The battery is an exact replacement for my Garmin GPSMap 478. It arrived quickly and is functioning well. A good value and a lot cheaper than the OEM.

This battery works so well I just picked up a second one for my GPS 496. Most of the rentals don't seem to have a 12 or 24v plug. These are cheap insurance when you need to leave the XM weather plugged in. Otherwise, unplug the XM antenna after the first couple of updates, then plug it in once an hour for an additional update to conserve the battery power.

This battery is visibly different from my stock Garmin battery. Initially I couldn't get it to stay in the unit at all. Eventually I was able to push the latch forward enough to make it catch. Hopefully it won't fall out during use. Next time I'll probably pay for the Garmin replacement.

Fast service. This battery fits my Garmin 276C like the original and works as well as the original. I am very pleased.

Wish I could give this a better review, but mine only lasted nine months after four uses, then died never to be revived. As described in other reviews, it did not lock when I first installed it, but I was able to bend the tab and finally get it to lock.

I am about to buy a different brand to replace this one.

The price for this battery is good.
The plastic molded case for the battery is poor.
without finding something to wedge the battery in place the battery will disconnect from the contacts.
This can be aggravating.
This battery replacement is adequate, but not ideal.

Bought this to save a few dollars and really wasted a few dollars instead. While it does fit my gps with no issues it will not charge to more than a quarter way and that took two days while using my car charger. I guess now I am forced to buy the Garmin battery. I wouldn't recommend this battery to anyone.

I purchased the battery despite some bad reviews. I should have known better. The battery does not fit my garmin gpsmap 478 very well. It keeps popping out. However, that is not the only problem. The battery would not charge completely. It would only charge to about a third of its potential.

The origianl battery died as soon as the warranty expired, but this replacement one has been working better then the origianl so far. Great buy. If you realy depend on your GPS then just buy a spare now.

I ordered this battery to use in my Garmin GPSMAP 478. It is so poorly made that it will not stay securely positioned within the battery compartment of the Garmin unit unless you use strong tape (like duct tape or gaffer's tape) to hold it in place. Still worse, when new it would only hold a charge for about two hours. And worst of all, it stopped working entirely after only eight weeks. My advice, pay more for a genuine Garmin battery and be assured that it will fit and function as intended. Why does Amazon continue to offer junk like this for sale?
