Men selvafladningen er stærk temperaturafhængig.
 
Almindelige [[NiMH]]-akkumulatorer taber 5-20% den første dag og taber derefter eksponentielt ca. 0,5-4% af ladningen per dag afhængig af opbevaringstemperaturen,<ref>[http://www.seabird.com/pdf_documents/manuals/NiMH_004.pdf Nickel-Metal Hydride (NiMH) Battery Charger and Battery Pack. User’s Manual. Sea-Bird Electronics, Inc.] Citat: "...NiMH batteries self-discharge up to 20% in the first 24 hours after charging, then as much as 15% per month. Self-discharge is highly temperature dependent. NiMH batteries self discharge about three times faster at 40&nbsp;°C than at 20&nbsp;°C. Age also effects self discharge. Older battery packs self-discharge faster

17% tab per måned svarer til ca. 0,6% per dag: (<math>100*(1 - \sqrt[30]{ 1 - 0,17 })</math>%), eller ca. mellem 0,5-1% om dagen. LSD NiMH derimod taber som tidligere nævnt ca. 20% over 6 måneder, hvilket svarer til ca. 0,12% per dag: (<math>100*(1 - \sqrt[180]{ 1 - 0,20 })</math>%).

NiMH-akkumulatorer med lav selvafladning kan langt de fleste steder erstatte brunstenbatterier og alkalinebatterier i f.eks. [[Ur (kronometer)|ure]],<ref name="stefanv"/>, [[transistorradio]]er, [[kamera]]er, og [[fjernbetjening]]er,...
