Although you can certainly use it just for charging an SLA, one advantage of these types of chargers is they automatically go into float mode to maintain the charge and prolong the life of the battery. This is particularly beneficial for batteries that go fairly long periods of disuse, like motorcycles in the winter, or snow thrower batteries in the summer, etc. I don't doubt that they can put out RFI, but in chasing down RFI at my QTH, which included switching off the power to the entire home, the ones I use (Battery Tender brand) were never identified as causing me any problems. Of course YMMV. On Wednesday, November 24, 2021, 01:36:53 PM MST, Chris <[email protected]> wrote: Hi Jim,
Excellent article. I haven't checked if it is a source of noise, but it doesn't quite matter because this is a charger, not a power supply. I only use it when I need to charge a battery, so it is OK.
