Ngoba umthamo webhethri, ukumelana kwangaphakathi, ama-voltage namanye amanani wepharamitha awahambelani ngokuphelele, lo mehluko udala ukuthi ibhethri elinamandla amancane kakhulu ukuthi likhishwe ngokweqile futhi likhishwe ngesikhathi sokushaja, ukungenela umjikelezo omubi ngemuva komonakalo, kungene kumjikelezo omubi kakhulu ngemuva komonakalo, ungena emjikelezweni ononya. Ukusebenza kwebhethri elilodwa kuthinta ngqo izindleko zokukhokhisa kanye nokwehla kwebhethri lonke kanye nokuncishiswa kwebhethri.I-BAST PRECEASTION BETEPTIONS I-BETERNETE BERTETE BERTETRORTE, Ukuze uqinisekise ukuvumelana kwebhethri ngezinga elikhulu kakhulu, uthuthukise i-Battery Life Mileage futhi ubambezele ukuguga kwebhethri.
