Suitable users and limits

Owners of a tas DR-1 or GT-R1 needing a fresh power source will find this a direct fit. Buyers with other device models or different part numbers should look elsewhere because the connector and form factor are specific to the listed tas units.

Questions about this item

Should I pick the 1800mAh 3.7V version or a different capacity for my DR-1?

This is the only capacity offered for the DR-1 and GT-R1 models; it matches the original BP-L2 specification of 1800mAh at 3.7V.

What does the 6.6Wh rating mean for actual runtime in my device?

The 6.6Wh rating equals 1800mAh at 3.7V; real runtime depends on your device's power draw but this capacity matches the factory battery.

Does the built-in protection circuit limit charging current or voltage?

The pack includes overcharge, over-discharge, over-voltage and short-circuit protection to keep charging within the 3.7V lithium chemistry limits.
