LIR2032H

While these hold less power compared to their disposable counterpart, you can't change the laws of physics. That's just how batteries work.These last long enough, and they're rechargeable so I don't have to rake around in the cupboard to try and find more when they run flat. They're also pretty affordable in a whole.

Work great .no issues worth the money

Arrived satisfactory and were charged to 80% already. I charged to 100% before use and checked with a meter.I put one in a flickering candle light to see how long it lasted before failing to a point where the light became very low but not completely off. This discharge took about 3 hours. A normal non-rechargeable 2032 can last 3 days in comparison.So, they work okay, but not to be used in continuous discharge applications since they have very low capacity compared to non-rechargeable.Price wise, they are comparable with non-rechargeable types (although it is possible to buy cheap 2032 batteries in certain shops).So really only to be used where usage is low, such as car key fobs.

These batteries have a fairly good 'in-use' time before recharging is required. I might be tempted to buy more later.

These work reall well, I have used them for over a year and they still work.

After some years my keyboard battery died. I got this one as a replacement. Lasted about two hours. Yes, it charges, shows in the battery monitor and all. With the old battery just the light from monitor was enough to keep it going for hours in fully shaded room (solar keyboard, k750). This one charged to 98% lasted me 20 minutes in the game before it died. Total waste of material it is made of. Unusable

Very quick to change to full even on standard USB output from computer at my cnc machine at work. Would reckon about two hours maybe a little more. Careful how you insert them into charger as they are in different directions for insertion opposite each other. Hopefully they will pay for themselves over the years, don't see the point of throwing batteries away and having to pay out all over again. I've many other batteries that have lasted for years and paid for themselves easily.

Just learned that all rechargable button batteries have on 20% of the charge of a non-rechargable battery.They don't last very long between recharges.A wrong purchase.
