348021XL Replacement 12 V Sealed Rechargeable Battery Base

The 3480 was a replacement base for our 21XL Microloggers; the "L" in 21XL indicated the logger had this base. The 3480 included an anodized base, on/off switch, internal, sealed rechargeable battery, LED, A/C charging circuitry (pn 3479), which included a socket for connection of external solar panel or ac transformer (pn 272). For 220 Vac operation, the 272 required the VC273 transformer.

The 3480 was also known as the LA21X. It was retired on March 17, 2009.
