![]() ![]() If we take the pessimistic numbers, then 98% of the charge is lost after a year. Taking the optimal numbers (5% first day, 0.5% per day), we get 10% of the charge lost after a week, 20% lost after a month, 40% lost after 3 months, and 85% of the charge lost after a year. The self-discharge is 5-10% on the first day, and stabilizes around 0.5-1% per day at room temperature. ![]() ![]() Nyh ( talk) 14:26, 18 February 2009 (UTC) Reply Īnother quote from Nickel-metal hydride battery: I don't know what to replace it with, though. So, I think the first sentence quoted above is wrong. Some measurements I see now at the end of this talk page claims that the standard batteries only return 40% of the charge after just 3 months, coming out to retaining just 3% of the charge after 12 months, which is much similar to my personal experience. After a year, standard NiMH batteries that I owned usually lost *all* their charge, not just half. In my experience, I think the first sentence got it wrong. If the first sentence is correct, then ordinary NiMH batteries lose only half their charge in a year, so they will surely "last up to a year" which the second sentence says they don't. the batteries retain 70 to 85% of their capacity after one year when stored at 20 ☌ (68 ☏), while standard NiMH batteries may lose half their charge in this time period.Due to the low self-discharge, they (LSD NiMH batteries) are also suitable for long-term intermittent or low-current uses they might last up to a year between charges, much better than ordinary NiMH batteries. The article currently contains the following two sentences in the beginning: ![]()
