3500mAh Battery Replacement for Husqvarna Automower 315X 315 310, Husqvarna 584 85 28-01, for Gardena Sileno Minimo/City/Life/Plus, Gardena Sileno R100Li/ R100LiC/ R130Li/ R130LiC/ R160Li Lawn Mower

What It Is

This is a 3500mAh lithium-ion battery replacement designed for Husqvarna and Gardena robotic lawn mowers. It powers the mower during autonomous operation, typically lasting 60–75 minutes per charge depending on mowing conditions.

Fitment & Compatibility

Before buying, confirm your mower model and existing battery part number. This battery directly replaces Husqvarna 584 85 28-01 and fits these Automower models: 315X, 315, 310. For Gardena, it works with Sileno Minimo, City, Life, Plus, and Sileno R100Li/R100LiC/R130Li/R130LiC/R160Li. Measure your original battery—this is a standard size (approx. 4.7 x 2.5 x 1.2 inches) and uses the same 3-pin connector. It is an aftermarket replacement, not OEM, so verify the connector shape matches your mower’s battery bay.

Key Things to Know

• Quality & safety: Aftermarket batteries may lack overcharge protection circuits found in OEM units. Check for UL or CE certification marks to reduce fire risk.
• Installation: No tools required—slides in/out of the battery compartment. Ensure the mower is powered off and the charging station is disconnected before swapping.
• Run time vs. OEM: The 3500mAh capacity is slightly higher than the standard 3000mAh OEM battery, giving you 10–15 extra minutes of mowing time in light grass.
• Gotcha: Some users report the battery indicator light on the mower may not show accurate charge level with aftermarket batteries. Test your mower’s behavior after installation.

Should You Buy It

If your original Husqvarna or Gardena robotic mower battery has degraded (run time under 40 minutes) and you’re comfortable with an aftermarket part, this is a cost-effective drop-in replacement. It’s a good fit for DIY owners who want a small run-time boost without paying OEM prices. Avoid if you need guaranteed compatibility with battery monitoring systems or prefer official warranty support.
