A golf rangefinder is a valuable tool on the course, but it’s only useful when it has power. If you find yourself replacing batteries more often than you'd like, here are some practical tips to extend your rangefinder’s battery life:
Many golfers leave their rangefinder on between shots or holes. Make it a habit to power it off manually to prevent unnecessary battery drain.
Batteries lose efficiency in very hot or cold environments. Try to store and use your rangefinder at moderate temperatures whenever possible.
If you’re not playing for weeks or months, take the battery out. Even when powered off, some rangefinders slowly drain the battery in storage.
Cheap or off-brand batteries may not last as long or perform consistently. Always choose reputable brands or those recommended by the manufacturer.
Advanced features like slope measurement and continuous scan mode consume more power. Use them only when necessary to conserve battery.
If your rangefinder has firmware, check the manufacturer’s website for updates. Software bugs can sometimes cause unnecessary battery usage.
