Peugeot 308: Check - recharge : Service battery tester "E-XTEQ"

ESSENTIAL : Observe the safety and cleanliness recommendations .

ESSENTIAL : All personnel carrying out work on a vehicle fitted with traction batteries must have received specific electric vehicle training and be authorised to work on these vehicles (observe the regulations in force in the respective country).

Only a battery tester can diagnose the general condition of the ancillaries batteries. This tester not only diagnoses the ancillaries battery charge status, but also their ability to be recharged.

The diagnostic tool permits :

• Measuring the ancillaries batteries voltage (Ancillaries batteries charge status)
• Measuring the ancillaries batteries conductance (Capacity of the ancillaries batteries to drain and to recharge themselves)

Measuring the ancillaries batteries voltage with a simple voltmeter does not allow you to evaluate the ancillaries batteries’ health status, nor their real recharging ability.

CAUTION : Perform the operations to be carried out before disconnecting or after reconnecting the ancillaries batteries .
