Garmin 220

[prpwalker]

Ok Icant find anyone else who has this problem so I thought I would try it on here. My astro will work fine with new battries but after two days of running it will start powering off affer 15 min and the battery meter shows full battries any ideas thans

there is a setting on the 220 for whatever battery you are using(alkaline/lithium/ nickle) set it for what u are using. cold weather will also affect the charge.
