The range of special High Discharge models offer excellent characteristics for applications that require very high discharge rates. Designed for a functional life of 4-5 years at 25ºC in backup applications, these batteries are ideal for space limited applications requiring more power than can be delivered by a standard battery. For example, the 9Ah version has dimensions equal to those of a standard 7Ah but delivers nearly 30% more power while the HR 33Ah comes in the shape of a standard 28Ah battery.
The pbq 22HR-12 is a 22Ah battery especially designed for customer requiring a battery in the shape of a standard 17Ah but with increased capacity. Imagine the case where you change your computer system and find out that a controlled shutdown takes longer that your UPS is able to deliver! Just exchange the standard batteries with the pbq 22HR-12 and you instantly gain more backup time. Being able to deliver a 100A current during 5 minutes and even much higher start-up currents makes this battery also ideally suited as a stand-by power source for electric motors, cooling equipment etc.

The 15HR-12 is a very popular model for electric bikes and scooters since it is shaped like a standard 12Ah but offers 25% more capacity and is able to cope with the high inrush currents usually associated with electric motors. With an internal resistance of less than 12mOhm the voltage during discharge remains higher than when using standard 12Ah cyclic or stand-by, batteries. The compact form-factor ensures that this battery can be used as a direct replacement for standard 12Ah batteries.

In order to keep grid-corrosion and current per cm2 at acceptable levels, the pbq HR Discharge batteries are constructed around a larger area for both positive and negative material. This is done by adding extra plates in the same volume. Rather than use electrolyte with a higher specific gravity, a method rejected by pbq since this will reduce the functional life of the batteries to unacceptable levels.

Typical applications:

• UPS systems
• Wheel chairs, golf charts
• Electric bikes, scooters and other vehicles
• Tools
• (emergency) lights, pumps and valves
