If you own a battery powered garden tool like a cordless lawn mower, hedge trimmer or leaf blower, you have probably wondered: Should I leave the battery charged all the time? It is a common question and while there is no one size fits all answer, understanding the pros and cons can help keep your equipment ready to go.
So, Is It Safe?
In short, yes, it generally is. Most models come with smart charging systems. These built in protections stop the battery from overcharging, overheating or drawing unnecessary power once it is fully charged.
That means leaving the battery on the charger overnight or even for a few days is unlikely to cause any harm.
The Convenience Factor
One of the biggest benefits of keeping your battery topped up is convenience. When your battery is always fully charged, your tools are ready whenever you are. No frustrating delays halfway through mowing the lawn or trimming the hedge.
This is especially handy during the peak growing season when free time is short, and garden jobs build up quickly.
Battery Health Still Matters
Even though batteries are robust, there are still a few best practices that can help extend their lifespan.
Just like your phone or other devices, garden batteries benefit from the occasional full discharge and recharge cycle. Most manufacturers recommend doing this every few months to keep the battery working properly.
Also, another important point to note is not to charge a battery when it is hot. For example, straight after use.
Let it cool down first as heat is a high factor in battery degration.
Do You Need to Keep It Plugged In?
The honest answer is no; you do not. While it's safe to leave your battery on charge, it is not necessary. But for storing it for extended periods there a bi tmore you should know.
If you prefer to charge it when needed and store it separately, that is completely fine. Just avoid letting it go completely flat and sit unused for weeks. That is one of the quickest ways to damage or reduce its life span.
If you are putting your battery away for an extended period, such as over winter, aim to store it at around 50 percent charge in a cool dry location, preferably indoors and not in a sweltering shed or damp garage.
Final Thoughts
So, should you keep your garden battery permanently charged?
Whether you are a weekend gardener or a landscaping enthusiast, the aim is the same: reliable tools, healthy batteries and a tidy garden.
For optimal long-term performance, it is wise to occasionally let the battery fully discharge and recharge and avoid heat where possible. To store for extended periods, it's recommended to store with at least 50% charge to reduce battery degradation.
