MagnetoSpeed Battery

[RackOpsTactical]

How do you guys deal with battery management on a MagnetoSpeed. Meaning when do you change to a fresh battery? I've been changing mine out when they get below 8 volts but i'm not sure what is common practice or recommended.

Are you using a 9 volt or are you using the small round lithiums? I only use the lithiums in my MagnetoSpeed and I've only had to replace them recently after using the first set for a few years. Personally, I keep a small set of lithium batteries in my range bag for whatever electronics I'll be using (range finder, Kestrel, ear pro, MagnetoSpeed, etc) so if I'm at the range and I see I'm running out of juice, I can just throw in a fresh set of batteries.

From the manual: "The system will operate normally as long as the battery voltage is over about 3.4V."

Wasnt aware you could use anything other than a 9 volt... what batteries exactly do you use?

You can use 9V or CR123 batteries on the V3.

Just looked at the website that's for the V3 I have the sporter. I'm guessing it's a similar voltage for the sporter.

I use the lithium CR123 batteries. Pay a little extra and go with the lithium for the critical electronics. Regular alkaline batteries can leak and damage the device.

Mine displayed a read out that stated the battery was low and to have another ready. Shortly thereafter read battery critical and would not function until it was replaced.

I run the cr123’s in mine as well and toss a couple extra in the case with it. I have the V3

Ive been running a sporter since summer and it seems to continually show 7.4 or so volts.

Ive wondered same and my seems to be going strong with a few hours of cumulative run time.

I ran my V3 for over 2 years on the original battery before I finally had to replace it.

Ok all I got the offical info from MagnetoSpeed customer service. This is for the Sporter model only!


Hello. Thank you for your past business and support. We recommend that you change your battery if the voltage drops below 6.8-7volts. It's not so much about getting inaccurate readings from the sensors, but more about keeping the display powered to interpret the signals. Also, due to it being winter, try to keep your display warm. This will extend the 9v battery life. If you have any questions, please let me know.

I have the sporter and not sure if it will make a big difference, but just popped some lithium 9v in the other day. Hopefully they’re worth the cost!

Thanks for reporting back with the official response from them. That's good information to know, since it wasn't in the instructions from what I remember.
