Compatible replacement for Garmin Varia RTL510

This rechargeable lithium-polymer battery matches the original 361-00082-00 specifications. It fits the Varia TL, RTL510 and RTL501 models. The 950mAh capacity at 3.7V restores the radar tail light to factory runtime.

Built-in protection circuit and certified safety

Overcharge, over-discharge, over-voltage and short-circuit protection are integrated into the cell. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. No separate charger or adapter is included in the package.

Single-cell 3.7V chemistry limits series use

The 3.7V nominal voltage means the cell cannot be combined in series for higher-voltage devices. Capacity is fixed at 950mAh and 3.52Wh, so users needing longer runtime must carry a spare. Physical dimensions of 61.3 x 30.0 x 6.6mm prevent fitment in smaller compartments.

Questions about this item

How often will the Li-Polymer 950mAh cell need replacing under daily charge cycles?

Li-Polymer cells typically last several hundred full cycles; capacity will gradually drop below the rated 950mAh after extended daily use.

What capacity fade appears first during a continuous ride with the RTL510 light?

The 3.52 Wh pack will show reduced runtime once the 950mAh rating degrades under sustained discharge.

Does the 44.0g battery get warm during all-day operation on the Varia RTL501?

Normal operation stays within safe temperature limits; the built-in protection prevents over-voltage and short-circuit heating.
