Abstract

A battery charger (100) includes a charging pocket (112) capable of receiving either a first battery (102) in a first orientation or a second battery (104) in a second orientation. The charging pocket (112) includes a first set of contacts (170) and a second set of contacts (152). The contacts (172-175) of the first set of contacts (170) have a first spacing so as to mate with contacts (187) disposed on the first battery (102) when the first battery (102) is inserted into the charging pocket (112). The contacts (154-157) of the second set of contacts (152) have a second spacing so as to mate with contacts (199) disposed on the second battery (104) when the second battery (104) is inserted into the charging pocket (112). By providing two sets of contacts (170, 152) in a single charging pocket (112), the battery charger (100) can charge batteries (102, 104) having dissimilarly positioned contacts.

Claims

1. A battery charger including a first pocket for charging a plurality of batteries, each of the plurality of batteries including a set of battery contacts, the first pocket receiving one of the plurality of batteries at a time and including:

a first set of charging contacts positioned in the first pocket to connect to a first battery of the plurality of batteries when the first battery is inserted into the first pocket, the first set of charging contacts having a first spacing thereamong; and

a second set of charging contacts spaced from the first set of charging contacts and positioned in the first pocket to connect to a second battery of the plurality of batteries when the second battery is inserted into the first pocket, the second set of charging contacts having a second spacing thereamong.

2. A battery charger according to claim 1 wherein the first pocket includes a first well formed about the first set of charging contacts, the first well to accept the first battery in a first orientation.

3. A battery charger according to claim 2 wherein the first pocket includes a second well formed about the second set of charging contacts, the second well to accept the second battery in a second orientation.

4. A battery charger according to claim 3 wherein the first set of charging contacts are carried on a first wall of the first well and the second set of charging contacts are carried on a second wall of the second well.

5. A battery charger according to claim 4 wherein the first wall of the first well and the second wall of the second well are on different sides of the first pocket.

6. A battery charger according to claim 3 wherein the first well includes a ledge circumscribing the second well, the ledge supporting the first battery above the second well.

7. A battery charger according to claim 3 wherein the second well extends downwardly from the first well such that the second battery extends upwardly through the second well and first well when accepted in the second well.

8. A battery charger according to claim 3 wherein the first orientation is orthogonal to the second orientation.

9. A battery charger according to claim 1 wherein the first pocket includes a second well formed about the second set of charging contacts, the second well for accepting the second battery in a second orientation.

10. A battery charger according to claim 9 wherein the second well includes opposing rib members, the opposing rib members engaging slots disposed in the second battery for maintaining the second battery in the second orientation.

11. A battery charger according to claim 1 wherein contacts of the second set of charging contacts are positioned substantially closer together than contacts of the first set of charging contacts.

12. A battery charger according to claim 1 further including a second pocket, the second pocket separate from the first pocket for accepting a battery powered electronic device therein.

13. A battery charger according to claim 12 wherein the second pocket includes a connector for engaging the battery powered electronic device and delivering power thereto.

14. A battery charger including a first pocket for charging a plurality of batteries, each of the plurality of batteries including a set of battery contacts, the first pocket receiving one of the plurality of batteries at a time and including:

a first well for accepting a first battery of the plurality of batteries in a first orientation, the first well including a first set of charging contacts, the first set of charging contacts for contacting a first set of battery contacts of the first battery when the first battery is accepted in the first well in the first orientation and delivering a charging current thereto; and

a second well for accepting a second battery of the plurality of batteries in a second orientation, the second well including a second set of charging contacts, the second set of charging contacts for contacting a second set of battery contacts of the second battery when the second battery is accepted in the first well in the second orientation and delivering the charging current thereto, the second orientation dissimilar from the first orientation.

15. A battery charger according to claim 14 wherein the second orientation is orthogonal to the first orientation.

16. A battery charger according to claim 14 wherein the first set of charging contacts have a first spacing thereamong and the second set of contacts have a second spacing thereamong, the first spacing differing from the second spacing.

17. A battery charger according to claim 14 further comprising a second pocket, the second pocket separate from the first pocket and adapted to receive a battery powered electronic device.

18. A battery charger for charging a plurality of batteries, the battery charger including:

a first pocket adapted to receive one of a first battery of the plurality of batteries and a second battery of the plurality of batteries, the first pocket having a first set of charging contacts for mating with battery contacts of the first battery and a second set of charging contacts for connecting to the second battery when the second battery is inserted into the first pocket, the battery charger supplying charging current to the first set of charging contacts and charging the first battery thereby; and

a second pocket adapted to receive a battery powered electronic device having a third battery of the plurality of batteries attached thereto, the second pocket having a first connector for engaging a second connector of the battery powered electronic device and supplying power thereto, the battery powered electronic device charging the third battery from the supplied power.

19. A battery charger for charging a plurality of batteries, each of the plurality of batteries including a set of battery contacts, the battery charger including:

a first pocket for receiving one of the plurality of batteries at a time having a first well and a second well, the first well adapted to receive a first battery of the plurality of batteries in a first orientation, the first well including a first set of charging contacts, the first set of charging contacts having a first spacing thereamong, the first set of charging contacts for mating with a first set of battery contacts of the first battery when the first battery is received and delivering a charging current to the first battery, the second well adapted to receive a second battery of the plurality of batteries in a second orientation, the second well including a second set of charging contacts, the second set of charging contacts having a second spacing thereamong, the second set of charging contacts for mating with a second set of battery contacts of the second battery when the second battery is received and delivering the charging current to the second battery; and

a second pocket adapted to receive a battery powered electronic device having a third battery of the plurality of batteries attached thereto, the second pocket including a first connector for mating with a second connector of the battery powered electronic device when the battery powered electronic device is received and delivering power to the battery powered electronic device so as to charge the third battery.
