Why Won’t My Traxxas Nimh Battery Charge?

If you have a Traxxas Nimh battery, but it won’t charge, keep reading for the reasons why, what you can do about it, the typical life expectancy of these batteries, and learn if they go bad with age…

Why Won’t My Traxxas NiMH Battery Charge?

If your Traxxas NiMH battery isn’t charging, the reasons could range from simple user error to a damaged battery or charger.  Here are the most common reasons:

01. Battery Age and Usage

The first thing to consider is the age and usage history of the battery. NiMH batteries have a typical lifespan of about 500 to 1000 charge cycles. If your battery has been frequently used and charged over a long period, it might be nearing the end of its lifespan.

Over time, a phenomenon known as the “memory effect” can occur, where the battery ‘forgets’ its full charge capacity and is only able to charge to a lower level. In such cases, the only solution might be to replace the battery.

02. Incorrect Charging Procedure

NiMH batteries require specific charging procedures to maintain their health and longevity. If not followed, it could result in the battery not charging properly. Make sure you are charging the battery at the correct voltage and not overcharging it.

Always follow the manufacturer’s guidelines regarding the charging procedure. Also, allow the battery to cool down before recharging, as charging a hot battery can lead to damage.

03. Faulty Charger

The problem may not always be with the battery. If your Traxxas NiMH battery isn’t charging, the charger itself could be faulty. Inspect the charger for any visible damage, such as frayed wires or damaged connectors.

If you have access to another charger, try using it to determine if the issue lies with the original charger.

04. Battery Damage

Physical damage to the battery can prevent it from charging. This may include leakage, swelling, or signs of overheating like discoloration. In such scenarios, the safest option is to replace the battery as it can be hazardous to continue using.

05. Environmental Factors

Environmental conditions can affect battery performance and its ability to charge. NiMH batteries should be charged in a cool and dry environment.

Charging in overly hot or cold conditions can impact the battery’s effectiveness. Ensure that you are charging your battery under appropriate conditions.

What is the Life Expectancy of a NiMH (Nickel-Metal Hydride) Battery?

Nickel-Metal Hydride (NiMH) batteries have gained prominence in many sectors due to their reliability, reusability, and capacity to power a broad array of electronic devices.

However, just like any other battery, NiMH batteries have a finite life expectancy, which users should know to plan their usage and replacement schedules effectively.

This article delves into the life expectancy of NiMH batteries, exploring factors that influence it, and provides tips on prolonging the batteries’ service life.

Understanding the Life Expectancy of NiMH Batteries

The life expectancy of NiMH batteries depends on several factors, including their usage, charging cycles, environment, storage conditions, and manufacturing quality.

Typically, NiMH batteries can endure between 500 to 1000 charging cycles before their performance starts to degrade significantly.

Given this, under normal conditions where the battery is fully discharged and then recharged once daily, a NiMH battery can be expected to last approximately 1.5 to 3 years.

However, in most practical scenarios, the battery is not entirely drained before being recharged, which can extend its lifespan beyond this estimate.

The stated figures are average estimates, and the actual life expectancy can vary depending on the battery’s manufacturing quality and how it is maintained by the user.

High-quality batteries from reputable manufacturers often exceed the average life expectancy, while batteries from lesser-known manufacturers might not reach these averages.

Factors that Impact NiMH Battery Life Expectancy

  1. Usage and Charging Cycles: The more frequently a battery is charged and discharged, the faster it wears out. Overcharging can also degrade NiMH batteries, causing them to heat up and potentially damaging their structure and reducing their lifespan.
  2. Environmental Conditions: NiMH batteries are sensitive to extreme temperatures. Using or storing them in very hot or very cold conditions can degrade their performance and shorten their lifespan. The optimal operating temperature for NiMH batteries is around room temperature (20°C to 25°C or 68°F to 77°F).
  3. Storage Conditions: If NiMH batteries are not in use, their charge slowly dissipates over time, a phenomenon known as self-discharge. While this process is natural, it can be accelerated by poor storage conditions such as high temperature and humidity.

Prolonging the Life of NiMH Batteries

  1. Proper Charging: Avoid overcharging NiMH batteries, as it can cause them to heat up and degrade faster. Use a smart charger that automatically stops charging once the battery is full to prevent overcharging.
  2. Appropriate Usage: Avoid completely discharging your NiMH batteries. While they do not have a significant memory effect, frequent full discharges can still shorten their lifespan.
  3. Good Storage Practices: If you plan on not using your NiMH batteries for a while, store them in a cool, dry place. Also, it’s better to store them with a 40-50% charge, recharging them every few months to prevent them from completely discharging.

Do Rechargeable NiMH Batteries Go Bad If Not Used?

Nickel-Metal Hydride (NiMH) batteries are a common type of rechargeable battery used in various electronic devices. As with any technology, many users wonder about their longevity, particularly when not used for extended periods.

This article will explore the impact of inactivity on NiMH batteries and provide some insights into how to prolong their life.

Overview of NiMH Batteries

NiMH batteries represent a substantial improvement over the older Nickel-Cadmium (NiCd) batteries. They have a higher energy density, meaning they can store more power than NiCd batteries of the same size.

Additionally, they don’t suffer from the notorious “memory effect” as much as their NiCd counterparts, where batteries would lose their maximum energy capacity if repeatedly recharged before being fully discharged.

Despite this advantage, NiMH batteries are not immune to performance degradation over time.

Can NiMH Batteries Go Bad if Not Used?

The short answer is, yes. All batteries, including NiMH types, will degrade over time, whether they are in use or not. The rate of degradation, however, can be influenced by various factors, including temperature, storage conditions, and charging cycles.

One of the main culprits for NiMH battery degradation is self-discharge. Self-discharge refers to the natural process whereby a battery loses charge while not in use.

NiMH batteries are known to have relatively high self-discharge rates, losing anywhere from 10% to 20% of their charge in the first 24 hours after charging, followed by approximately 10% every month thereafter.

Temperature also plays a significant role in battery lifespan. If stored in a hot environment, NiMH batteries may degrade faster. Ideally, these batteries should be stored in a cool, dry place to minimize degradation.

While not being used, NiMH batteries do not undergo charging and discharging cycles. However, the absence of these cycles does not necessarily equate to an extension of the battery’s overall life. Regular use can contribute to maintaining a battery’s capacity.
