BAT 135 Battery Tester

BAT 135 | REV. A | JANUARY 2018

Starting, Lighting, Ignition (SLI) Battery
A battery that performs three basic functions on all normal vehicles. Batteries given this description will have been 

specifically designed for service on cars and trucks within a voltage controlled electrical system. Those SLI batteries 

which are intended for heavy haulage vehicles fitted with large diesel motors may often be called COMMERCIAL 

batteries. They have to be much more powerful and more robust than batteries intended for cars.

State of Health (SOH)
Percent of battery capacity remaining compared with the marked original battery capacity.

State of Charge (SOC)
Percent of battery actually charged.

Cold Cranking Amps (CCA)
The current in amperes which a new fully charged battery can deliver for 30 seconds continuously without the termi-

nal voltage falling below 1.2 volts per cell, after it has been cooled to 0 degrees F and held at that temperature. This 

rating reflects the ability of the battery to deliver engine starting currents under winter conditions.

Ampere-Hour
The unit of measurement of electrical capacity. A current of one ampere for one hour implies the delivery or receipt 

of one ampere-hour of electricity. Current multiplied by time in hours equals ampere-hours.

Warranty Terms and Conditions

Any battery tester found defective in material or workmanship within one year from the date of purchase by a retail 
customer will be repaired or replaced according to published defective return test repair procedures. The existence 
of a defect shall be determined by the manufacturer in accordance with published warranty repair procedures. The 
warranty repair procedures are available upon request.

This warranty does not cover any unit that has been damaged due to accident, abuse, alternation, use for a purpose 
other than that for which it was intended, or failure to follow operating instructions. This warranty is expressly 
limited to original retail buyers. This warranty is not assignable or transferable. Proof of purchase is required for all 
alleged claims. Warranty cannot be authorized without proof of purchase. Warranty claims must be sent pre-paid 
with dated proof of purchase. Damage incurred during shipment is the responsibility of the shipper (customer 
returning unit) If the returned unit qualifies for warranty, the shipper will only incur shipping cost. The manufacturer 
reserves the right to substitute or offer alternative warranty options at its discretion.

The sole and exclusive remedy for any unit found to be defective is repair or replacement, at the option of the manu-
facturer. In no event shall the manufacturer be liable for any direct, indirect, special, incidental, or consequential 
damages (including lost profit) whether based on warranty, contract, tort, or any other legal theory.

Return Goods

Pack with sufficient over-pack to prevent damage during shipment. Damage incurred during return shipment is not 
covered under this warranty. Repair costs for such damages will be charged back to shipper.
