CELLONIC, Battery for Navigation, compatible with Garmin Alpha 100, Montana 600, Monterra™ (3.7V, 2200mAh)

Bought this battery as a replacement for my Garmin Alpha 200i dog tracking unit,works absolutely perfect & I also have the Garmin Alpha 100 dog tracking unit & it works great in that too so it's a win,win situation for me. I'm very happy with it, battery life obviously exceeds the older battery with it being new,well worth the money. Thank You

Purchased to use with original Garmin Virb action camera. Correct dimensions, charges fine, works fine. Slightly more mAh than original battery.

Got as a backup battery for Garmin Alpha 200i GPS/Dog Tracker. Only drawback I can see is that battery charge state does not show on screen of Alpha whilst charging, whereas the original battery does. Charge state shows normal icon on Alpha when in use, so this is hardly a deal breaker. So, if you’re OCD, avoid. If you want the peace of mind of a functional back up battery when out with the dog, get one!

Failed within months.

Disappointing. Probably ok as a backup, but I wanted it as a replacement battery for my Montana ...about 6 hrs runtime. Not much good if your on the go all day.

I bought 5his battery to replace a old worn out one. This was no better. Quite dissappointed!
