Frequently Asked Questions (FAQs)

Let’s ask and answer now some leading questions surrounding this wonderful topic of study:

Q. Can you overcharge a battery with a trickle charger?

A. YES, you can! If you leave the batteries unattended, there is the possibility of overstepping the voltage threshold of that battery. You should hence time the recharge duration in such a way as not to overstep the laid down limits.

Q. What is the difference between a trickle charger and a battery charger?

A. A trickle charger is slower than a normal battery charger. Then again, it supplies the electrical current steadily and continually irrespective of whether the level of charge is full or not. A normal charger will usually supply the electrical current if and only if the level of charge in the battery has dipped.

Q. Can you leave a trickle charger on all the time?

A. YES, you can! As we have already explained, this charger for a large part does not have the ability to sense the levels of charge and make appropriate adjustments. You hence have to leave it to supply the power continually and as need be.
