Understanding the Trickle Charge Effect
August 26th, 2009In our 7500 series sound systems (Beacon, Liberty and Explorer) we’ve added what we like to call a safe or “trickle” charge mode. Often times you might need to operate one of these sounds systems all day, completely draining the battery. Knowing that one of the best ways to extend the life of the batteries is to charge them as soon as possible after use, you plug the system into a nearby power outlet.
If the batteries are very low or completely drained you will notice that none of the charge status lights turn on. No need to panic. This just means the internal charger is operating in “trickle” charge mode. This mode can take several hours to bring the batteries up to a point where normal charging will begin, making one of the charge status lights start to glow.
Leaving the unit plugged in overnight is a good test to determine whether the batteries are defective. A defective battery will cause the charging circuit to remain in trickle charge mode indefinitely. The possibility of a defective battery is why the trickle mode exists. If full charging current is applied to a defective battery, you run the risk of overheating and destroying both batteries.
