José R.: Es una excelente compra, aquí conseguía otras baterías casi al mismo precio y solo 2 y me duraban 3 meses y eso que eran recargables, estas pilas eran 4 y duran mucho.

stephen caldwell: I read the title a rechargable but it does not have a charge port and when I put it into my new battery charger, it never completes the charge cycle.

Joseph M Braddock: Our model railroad club uses these in Digitrax duplex throttles and they work great. Our last batch purchased lasted at least five years. We meet weekly and have public operating sessions monthly with 12 to 14 operators. The batteries easily last through the operating session with power to spare. I'd highly recommend.

Derek Sisson: I've been using rechargeable batteries for the last 5 years and these are head and shoulders above what I thought were the best after doing my due diligence in researching "the best". I recharge all of the batteries (total of 34 9V batteries) in use every year between Christmas and New Years, and track in an excel sheet the pre/post charge voltages. These are the best, as compared to the EBL and Maximal Power 9V's I'm also using.

CWOBOSN4: I own a lot of NiMH batteries ... mostly AAs & AAAs, but I do have a fair amount of C, D and 9V.

Before I give my review, let me state the importance of having a good quality Battery Charger. I typically use a Tenergy T9688 Battery Charger & I have an identical C. Crane-branded model as the T9688. If you don't have a decent charger, you won't get satisfactory performance from ANY NiMH battery! Choose a charger that (1) Reconditions batteries; and (2) Can identify batteries with bad cells that need to be discarded (recycled).

I have found these Tenergy LSD Low Self Discharge 200 mAh 9-Volt batteries and the [regular] Tenergy 250 mAh 9V to be the best 9V NiMH batteries that I have used. Both retain a charge for a long time - especially these LSDs. As an example I've switched over all 7 of my home's smoke detectors with a mixture of both and I've found them to be reliable and durable - nearly the same life (before needing a re-charge] as throw-away Duracells. I would not use these in something as important as smoke detectors if I did not have complete faith in their performance! And since they are Green/re-chargeable, you save money within a short period of time...

Wayne: I have a clock radio that uses a 9v battery for backup in case of power failures. When the power goes out the clock display shuts off to save power but the battery allows it to still keep time and if your alarm is set it will go off as usual. The clock has a low-battery warning light to let you know when to replace (or in my case recharge) the battery.

I was using one of the first old style NiMH 9v batteries that was not low self-discharge that had a 150mah capacity and I think around 7.2v output. When it was fully charged and I put it into the clock radio it would take literally 3 or 4 seconds for the low battery light to come on. Obviously the battery didn't have a voltage above the threshold of the warning light so it came on immediately and stayed on. The battery did have enough power to run the clock if we lost power which was good, but it was annoying that I didn't have any way to know when the battery was drained. I found out through trial and error that the battery would only last about two or three months due to it self-discharging over that time. And that was without any power outages.

So I went with this new low self-discharge 9V battery to see what would...
