Buying Guide for Golf Rangefinder Battery
Buying the best hunting rangefinder requires a long lasting, temperature tolerant & durable battery which is easier said than done. To get your hands on the right product, you must know the important considerations. This buying guide will help you understand the key factors that you must understand before purchasing a rangefinder battery:
CR2 vs. CR123A
Simply put, CR123A is an advanced version of CR2 batteries. In physical appearance, 123A batteries are slightly longer than the CR2s. Unfortunately, CR2 can’t be a replacement choice for CR123A since these cannot fit in the majority of the applications where 123A is required.
Because of the larger size, CR123A is capable of delivering as much as 50% more output than a CR2 battery. This means, if you were successful in using a CR2 cell in a device that requires a CR123A cell, the gear won’t perform up to its maximum potential.
Speaking of the similarities between these batteries, both are crafted out using lithium manganese dioxide. In addition to this, both are 3-Volt batteries.
Types of Rangefinder Batteries
There are two common types in which rangefinder batteries are available. One can choose it based on their personal preference. In my experience, both types did a decent job however, we liked the performance of rechargeable batteries more.
- Rechargeable Batteries
As referred by the name, you can recharge these batteries when they are out of juice. Rechargeable cells come pre installed in the rangefinder and cannot be detached. These are best recommended for rangefinders. The main reasons include its cost-effectiveness and longer lifespan in comparison to others. These batteries would last somewhere between 3 to 5 years.
- Replacement Batteries
These are not fixed to the rangefinder hence are disposable cells that need to be replaced when they run out of power. Replacement batteries have a usual lifespan of 6 to 8 months.
- Self Discharge Batteries
While purchasing cells for your rangefinder, ensure that it has a low self discharge. This is a process when the stored charge of batteries is reduced due to the chemical reactions occurring inside, resulting in diminishing the overall shelf life of a cell.
The lesser the self-discharge rate, the greater will be the shelf life. It is suggested to look for batteries that don’t degrade more than 5% within a year.
Frequently Asked Questions (FAQ’s)
A CR2 battery life will differ based on manufacturer and usage. On average, most CR2 batteries work fine for 2 to 5 months for high draining usage like cameras, ranging tools and lights. However, some extra ordinary units such as Duracell and Energizer can last more than 5 months.
Some CR2 batteries are rechargeable while some aren’t. You can determine which one is rechargeable simply by its name. For example, a CR2 cell which is also known as a ‘secondary battery’ is capable of recharging. However, one called a ‘primary battery’ is non-rechargeable.
Typically the majority of rangefinders can fit 27mm x 15.6mm of CR2 batteries. Whereas, for CR123A batteries, the ideal size is 34.5mm x 17mm.
The Bushnell rangefinder battery type vary between CR2 and CR123A. You can choose the right cell type based on the requirements of the Bushnell rangefinder.
Rangefinders have made the lives of golfers and hunters hassle-free but, it could still become a headache if not combined with the best rangefinder battery. In my pursuit of testing new batteries, I was lucky to find a couple of excellent cells. All the aforementioned choices work impeccably well for various rangefinders. However, the one our team loved the most is Duracell – CR2 battery.
If your rangefinder’s battery is out of power, make sure to look for one that promises a longer lifespan. Don’t overlook the important considerations and choose wisely. Wishing you all the luck!
