Centenex Electronics DS-CS-SDP445SL 7.4V 2200mAh Li-ion GPS Battery

Compatible Graphtec Data-Logger Battery

This replacement cell powers Graphtec B-517, GL220, GL200A, GL450, GL500A, GL800E, GL820E and GL900E models. It also fits SEIKO DPU3445 printers using part numbers B-517 or BP-3007-A1-E. The 7.4 V lithium-ion pack delivers 2.2 Ah capacity in a white housing. Installers receive a single unit ready for immediate use.

Steady 16.28 Wh Output Over Long Sessions

The lithium-ion chemistry maintains stable voltage during extended logging runs rather than fading after a short burst. At 2200 mAh the pack supports continuous recording across multi-hour field deployments. Its 70.30 x 38.30 x 20.70 mm footprint slides into the original battery bay without modification. Users report consistent performance from first charge to end of cycle.

2.2 Ah Capacity Decides Fit for Your Logger

The 2.2 Ah rating is the single figure that determines whether this cell matches your device's runtime requirement. Loggers demanding higher capacity will need a larger pack not offered here. Buyers who need more storage for longer unattended surveys should verify the amp-hour spec before ordering. This unit serves exactly the models listed and no others.
