Using a Battery Tender: Best Practices
A battery tender is a must-have for winter battery care—it’s a smart charger that keeps batteries topped up without overcharging. Begin by selecting a charger compatible with your battery type: traditional acid batteries and newer lithium batteries often require different charging profiles. Connect the tender’s clamps to the battery terminals, ensuring the positive (red) and negative (black) are matched correctly. Place the charger on a stable surface and switch it on; modern smart chargers will monitor voltage, automatically shifting to maintenance or “float” mode once the battery is full, thus preventing overcharge and avoiding battery damage.
Leave the battery tender connected throughout the winter months, especially if your motorcycle sits unused. A quality battery charger will adjust to minor discharges from clocks or alarms (parasitic drain) and maintain steady battery charge. For lithium batteries, always double-check that your charger model is listed as compatible—using the wrong charger can permanently damage your battery. This approach safeguards your investment and greatly increases the chances of your battery surviving winter storage without issue.

Comparing Battery Types: Lead-Acid vs. Lithium Batteries Performance in Winter
Choosing the right battery is an important decision for winter resilience. Lead-acid, AGM, and lithium batteries all have distinct pros and cons when it comes to cold-weather performance and winter storage. Lead-acid batteries are the standard for most riders due to their reliable power delivery and cost-effectiveness, but they generally require regular trickle charge maintenance and are susceptible to sulfation if stored discharged or in cold, damp environments. Lithium batteries, by contrast, boast longer lifespan and lighter weight, but their internal chemistry can struggle at low temperatures, making them harder to charge and susceptible to rapid voltage drop if improperly maintained.
