1. Kev ntsuas hluav taws xob
12V System: Them yog tias qhov hluav taws xob zoo li qub qis dua 12.4V; them tam sim yog tias qis dua 12.0V.
Ntev -Lub sij hawm Cia: Them yog tias qhov hluav taws xob qis dua 11.8V ua ntej pib.
2. Muaj Peev Xwm thiab Kev Tshawb Fawb
Capacity Test: Them lossis hloov yog tias lub peev xwm qis dua 80% ntawm tus nqi ntsuas.
Dedicated Tester: tuaj yeem ntsuas qhov voltage, muaj peev xwm, thiab kev tiv thaiv sab hauv, muab kev ntsuas raws li kev ntsuas.
Qhov taw qhia teeb: Qee cov khoom siv muaj lub teeb qhia lub zog; ntsuab qhia tag nrho cov nqi, liab / daj qhia tias yuav tsum tau them.
3. Tshawb xyuas kev ua haujlwm
Pib nyuaj: Lub cav khiav qeeb lossis tsis pib.
Cov cuab yeej ua haujlwm tsis zoo: lub teeb tsis pom kev, lub suab qis, ua haujlwm qeeb ntawm lub qhov rais fais fab thiab qhov rooj.
Txo Lub Sijhawm Siv: Txo cov sij hawm siv tsawg heev hauv - qhov kub thiab txias.
4. Kev tshuaj xyuas lub cev
Pom zoo: Tshawb xyuas lub roj teeb casing rau kev puas tsuaj, deformation, to, los yog corrosion.
Chaw nres nkoj soj ntsuam (yog tias tam sim no): Ntsuab qhia tias them nqi txaus, dub qhia tias xav tau them, thiab pob tshab lossis lub teeb daj qhia tias lub roj teeb yuav luag tag lossis lub roj teeb lub neej ze rau qhov kawg.
5. Kev ntsuam xyuas dav
Kev Saib Xyuas Tsis tu ncua: Nws raug nquahu kom ua qhov ntsuas hluav taws xob txhua hli thiab ntsuas lub peev xwm peb lub hlis twg.
Environmental Factors: Roj teeb muaj peev xwm txo qis hauv - qhov kub thiab txias, yuav tsum tau kuaj xyuas ntau zaus.
