Instantaneous Check on Battery Deterioration

In todays multimedia age, the maintenance of storage batteries used in information technology devices is taking on increased importance.
The 3550 series of BATTERY HiTESTERS can give instantaneous results on the state of a battery, on a three-rank scale of Pass, Warning, or Fail, using a composite decision based on the internal resistance and the voltage.
Choose from 3 models to suit your application: Model 3550 for testing medium-capacity alkali and lead-acid storage batteries, Model 3555 for compact storage batteries, and Model 3551 to reliably measure high-capacity alkali and lead-acid storage batteries.
