Charging gelcells?
Anyone using gells for their second battery? I was given a couple of nice MK 12 volt gelcells. On the battery it says specifically; "charge voltage not to exceed 14.1 volts". I believe the altenator puts out more than that. Research has shown me that this is common among gells, but I didn't really find any answers for vehicle applications other than expensive voltage regulators. Any suggestions?

Re: Charging gelcells?
On that brochure link you posted it says charge voltage cycle: 13.8-14.6 and float charge: 13.4-13.6
My alternator outputs 14.5 as I believe most factory alternators do (at least the ones I've messed with). So it should be good.
But then again, I'm starting a battery bank of lawn mower batteries .

Re: Charging gelcells?
Thanks. Ya, I'm wondering why the battery label says 14.1 and the specs say 13.8-14.6? My old analog multimeter isn't accurate enough to get a good voltage output on my alternator. May be time to upgrade to digital.
