Best battery charger for lawn mower: Buying guide
Now that we’re done with the reviews, it’s good to mention that not everything promoted as the best battery charger for lawn mower is equally good.
It has never been, anyway.
Still, every owner has a list of unique requirements they want a charger to meet.
To help you make the right choice, here is couple of the most vital aspects to keep in mind in your hunt for a worthy lawn tractor battery charger…
· Multiple mode charging settings
Having options such as slow charge, fast charging, and float maintenance mode helps you charge optimally according to your needs.
· Compatibility with your specific battery
Some chargers won’t work for certain battery types.
We recommend that you read the paperwork before ordering to see if it will charge your installed battery.
It should also have enough ‘bank capacity’ – most common are 6v and 12v battery chargers at this level.
· Durable construction
A rugged housing and other destruction-resistant qualities such as waterproofing make it a lasting investment.
· Ease of use
You certainly want a replacement unit that works a treat and recharges your battery with ease.
It should especially switch over to the different charging modes without bothering you much and stop on attaining full charge.
· Multiple protective features
For peace of mind, consider:
- Automatic temperature compensation- Though not available in all, this helps adjusts the current charging temperature to protect your battery from overheating and possible damage.
- Auto-safety-shutdown – Halts charging in case of problems like the terminal clip falling off.
- Integrated charging timer- This safety feature cut off charging after a fixed time. You’re well aware that an overcharge could easily ruin the battery.
- Hook-up protection- Checks for improper connections before beginning to charge.
· Additional Wished-for Features
Here is a checklist of extra “wish-to-have” qualities to be on the lookout for:
- More connection options – A unit providing multiple battery terminal connections is friendlier since you can use the option you find easier.
- Long cables- All the necessary hook up cords should be longer for operational convenience.
- Mounting brackets- This allows you to permanently mount it at a desired spot, if you so wish.
- A reasonable warranty- Anything beyond one year clearly indicates that the company is backing the product to last and work as advertised. You can also interpret it to mean that the product is of an exceptional standard.
The best way to make your life easy during the cold weather is by hooking up a quality battery charger to your lawn tractor’s battery.
When shopping, be sure to pick one with the ability to recharge your mower’s battery and with those features that suit your preferences.
The other option is, of course, the jump-start technique – provided you own a compatible battery- but it’s much more troublesome.
