PJ3/3 Plus Rechargeable Ni-MH Battery...Don't get caught without power - carry a spare! Use with PJ3 or PJ3 Plus. (Ships with PJ3 & PJ3 Plus kits) This black colored Ni-MH battery can be single charged for approximately 60 pages, or double charged for approximately 100 pages of printing. Same as green above, but for the new PJ3/3Plus models only because the connector is different and this battery is designed specifically for the PocketJet 3 series.
