From: "bcone1381" Vic Syracuse has an article in this months Sport Aviation (June 2020) that deals with Batteries and Alternators. he says not to mistreat a battery by constantly leaving it on a non approved battery tender/charger between flight. Help me understand what an "approved charger" or what to avoid. Specific products will be good. May I assume maybe there are different chargers for different battery types? -------- Brooks Cone Bearhawk Patrol Kit Build Read this topic online here: http://forums.matronics.com/viewtopic.php?p=496836#496836 ________________________________ Message 2 _____________________________________ Time: 09:45:54 AM PST US From: "Robert L.

What Vic is referring to are 'battery maintainers' . . . which may also be a charger but with automatic step-down to a maintenace mode when the battery is topped off. If the advertising literature for the charger includes the word 'maintainer' then it's good to go. Brands like Battery Minder, Battery Tender and Schumacher are several choices to consider. A battery maintainer holds the voltage on a stored battery at JUST ABOVE it's normal resting point. This means that very small, self discharge currents flowing INSIDE the battery will be supported from OUTSIDE instead of from the battery's own resources. It cannot even charge, much less overcharge a battery. Bob . . . ________________________________ Message 3 _____________________________________ Time: 09:46:01 AM PST US From: "Robert L.

Not really . . . there are some so-called, 'smart chargers' with front panel controls suggesting different charging modes for AGM, flooded and GEL batteries . . . but I've never been able to detect any useful differences in their charging protocols. If the battery is suited to run in a vehicle, then any charger suited to charge vehicle batteries is okay. CHARGING is not the critical feature . . . its what the charge does AFTER charging is complete so that overcharging damage does not occur and self-discharge currents are mitigated.
