由電池決定。在沈陽對講機日常使用中，對講機電池是屬于損耗件，隨著使用時間、頻率的增加會減弱其使用性能; 究竟如何判斷對講機電池能否繼續使用或者是更換新的電池呢?

一(yi)、對講機電池(chi)的使用壽命

電(dian)(dian)(dian)池的(de)使用(yong)壽命一(yi)般由電(dian)(dian)(dian)池“充(chong)--放”電(dian)(dian)(dian)循環次數衡量，通常為300-500次， 所以應盡量避(bi)免電(dian)(dian)(dian)池有余電(dian)(dian)(dian)時(shi)(shi)充(chong)電(dian)(dian)(dian)，和未充(chong)滿電(dian)(dian)(dian)時(shi)(shi)使用(yong)，這樣會縮短電(dian)(dian)(dian)池的(de)壽命，做(zuo)到(dao)用(yong)完(wan)再充(chong)，充(chong)滿再用(yong)。

二、對(dui)講機電池(chi)的儲存

對講機電(dian)池需(xu)要長(chang)時(shi)間擱置(zhi)存放(fang)時(shi)，請先將(jiang)電(dian)池預充電(dian)50%左右電(dian)量，這樣(yang)有利于防止(zhi)電(dian)池的性能衰(shuai)減，影響(xiang)日(ri)后(hou)使用。對講機關(guan)機時(shi)間超過(guo)7天(tian)時(shi)，應先將(jiang)對講機電(dian)池完(wan)全放(fang)電(dian)，充足電(dian)后(hou)再(zai)使用。

三(san)、對講電池充電環境(jing)

對講(jiang)機電池(chi)充電應在5-40℃的(de)環境(jing)中(zhong)進行(xing)，如果(guo)超過此溫度范圍，電池(chi)壽(shou)命(ming)會(hui)受(shou)到(dao)(dao)影響，同 時有可能(neng)充不滿額定(ding)容量。不要將(jiang)電池(chi)暴(bao)露在高溫或嚴寒下，像三(san)伏(fu)天時，不應把對講(jiang)機放在車里，經受(shou)烈日的(de)暴(bao)曬;或拿到(dao)(dao)空調房中(zhong)，放在冷氣直吹的(de)地方(fang)。

四、對講機電池充電注意事項(xiang)

對講機電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)前(qian)，鋰(li)(li)電(dian)(dian)(dian)池(chi)不(bu)需要專(zhuan)門放電(dian)(dian)(dian)，放電(dian)(dian)(dian)不(bu)當(dang)反而會(hui)(hui)損(sun)(sun)壞電(dian)(dian)(dian)池(chi)，充(chong)電(dian)(dian)(dian)時盡(jin)量以慢充(chong)充(chong)電(dian)(dian)(dian)，減少快充(chong)方式;使(shi)用原廠充(chong)電(dian)(dian)(dian)器，鋰(li)(li)電(dian)(dian)(dian)池(chi)要用鋰(li)(li)電(dian)(dian)(dian)池(chi)專(zhuan)用充(chong)電(dian)(dian)(dian)器，并(bing)遵照指示說明，否責會(hui)(hui)損(sun)(sun)壞電(dian)(dian)(dian)池(chi)，甚至(zhi)發生危險。

五(wu)、對講機電池使(shi)用注(zhu)意事項

對講機電池在5-5-90(即5%發射信(xin)號(hao)(hao)，5%接收(shou)信(xin)號(hao)(hao)，90%待機)情況(kuang)下使用一般都可達到8小時，并視電池的容(rong)量、質(zhi)量、使用頻率(lv)而有所不同。

如(ru)何(he)測(ce)試對(dui)講機電池能(neng)否使用?

1、將(jiang)萬用(yong)表按正確的位置放好(hao)，水平或垂直放置。

2、對(dui)講機電池上有-和+號。-表(biao)示(shi)(shi)負(fu)(fu)極(ji)，萬用表(biao)一般是(shi)黑線(xian)，地線(xian)。+表(biao)示(shi)(shi)正極(ji)，萬用表(biao)一般是(shi)紅線(xian)。電源(yuan)和負(fu)(fu)載的極(ji)性不(bu)能互(hu)換(huan)。

3、在(zai)操作過程中要(yao)注意首先注意萬(wan)用表的表筆要(yao)注意極性，即(ji)紅(hong)+，黑-。確認后(hou)再扳(ban)量程開關到直流電(dian)壓檔,就是(shi)V下有-的位置。這(zhe)個量程有8檔位。熟(shu)悉萬(wan)用表后(hou)就知道所測元件該在(zai)哪個范圍選擇。所以1.5V在(zai)直流10V檔位。

4、測對講(jiang)機電池(chi)的電壓。紅(hong)表(biao)(biao)筆接(jie)觸對講(jiang)機電池(chi)的正極觸點，黑表(biao)(biao)筆接(jie)觸電池(chi)負(fu)極。千萬不能(neng)錯。

結論：

如(ru)(ru)果電(dian)(dian)(dian)(dian)壓在(zai)正(zheng)常使用(yong)范(fan)圍(wei)可以將(jiang)電(dian)(dian)(dian)(dian)池充滿電(dian)(dian)(dian)(dian)，如(ru)(ru)果充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓沒變化說明(ming)保護板及充電(dian)(dian)(dian)(dian)器損壞;如(ru)(ru)使用(yong)為(wei)鋰電(dian)(dian)(dian)(dian)池標稱電(dian)(dian)(dian)(dian)壓7.2V滿電(dian)(dian)(dian)(dian)為(wei)8.4V，擱置后電(dian)(dian)(dian)(dian)壓為(wei)8.3V左右(you)，如(ru)(ru)果正(zheng)負極電(dian)(dian)(dian)(dian)壓為(wei)0V或者小于6V說明(ming)電(dian)(dian)(dian)(dian)池已(yi)經過放電(dian)(dian)(dian)(dian)損壞。

綜上所述，大家在使(shi)(shi)用(yong)對講機時(shi)，如(ru)果要(yao)知道(dao)該電(dian)池是否能使(shi)(shi)用(yong)或者需(xu)要(yao)更換(huan)，可以按照上面的方法進行測試。
