1.Brief Introduction
DI-215 series battery storage testers are used for activated style lead-
acid storage battery, along with checking the following conditions of the
battery, starting up, charging, and electrical loading. With great design, easy
operation, precise reading, complete functions, this tester supply the
readings by a large LCD and hints by sound and light when testing. Precise
circuit and strong digital processing unit make it complete collection of a
series of complicated data and figure out every test data, which availably by
4-wire Kelvin test connection. Besides it strengthens input protection inside ,
in order to prevent such situations as polar reversal connection , over-high
voltage input, poor contact of the test clamps and so on. That makes sure
safer and more convenient when testing.
This tester is the best tool for battery sales, vehicle repair and condition
check of all kinds of lead-acid batteries that used in equipment system
associated with lead-acid battery.
2.Safety Rules And Attentions
This manual includes instruction, operation warning and maintenance. It
is possible to damage the tester without regulations in this manual. This
tester is designed and produced strictly according to GB4793.1 electronic
measurement instrument safety requirement and IEC/EN61010-1 safety
standard. It also reach double insulation over voltage standard CAT

and pollution degree 2 .
(1) DI-215 is available to vehicle of 12V storage battery, DI-215A is suitable
for testing 12V and 24V lead-acid storage battery.
(2) The working voltage of DI-215 is DC 9V to 18V, while that of DI-215A
refers to DC 9V to 35V. Make sure do not check the series connection battery.
(3) The voltage value will be higher than that in the normal situation after the
checked battery being fully charged . Please turn on the headlights for 2 to 3
water), on the contrary shorten its life fast for the reason that it will increase
the acidity of battery water, not the voltage however.

Reserve Capacity
Every storage battery has the ability to load averagely 25A electric
perminute and maintains lowest 10.5V more or less in the situation of
80°F(27°C).

for 30 seconds and maintain the lowest
voltage of 7.2V. The unit of CCA is Ampere. For some vehicles, especially
long time used ones, it is hard to start the engine smoothly, and has to be
done twice or for some seconds. Actually the electricity consumes most
when starting the engine. The voltage drops off from the normal value 12.5V
to 10.5V even lower at the moment that large current discharge shortly. The
large CCA is very helpful to start the engine smoothly.
★
CA
－
Cranking Ampere
The main meaning is very close to that of CCA. The unit is Ampere also.
The temperature under testing is the only one difference between them. CCA
refers to the result that measured under -17.8°C, and CA refers to the result
that measured under 0°C. If there indicates both CCA and CA on the battery,
CCA value is lower for the reason that the lower temperature is, the worse
battery works.

Ampere Hour
This is a standard written by Japanese Industrial Standard (JIS). It is
explained that the battery discharges with a fixed ampere for 20 hours along
with over 10.5V. Therefore the value multiplied by a fixed ampere and the
number of hour is Ampere Hour. For example a battery discharges with 5
ampere fixed for 20 hours, its Ampere Hour is 100.
