When it comes to choosing a battery for your hearing aid, two power cells that often come into comparison are the CR1818 and CR1616. Both are popular choices, but they have distinct features that set them apart. Let's dive into a comprehensive comparison of CR1818 vs CR1616, helping you make an informed decision for your hearing health.
First, let's familiarize ourselves with these two battery types. The CR1818 is a lithium coin cell, measuring 18mm in diameter and 1.8mm in height. Meanwhile, the CR1616 is slightly smaller, with a diameter of 16mm and a height of 1.6mm. Now, let's explore their unique characteristics under two main topics.
Battery Lifespan and Capacity
The lifespan and capacity of a battery are crucial factors to consider when choosing a hearing aid battery. Here's how the CR1818 and CR1616 stack up against each other.
Capacity
In terms of capacity, the CR1818 offers more. This is due to its larger size and the fact that it's a 200mAh battery, compared to the CR1616's 160mAh. The extra capacity often means longer battery life for hearing aids that use CR1818 batteries.
However, it's essential to note that higher capacity doesn't always translate to longer battery life. Length of use also depends on the power consumption of your hearing aid. Recreationally, it might be beneficial to have a higher capacity battery like the CR1818. But in professional settings, the power consumption might be lower, making a CR1616 sufficient and even more economical.
Lifespan
The average lifespan of a CR1818 battery is about 240 hours, while the CR1616 typically lasts around 175 hours. These are approximate figures, and actual lifespan can vary based on usage and hearing aid power consumption.
Again, while the CR1818 offers a longer lifespan on paper, the practical difference might not be significant for power-efficient hearing aids. Those with high-power devices might notice a more marked difference and find the CR1818's longer lifespan beneficial.
Compatibility and Size
Besides lifespan and capacity, the compatibility and size of these batteries are also important factors to consider.
Compatibility
CR1818 and CR1616 batteries are both widely used, so you'll find them compatible with many hearing aid models. However, some high-end devices might specify their battery requirements, so it's always a good idea to check your hearing aid's user manual or consult your hearing care professional.
A side note: while both batteries are easy to find, the CR1818 might have better availability due to its wider use in other devices like calculators and wristwatches.
Size
As mentioned earlier, CR1818 batteries are larger than CR1616 batteries. This size difference might influence your preference based on comfort or discreteness. CR1616 batteries are often preferred for their smaller size and lighter weight, making them less noticeable in your ear.
However, the CR1818's larger size can also be an advantage. Its slightly increased dimension provides a more accessible target for those with dexterity challenges, making it easier to handle and change the battery.
In conclusion, the choice between CR1818 and CR1616 batteries will ultimately depend on your specific needs. If battery life, even if only slightly longer, is a priority, the CR1818 might be your best bet. On the other hand, if you prefer a smaller, more discreet battery or want to save a bit on cost, the CR1616 could be your ideal choice. Always consider your hearing aid's power consumption and your personal preferences when making your decision.
