Son1206S

I have heard on the list that Hawker batteries like at least 6 amps of heavy charging. I've had good luck with Soniel products for making my batteries last longer. I'm looking at a small constant current switching Soniel the Son12065S. 40 bucks. I'd need ten of them. Is the high frequency good enough for my 13ah buddy paired Hawkers? I suspect the Soniel algorythm is what makes them work well. Even at 3 amps a full charge would take about 7 hours. If anyone has a bargain model that works as well I'm all ears. Lawrence Rhodes.

Hawker states their batteries want a minimum of C/3 amps, which for your buddy-paired 13Ah modules (26Ah total) is 7.8A. A 6A Soneil might work, but there is a good chance that it won't. The 1206 you mention is a 3A charger, so there is a very good chance that it will not keep your Hawkers happy.

The 1220SR is a 10A charger and is much more likely to keep your Hawkers happy. However, its efficiency is spec'd as exceeding 80% only when fed 240VAC, and they are not PFC, so you will likely need at least a 20A 120V outlet to run 10 of them at once.

Cheers,

Roger.

Here's a thought. Hit it with a bad boy untill it's up to 80% and then turn on the Soniels. I want something like the Soniels to finish the charge. Lawrence Rhodes.....

I had numerous conversations with the people at Enersys, and their
recommendation was current in the Bulk Phase @ ~ 40% of the 10amp hour
rating.
For this battery it would be ~ 5.2amps.
Looks like your buddy pairs would need ~ 10.5amps.

Thanks;
Dennis
