Good battery for my equipment works amazing one goes low i just charge it and continue

Everyone wants to pay a little less and, let's say, "cheat fate" a bit. Plus, let’s remember the environment! To reduce battery waste, what do we need to do? We need to recharge them. Of course, regular batteries aren’t rechargeable, and this brings us to the product in our review. Even though these batteries might seem like a great buy, don’t get too excited just yet. The thing is, they have a very low capacity of only 200 mAh. This isn’t exactly a flaw but rather a feature of these batteries, and if you’re buying them, you need to be clear on what they’re meant for. In simple terms, these batteries aren’t suitable for high-power devices like walkie-talkies, microphones, or guitar pedals. But for smoke detectors, they’re ideal, as these devices don’t require much power. I’ve tried these batteries, and they've been working in my home smoke detector for several months without needing a recharge. Plus, while one battery is in the smoke detector, the other can be charged. The manufacturer claims they can withstand up to 1,000 recharge cycles, though it's unlikely that you’ll ever need that many in practice. In the end, we’re looking at nearly everlasting batteries for about the same price as two from a popular brand. Not bad, right? Just remember what I mentioned earlier, and don’t forget the charger.

Gran calidad, recargables, me encanta el contenedor plástico, funcionan correctamente, muy buena compra.

Works great with co detector that requires a true 9v battery

good

Great for the money

Works good.

These are real 9 vdc rechargeable batteries--but that means they will run low power devices like smoke alarms, but if you need the regular 8.5vdc rechargeables with power (but can't be used in smoke alarms), then don't buy these. The product is good and labeled correctly, but no good for what I needed. I guess these are for smoke alarms and other low power devices. 200 mAh's is almost nothing.

charge dont hold a day what a waste
