LEAD ACID BATTERY

Lead acid battery does not like deep cycling. A full discharge causes extra strain and each cycle robs the battery of some service life. This wear-down characteristic also applies to other battery chemistries in varying degrees. To prevent the battery from being stressed through repetitive deep discharge, a larger battery is recommended. Lead-acid is inexpensive but the operational costs can be higher than a nickel-based system if repetitive full cycles are required.

The lead-acid battery has one of the lowest energy densities, making it unsuitable for portable devices. In addition, the performance at low temperatures is marginal. The self-discharge is about 40% per year, one of the best on rechargeable batteries. In comparison, nickel-cadmium self-discharges this amount in three months. The high lead content makes the lead-acid environmentally unfriendly.

Plate thickness

The service life of a lead-acid battery can, in part, be measured by the thickness of the positive plates. The thicker the plates, the longer the life will be. During charging and discharging, the lead on the plates gets gradually eaten away and the sediment falls to the bottom. The weight of a battery is a good indication of the lead content and the life expectancy.

The plates of automotive starter batteries are about 0.040″ (1mm) thick, while the typical golf cart battery will have plates that are between 0.07-0.11″ (1.8- 2.8mm) thick. Forklift batteries may have plates that exceed 0.250″ (6mm). Most industrial flooded deep-cycle batteries use lead-antimony plates. This improves the plate life but increases gassing and water loss.

Safety valves allow venting during charge, discharge and atmospheric pressure changes.

Sealed lead-acid

Driven by different market needs, two lead-acid systems emerged: The small sealed lead-acid (SLA), also known under the brand name of DROM POWER, and the larger Valve-regulated-lead-acid (VRLA). Both batteries are similar. Engineers may argue that the word ‘sealed lead-acid’ is a misnomer because no rechargeable battery can be totally sealed.

The sealed lead-acid battery is rated at a 5-hour (0.2) and 20-hour (0.05C) discharge. Longer discharge times produce higher capacity readings because of lower losses. The lead-acid performs well on high load currents.

We offer a complete selection of 12V sealed lead acid batteries. SLA batteries are used in a wide variety of applications, including UPS battery backups, generators, golf carts, and more. These batteries are rechargeable, completely sealed and maintenance free. We also offers a lot of different 6V sealed lead acid batteries. Our batteries range in capacity from 500 mAh to 200 Ah, fitting thousands of applications. 6 volt SLA batteries are extremely popular in backup power supplies, like UPS backup units, and home alarm systems.
