Q

How to determine a VRLA battery is fully charged while charging with constant-voltage limited-current method?

A

Two standards: 1. Charge time reached 18~24 hours (for non-deep discharge such as 20% DOD discharge, the charge time can be shortened to 10 hours); 2. The charge current drops to minimum value and lasted for 3 hours.

Q

Why VRLA battery will generate heat while charging?

A

While charging, a part of electric energy is converted into chemical energy, and another part of electric energy is converted into heat and other energies. Generating heat is a kind of normal phenomenon, but you need to be vigilant when temperature elevation is too high. It might be caused by large charging current or internal short circuit.

Q

Are lead acid batteries recyclable?

A

Lead acid batteries are 100% recyclable. Lead is the most recycled metal in the world today. The plastic containers and covers of old batteries are neutralized, reground and used to the manufacture of new battery cases. The electrolyte can be processed for recycled waste water uses. In some cases, the electrolyte is cleaned and reprocessed and sold as battery grade electrolyte. In other instances, the sulfate content is removed as Ammonia Sulfate and used in fertilizers. The separators are often used as a fuel source for the recycling process.
