FAQ:
Q: Does a trickle charger really work?
A: Trickle charging works well when you have to put your vehicle away in the winter and also in emergencies. Your car battery will be connected to the trickle charger and that ensures that the battery won’t lose its charge even when it is not being used often.
Q: When to use trickle charger?
A: Trickle chargers are especially useful if you have an older car, a weaker or older battery, or just want peace of mind. Trickle chargers work by releasing a small amount of current to match a battery’s natural self-discharge rate to keep it topped up at its fully charged level.
Q: Should I use a trickle charger?
A: Basically, trickle chargers help the battery maintain power and stop self-discharge. Batteries slowly drain when not in use. Using a trickle charger can help keep batteries strong even during winter storage. Trickle chargers use electricity to replenish batteries at the same rate as the self-discharge.
Q: Is there danger from trickle chargers?
A: Some trickle chargers can safely be left connected for months without doing harm to your battery, providing an easy long term battery maintenance strategy. Others may only be left connected for a few days at most. Be sure to check your trickle charger’s manual for details.
