These GP 23A 12 V high-voltage alkaline batteries are exactly what I needed for a few of my small electronics — like the garage-door remote and a couple of key-fobs. They’re compact but deliver a solid 12 V output, making them ideal for low-drain devices that need a consistent voltage.I’ve used one battery in my remote for a few months now, and it’s still going strong. According to the datasheet, it has a nominal capacity of around 55 mAh under a 20 kΩ load. The performance appears stable, and I’ve had no issues with leakage or corrosion, which is a big relief for long-term use.I also appreciate the five-pack: it’s really good value, especially considering how expensive 23A / A23 / MN21 batteries can be individually. The shelf life is solid too — GP advertises up to three years, so I don’t feel stressed about keeping spares around.The only slight drawback is that these aren’t the kind of batteries to use in high-current applications — they’re definitely meant for remote controls, alarms, and similar gadgets. If you tried to run something very power-hungry from them, you’d drain them fast. In fact, people in DIY and electronics forums mention that they can’t drive high-draw devices reliably.Overall, this pack is a solid and trustworthy choice for anyone who needs reliable 12 V batteries for remotes, sensors, or small devices. Recommended if you want quality that lasts without breaking the bank.

Pretty hard batteries to get a hold of in my area in the UK at the minitue took about 10 days in total to arrive but that’s what the delivery date was so came on time pretty cheap compared to other brands so we’ll worth the wait.

GOOD VALUE FOR MONEY AND SEVERS THE REQUIREMENT

Arrived promptly fitted fine but either just not full or not able to handle the current draw for my main bike light word fine in th tail light and secondary front light but 2 straight out of the package into th main light and in 10seconds it dimed and th red battery warning light came on and it set it’s self to minimum power. Tryed a few different ones out the pack same result

Well I purchased these batteries well over a year ago if not longer actually and they are still going strong so that speaks for itself.Use them for my doorbell and they last ages compared to some brands I’ve purchased-even more expensive well known branded names that are dead within months.Usual fast delivery to.In my opinion you can’t go wrong with this brand as they are pure quality-have a really long shelf life to and are superior quality compared to many batteries out there-and also DONT!! Leak to.For the price to they are great-last ages-quality made and outdo many well known brands-and I no this for sure as I’ve tried many before and these beat them hands down.I’ll never buy these overpriced branded batteries again after using this brand put it that way.100% beat any other brand ive used in the past and I’ve used a lot to-well my doorbell is over 7 years old so you can imagine how many times I’ve had to change them-but these out do any other I’ve purchased.The one in at the moment is over a year now-where as a branded one only lasted a few months.Good purchase without a doubt and I highly recommend them from my experience up to date.

Perfect just what I needed good quality

Pretty good price for a pack of 5 MN21 batteries. We had the same battery which came with the remote and lived for more than 4 years and have replaced it with the same brand and power, hope it lives as longer as the last one.
