The pbq 22HR-12 is a 22Ah battery especially designed for customer requiring a battery in the shape of a standard 12V 18Ah battery 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 HR 22-12 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.
12V 15Ah High Rate battery
The pbq HR 15-12 is a very popular model for electric bikes and scooters since it is shaped like a standard 12V 12Ah battery 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 12V 12Ah cyclic or stand-by batteries. The compact form-factor ensures that this battery can be used as a direct replacement for standard 12V 12Ah batteries.
High Rate battery technology
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 of High Rate batteries
Designed for a functional life of 4-5 years at 25ºC in backup applications, these AGM batteries are ideal for space limited applications requiring more power than can be delivered by a standard battery. Typical High rate battery applications:
