with the idea of working around battery acid and other corrosive chemicals, or you do not have the suitable personal protective equipment at your disposal, complete battery replacement will likely be your best option.

If you do decide to tackle DIY battery reconditioning, you will likely be saving yourself a considerable amount of money.

The supplies needed to complete this task are no more than basic hand tools, distilled water, and a manual battery charger.

Assuming that you have basic hand tools and a battery charge available to you, the entire revitalization process will likely cost less than $10.

This is a vast improvement over the costs of new battery replacement, especially if done by an industry professional. Typical costs for new battery installation are as follows:

Low End Cost

$75 + $20 = $95

Average Cost

$110 + $20 = $130

High End Cost:

$150 + $20 = $170

Removing Heatshrink And Tapes

Remove the exterior plastic packaging from the LiPo battery. Make sure you are cutting on the side with the internal protective layer. This thicker flexible layer will help ensure that you do not puncture any of the cells with your knife.

Remove the tape wrapping around the cell terminals, then unsolder the balance wire and XT60.

What Are Some Causes Of A Bad Cell In The Car Battery

how to revive old car battery dead cell

This is something that people are looking to know about so that they can get rid of the facts that cause dead cells in the car battery. There are a lot of reasons why the battery cell goes bad, but the most common ones are mentioned here.

Bad Electrolyte

Whether you are using the bad electrolyte that can be a mixture of raw acid with distilled water, using tap water in the batteries, or the level of electrolyte in your batteries is very low. Any of these can be the cause of the battery cell to go bad.

It is because the batteries are designed in such a way that the plates are electrically connected with the help of an electrolyte and this electrolyte must be free of any types of contaminants.

Additionally, the electrolyte must be made from the best quality materials and its level inside the battery must also be maintained. So, when any of these things is ignored while regularly using the battery, one or more cells inside the battery can go bad.

Intensive Vibration or Collision

Apart from the issues related to the electrolyte of the battery, the collisions or vibrations that are unbearable for the battery can also cause a cell to go bad or even dead. It is because the battery cells are made with plates that are not meant to come in contact with one another.

However, these collisions or vibrations may cause the battery plates to come in contact and this causes short battery plates. When this happens, the battery cell is not good anymore.

What Causes A Car Battery To Keep Dying

Some of the most common reasons for a car battery to die repeatedly include loose or corroded battery connections, persistent electrical drains, charging problems, constantly demanding more power than the alternator can provide, and even extreme weather. Some of these problems are enough to kill a battery on their own, while others are usually coupled with a battery that is already weak or on its last legs.

  • Headlights or dome lights left on.
  • Headlights, or even a very dim dome light, will drain a battery dead overnight.
  • Make sure to check for any interior lights when it’s dark outside.
  • Some headlights are designed to remain on for a while, but a malfunctioning system may leave them on permanently.
  • Battery in weak or poor condition.
  • A poorly maintained or weak battery may not hold a charge very well.
  • Even small drains, like the memory function in your car radio, may kill a very weak battery.
  • Corroded or loose battery connections.
  • Corroded battery connections can prevent the charging system from topping off your battery when you are driving.
  • Loose battery connections can also cause problems.
  • Other parasitic drains in the electrical system.
  • Parasitic drains can be difficult to find, but they are fully capable of killing batteries dead.
  • Common drains include glove box and trunk lights that come on, or remain on, when they shouldn’t.
  • Extremely hot or cold temperatures.
  • Extremely hot or cold weather can also magnify other underlying issues.
  • Charging system problems.
  • Use Epsom Salt Solution

    If the problem is caused by a low electrolyte level, using Epsom salt to make an electrolyte solution will help revive your car battery. Check out this article on how to check your batterys electrolyte level. Epsom salt is a stronger acid, which contains a variety of hydrates, and it might help tip the chemical balance and deliver enough charge to start the engine.
