Sony BP MZ1 Battery replacement

Three alternatives to replace the BP-MZ1 battery.

1- Using 5 AAA NiCd rechargeable batteries

2- Using 2 AA Lithium-Ion batteries

3- Using 2 18650 Lithium-Ion batteries

Use 2 M2.5x10 screws

Cut two small L-shaped tin plates and insert them into the casing for the contacts, soldered to the wires. See photos

Updated:

• Added 2x18650 V2, best fit 

• Added Case Charger (Use a small rivet soldered to wire as contact, or simply make small ball tin of solder on the end of the wire and embed it with heat so that it protrudes) I use an iMAX type charger.
