  • 3400mAh capacity delivers 62.90Wh for extended mowing sessions
  • 5V output matches original battery specifications exactly

Compatible replacement battery

This 18.5 V lithium-ion pack delivers 3400 mAh and 62.90 Wh for Gardena Mahroboter Sileno, Sileno + and R100Li through R160Li models. It fits the listed robotic mowers and the Sileno+ 4050 vacuum without modification. A new fully decoded chip communicates with the original electronics for correct charge reporting. Installation follows widely available online guides.

Upgrade from depleted original cells

When the factory pack no longer holds enough charge for a full mowing cycle, this unit restores runtime to the original specification. The jump is worth it if the mower stops early, reports a battery fault or requires daily recharging. ISO9001, RoHS and CE certification confirm the cell quality matches OEM requirements. Three full charge and discharge cycles settle the pack to peak capacity.

Sustained discharge in outdoor use

The 266.0 g pack measures 92.00 x 67.90 x 22.40 mm and operates reliably up to 60 °C ambient temperature. Under continuous mowing load the voltage remains stable until the protection circuit triggers a safe shutdown. Storage above 60 °C is not recommended and will accelerate ageing. The construction resists vibration and moisture typical of garden environments.

Questions about this item

Will the 92.00 x 67.90 x 22.40 mm pack fit my Gardena Sileno mower battery compartment?

The pack matches the original dimensions of 92.00 x 67.90 x 22.40 mm, so it fits the Sileno, Sileno+, R100Li, R130Li and R160Li battery bays without modification.

What is the installation step users most often miss when fitting this 18.5 V replacement?

Align the connector fully and press until it clicks; a partial seat leaves the circuit open and the mower will not start.

When should I replace the 3400 mAh pack in my R160Li?

Replace it when a full charge no longer completes the usual mowing cycle or run time falls well below the original level.
