Surface mount angled battery

1. An apparatus comprising:

an angled battery comprising a proximal end with a proximal axis and a distal end with a distal axis, the angled battery forming a loop and conforming to an outer surface of a wearable monitoring device wherein a display of the wearable device is accessible through a center of the angled battery and the angled battery is removable from the wearable device without interrupting contact between the wearable device and a wearer;

a connector that secures the angled battery to a receiver on the wearable monitoring device; and

power contacts that contact to power receptors on the wearable monitoring device.

2. The apparatus of claim 1 , wherein the angled battery loop forms a circle.

3. The apparatus of claim 1 , wherein the angled battery loop forms a rectangle.

4. The apparatus of claim 1 , wherein the connector is selected from the group consisting of a magnet, a prong, a hole, and a clip.

5. The apparatus of claim 1 , wherein the power contacts are integrated in the connector.

6. The apparatus of claim 1 , wherein the angled battery is a rechargeable lithium polymer battery.

7. The apparatus of claim 1 , wherein the angled battery is packed in a case.

8. The apparatus of claim 1 , wherein the angled battery is sealed with a coating.

9. The apparatus of claim 1 , wherein the angled battery charges and/or powers the wearable monitoring device.

10. The apparatus of claim 1 , wherein the angled battery further comprises a transparent shield.

11. A system comprising:

a wearable monitoring device comprising a display a receiver, and power receptors;

an angled battery comprising a proximal end with a proximal axis and a distal end with a distal axis, the angled battery forming a loop and conforming to an outer surface of the wearable monitoring device wherein the display of the wearable device is accessible through a center of the angled battery and the angled battery is removable from the wearable device without interrupting contact between the wearable device and a wearer;

a connector that secures the angled battery to the receiver on the wearable monitoring device; and

power contacts that contact to the power receptors on the wearable monitoring device.

12. The system of claim 11 , wherein the angled battery loop forms a circle.

13. The system of claim 11 , wherein the angled battery loop forms a rectangle.

14. The system of claim 11 , wherein the connector is selected from the group consisting of a magnet, a prong, a hole, and a clip and the receiver is selected from the group consisting of a magnet, a hole, a prong, and a bracket.

15. The system of claim 11 , wherein the power contacts are integrated in the connector.
