I have an early 2008 model still with its original battery. Model Information: Manufacturer: SMP Device Name: ASMB012 Pack Lot Code: 2 PCB Lot Code: 0 Firmware Version: 110 Hardware Revision: 500 Cell Revision: 200 Charge Information: Charge Remaining (mAh): 375 Fully Charged: Yes Charging: No Full Charge Capacity (mAh): 375 Health Information: Cycle Count: 832 Condition: Replace Now Battery Installed: Yes Amperage (mA): 146 Voltage (mV): 12599 but it's now in need of replacement. I am struggling to find one either at Apple or online retailers. Does anyone have a recommendation of what would be a suitable make/model? Thanks.
