On these economy chargers, the full-charge detection may occur immediately after a given voltage peak is reached or a temperature threshold is detected. These chargers are commonly promoted on the merit of short charge time and moderate price. Figure 4-2 summarizes the characteristics of the slow charger, quick charger and fast charger. A higher charge current allows better full-charge detection. 1C Slow Charger 14h 0°C to 45°C (32°F to 113°F) Fixed timer. Subject to overcharge. Remove battery when charged.
During prolonged float charge, a periodic topping charge, also known as an ‘equalizing charge’, is recommended to fully charge the plates and prevent sulfation. An equalizing charge raises the battery voltage for several hours to a voltage level above that specified by the manufacturer. Loss of electrolyte through elevated temperature may occur if the equalizing charge is not administered correctly. Because no liquid can be added to the SLA and VRLA systems, a reduction of the electrolyte will cause irreversible damage.
The charge time on a battery that is partially discharged or cannot hold full capacity due to memory or other degradation is shorter accordingly. 4. During the first 70 percent of the charge cycle, the charge efficiency of a NiCd battery is close to 100 percent. Almost all of the energy is absorbed and the battery remains cool. Currents of several times the C-rating can be applied to a NiCd battery designed for fast charging without causing heat build-up. Ultra-fast chargers use this unique phenomenon and charge a battery to the 70 percent charge level within a few minutes.
