Low self discharge nickel-metal hydride batteries, also known as LSD NiMH batteries, are designed to solve the problem of self-discharge that is common in traditional rechargeable batteries. Our company is a manufacturer of NiMH batteries, and our customers have very good feedback on our LSD NiMH batteries. Today we will learn more about LSD NiMH batteries. Batteries, regardless of their type, naturally lose their charge over time, even when not in use. This phenomenon is known as self-discharge. Self-discharge is due to a number of factors, and the rate of self-discharge varies depending on the battery chemistry and its structure. Traditional rechargeable batteries, such as NiCd (Nickel Cadmium) and older NiMH (Nickel Metal Hydride) batteries, are known to have relatively high self-discharge rates. This means that even if you fully charge these batteries and leave them idle for a period of time, they will gradually lose their charge, leaving you with a depleted battery when you need it most. Compared to these batteries, low self-discharge NiMH batteries have a much lower self-discharge rate. At NBCELL, our low self-discharge NiMH batteries have an ultra-low self-discharge rate. The battery capacity retention rate reaches 85% when placed in normal environment for one year. They are widely used in emergency lights, electronic instruments, medical equipment and mining industry.

The biggest leap forward in consumer rechargeable technology came with the development of Low Self-Discharge NiMH batteries — most famously, the Panasonic Eneloop line introduced in 2005. Before LSD NiMH existed, rechargeable batteries had a reputation problem: you'd charge them, store them, and find them dead when you actually needed them. LSD NiMH solved that. Classic NiMH vs. Low Self-Discharge NiMH — the Eneloop revolution · Standard NiMH batteries were powerful but notoriously impatient. Left in a drawer, they'd lose most of their charge within weeks. Different battery chemistries offer very different levels of self-discharge, lifespan, safety, and storage performance. Choosing the right type depends on how and where the battery will be used. ... The most widely available rechargeable format for AA and AAA batteries. In their LSD form, NiMH cells are ideal for TV remotes, game controllers, toys, wireless keyboards, digital cameras, smoke detectors, and clocks — any device that sits idle but must work reliably on demand. LSD NiMH batteries do come with one real trade-off: they typically offer around 20% lower rated capacity than the highest-capacity standard NiMH cells. Under low-stress, low-drain conditions — remotes, clocks, smoke detectors — this gap is noticeable on paper but barely felt in practice. Under high-stress, high-drain conditions like camera flash or power tools, the two types perform nearly identically, because peak discharge behavior is governed more by internal resistance than rated capacity.

This electrode is made from a metal hydride usually alloys of Lanthanum and rare earths that serve as a solid source of reduced hydrogen that can be oxidized to form protons. The electrolyte is alkaline potassium hydroxide. Cell voltage is 1.2 Volts. The low self-discharge nickel-metal hydride battery (LSD NiMH) was introduced in November 2005. These batteries were developed by Sanyo, who called them ”eneloop”. Subse- quently, other manufacturers also offered LSD NiMH. Low self-discharge (LSD) NiMH Batteries: This kind of battery reduces self-discharge and, therefore lengthens shelf life compared to normal NiMH batteries. Thick separators take up space and reduce capacity, while providing a low-tech way of reducing self discharge, while thin separators tend to raise the self discharge rate. Some batteries may have overcome this obstacle with more precise manufacturing techniques and by using a more advanced sulfonated polyolefin separator [64]. Specifications for the self discharge rate are not always clear or widely published, and virtually any LSD may claim to maintain some level of charge after 12 months.

LSD makes a HUGE difference - I feel comfortable using these in a flashlight, for TV remotes, - things where previously I would not have considered using rechargeables. However, I've never been able to find details on what they actually do to these batteries that makes them LSD - low self discharge. If anyone knows of a link to information about this, I'd really like to know! (& thanks) Some info about LSD batteries: LSD battery info ... They have a thicker separator in them to slow down self discharge. This takes up a little space so will be a little lower capacity due to that. Most lithium chemistry batteries already have very low discharge. LiFePO4 is a bit higher than some, around 4%/month, but that's still pretty reasonable for the typical devices they're used in, since their primary benefit is # of recharge cycles and if you need something with higher # recharge cycles, odds are it won't be long till they're drained from the load rather than self discharge. The USB recharge port on it broke, which was really annoying as that's also the easiest way to get the pics off, but an aftermarket charger was cheap, and it's not a big deal to take the SD card out, or they now make SD cards with wifi to transfer pics if I wanted to bother getting one but they are also much lower capacity and I like having the higher capacity for videos. ... >>I should have bought the Canon that took 4 x AA instead! Yep, I try to stick with models that take 4 AA batteries, because they seem to last so long.

All LSD NiMH batteries are not necessarily the same. Some would claim these are better. We come together here to try to learn the truth of such detailed claims. -69.87.199.6 (talk) 17:54, 25 November 2007 (UTC)[reply] There are no newspaper articles or notable technical articles about Eneloop, and nothing to state why Eneloop is different from other Low-Self-Discharge NiMH batteries. It seems Eneloop is merely a brand-name of Sanyo, and there is nothing notable that sets the technology of Eneloop batteries apart from other LSD-NiMH batteries. --Lester 21:27, 25 November 2007 (UTC)[reply] I agree that this article should be merged into Nickel_metal_hydride_battery#Low_Self_Discharge_Batteries. According to "Charge Retention" paragraph, batteries retain 70% after two years. It should probably be something like 60-70% after two years, but I don't know the accurate numbers.. Mar Garina (talk) 22:07, 28 June 2008 (UTC)[reply] The self discharge of NiMh slows down with time. A LSD type might lose 15% in the first month, but out to two years still have 70% capacity remaining. Sanyo Eneloop AA 2000 mAh LSD batteries have unusually high starting voltage under light load (.5 Amp), 1.48 V (compared to about 1.4 V for most NiMH AA batteries), and unusually high voltage under load, 1.25V at 1A and 1.21V at 2A, mid-discharge. So these would be particularly good for replacing alkaline AA batteries in equipment designed for alkaline: ... The RayOVac Hybrid AA 2100 mAh LSD batteries don't seem to have these unusual high voltages. What about other LSD NiMH batteries? -69.87.199.58 (talk) 16:08, 28 September 2008 (UTC)[reply] In 2007-2008, archae86 tested sets of LSD AA and AAA NiMH, and normal AA NiMH batteries.[4] Self-discharge was measured for up to 3 months. ...the batteries retain 70 to 85% of their capacity after one year when stored at 20 °C (68 °F), 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.
