How to store your Snapper batteries during winter

The temperatures are dropping, and the garden’s ready for winter—but what about your Snapper gear? Prepping your gardening equipment for the colder months is key to keeping everything in tip-top shape for spring, and proper battery storage is a big part of that.

This guide covers winter storage tips for both lead-acid and lithium-ion batteries, so your tools are ready to go when it’s time to get back in the garden come spring.

Winter storage for lead-acid lawn mower batteries

Snapper’s zero-turn mowers and lawn tractors typically use lead-acid batteries to start the engine. Here’s how to keep them in top shape through the colder months:

1. Use a trickle charger

If you can, we recommend keeping the battery connected to a trickle charger over winter. A trickle charger provides a steady low current. This prevents the battery from discharging, which helps extend its lifespan and ensures a smooth start-up in spring.

2. Remove the battery from your mower if needed

If your mower is stored in a shed or garage where temperatures might drop below freezing, or where it might get particularly humid, it’s best to remove the battery altogether. Start by disconnecting the negative (–) cable, followed by the positive (+) cable after which you can bring it indoors.

3. Store in a cool, dry place

Choose a spot where the temperature remains between 5 °C and 20 °C. Preferably away from direct heat sources. Think of a shelf in a dry basement, shed, or garage—anywhere with consistent temperatures is ideal.

4. Check the battery occasionally

Whether connected to a trickle charger or stored on its own, it’s helpful to check the battery’s charge periodically. If it’s not holding a charge, you’ll need to replace it.

Tip: If your lead-acid battery isn’t holding charge, Snapper’s authorised dealers can help you find the right replacement

Winter storage for 82V lithium-ion batteries

Snapper’s cordless tools—such as hedge trimmers, chainsaws, leaf blowers, and utility carts—use 82V lithium-ion batteries. These high-performance batteries need special care in cold weather to preserve their durability.

Here’s how to store these batteries to keep them in shape:

1. Remove the battery from your tool

Always remove the battery before storing your Snapper cordless tool for winter. This helps prevent potential damage to the tool if the battery would leak or corrode.

2. Clean and inspect the batteries

Before putting them away, you should clean each battery to remove any dirt, grass clippings, or debris. Wipe them down with a dry, soft cloth and check for any signs of wear or damage. Contact your Snapper dealer if replacements are needed.

3. Store at 40-60% charge

You should store lithium-ion batteries partially charged—around 40-60% charge is ideal. On the Briggs & Stratton 82V battery, this is indicated by two blue lights. This helps reduce strain on the battery cells and preserves long-term performance.

4. Store in a stable, dry environment

Find a location with stable, moderate temperatures above zero, free from moisture and direct sunlight. A cool, dry room like a basement or garage works well.

5. Check the battery occasionally

Although lithium-ion batteries have minimal self-discharge, it’s still wise to check on them once or twice over the winter. If the charge drops, recharge to 40-60% to avoid deep discharge, which can permanently damage the battery.

Tip: Don’t leave lithium-ion batteries on the charging station longer than necessary. Remove them when the battery is charged for operation or partially charged for winter hibernation.

By following these simple steps, you’ll keep your Snapper batteries in top shape through the winter. For more insights on winter prep, check out Snapper’s guide on preparing your ride on lawn mower for winter.
