How do I know when my rechargeable battery is at the end of its life?

You just charged your device, but it’s already running low. You used to get 6 hours out of a charge and now you’re only getting 90 minutes. These situations are common in our daily lives. However, before you discard those batteries, let’s learn how to check their condition.

There are two common indicators that your rechargeable batteries need replacing:

  1. The battery has been used extensively over a few years, and it’s lasting a fraction of the time that it used to.
  2. It’s taking significantly longer times to fully charge.

Rechargeable batteries are most commonly worn out by three things: number of charging cycles, heat, and age.

You should expect 500-1000 recharge cycles out of any given battery before you’ll see noticeable degradation. Once you’re hit this many cycles, you can reasonably assume that the battery is at the end of its life. And, rechargeable batteries work best when kept around 68-77 degrees Fahrenheit (20-25 degrees Celsius). Keep them out of direct sunlight when charging.

However, there are some indicators that might suggest the battery and the device might not have great contact.

  • The charge never completes or takes a much larger amount of time (2 to 3 times longer than the normal charging time).
  • When the battery drains quickly, but it’s only been used (recharged) a few times.

In these cases, the best course of action is to clean the battery terminals and the charger connectors. A microfiber cleaning cloth will work, and isoproyl rubbing alcohol is typically safe for cleaning electronics without leaving behind moisture and other residue.

It is worth noting, though, your phone’s battery is also affected by how you use your phone. Things like the apps you install, the stuff you collect, the number of ads you’re exposed to on websites, the number of notifications you received, whether you are using WiFi or data all effect how much strain is put on the phone’s battery. The more you ask your phone to do, naturally will cause it to deplete faster.

How to treat corroded battery terminals

Corroded battery terminals can prevent your vehicle from starting. You could have so much corrosion around your battery connections that the resistance is stopping the current from getting through to start your vehicle.

Battery corrosion is caused by hydrogen gas being released through the battery vents from the acid inside the battery. This mixture builds up over time and is the white, green, or blue tinted corrosion we see on battery terminals or cables.

Most often the corrosion occurs on the negative battery terminal, which is a sign of undercharging the vehicle’s battery. This typically happens when the alternator does not have enough time to replenish the lost battery capacity. Battery corrosion on the positive terminal is normally from overcharging. If this is what you are seeing in your vehicle, it may be best to have your alternator checked for proper output.

Once corrosion occurs, if the buildup is not too severe, the terminals can be cleaned by using a battery cleaner with sandpaper or a wire brush to loosen up the corrosion and scrub it away. Before doing this, you should turn your vehicle off and disconnect the battery cables from the vehicle. For safety the negative cable should be disconnected first, and hooked up last. A solution of warm water and baking soda will neutralize any acid on top of the battery or in the vehicle tray.

Sometimes, a corroded battery cannot be sufficiently cleaned, and it is time for a replacement. When inspecting your battery, be sure to check the condition of the case itself. If it is leaking or swollen, it is time to replace the battery instead of cleaning the corroded terminals and cables.

The best way to fight corrosion is to prevent it from ever starting. You can use a spray battery protector which is meant to prevent corrosion build-up on battery terminals and cables. Always start with a cleaned-up connection and read the manufacturer’s directions before use.
