Does it really work?
The term “trickle charger” refers to a battery charger that charges at a low amperage.
Some are also designed to be left connected long-term without overcharging.

So when you hear people talk about trickle chargers, that’s typically what they’re referring to.
As to why you should charge your battery instead of driving it around, there are two issues.
The other issue is thatalternators aren’t designed to charge completely dead batteries.
Next, plug the charger into an outlet and turn it on.
Applying excess charge amperage can generate heat, and may cause off-gassing.
In extreme cases, it’spossible for a battery to explode.
To prevent this, smart trickle chargers can detect the charge level and automatically adjust the amperage.
Who Needs a Trickle Charger?
In most cases, a trickle charger is more of a luxury than a necessity.
However, they aren’t expensive, and it’s a nice tool to have around.
