Charger Model: VOLVO After the initial charge DSE7210, automatic shutdown DSE5120, initial charging indicator light turns off DSE, only enough lights. (After the initial charge is no longer sufficient to equalize charge) * * initial charging concept: the first charge refers to the first dry put a new battery electrolyte is added after the first charge. Battery electric vehicle factory and some have been the initial charging DSE7110, only normal charging, such as initial charging operation performed, will result in decreased battery performance. Therefore, the user before the new electric vehicles purchased for the first time have had to charge the battery for related advice.
