I have used two different units of the Battery Tender 6A charger model. One failed (after many years) leading to overvoltage. The other generates huge amounts of RFI especially on 20m. They certainly seem smostly ok, with those caveats.
I recently got an Optimate 3+, which is only 600 mA but claims to do desulphating. Notably, when going into float mode, it float charges for 30m and then lets the battery sit for 30m, which seems nicer to the battery, and also lets it detect more cases of batteries that are not ok. RFI-wise it seems not as bad but hardly ok. I also have a gensun gv-5 MPPT solar controller. It and a panel makes an RFI-quiet charger, at least on some days. It floats at 13.5V, nd does equalization at 14.2ish once every 7 days. 73 de n1dam ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
