Charge setting for AGM Battery (1 Viewer)

[1948]

JUst bought AGM batteries to replace gel batteries, the electroblok charge setting is in gel position at present
Can anyone advise whether I need to move the charge setting to wet for the new AGM batteries. or leave the setting at gel position.
Thanks in advance

i think its a wet battery but have a look at this first.. Broken Link Removed

AGMs are just a variant of the SLA, so I would say change it. Gels need a higher initial charge voltage that can damage the plates in a lead acid

Quote below from a battery forum... hope it helps


A fully charged 12 volt AGM battery's voltage should read about 12.7 volts. You should charge it with about 1 - 2 amps of charge current at charge voltage 14.2 - 14.4 Vdc then drop the current to a trickle and float the voltage at about 13.4 after full charge.
here is a nice charger in your price range, if you do a search you may find a better deal, but Northern is a well known company and from the description this charger will address all your concerns.
.

I would not use a charger that does not have current limiting, i.e. a normal flooded-cell car battery charger or any other method without limiting current. connect + to + and - to -.

Just raed the article a bit confused says AGM works like lead acid batteries but then says it can be discharged to 50% compare with LA battery 80% Then go on to say charging method important. Should it be charged like LA or otherwise. No wiser, gel or wet setting ??

was told that in gel setting my charge will be 14.3v for 8 hours then floating charge 13,7v at wet setting charge 14.3v for one hour then 13.7v after My problem is which setting my new AGM battery applies

sorryoh: not trying to confuse this may also help .. about 3 paras from bottom may help.:thumb: http://www.optimabatteries.com/product_support/charging_agmbattery.php

seems there may be 3 settings needed on a charger , wet / Gel / AGM i was trying to learn while "trying to help out"" oh:oh: sorry

Thanks Phill
A bit clearer now My hymer electrobolk only got 2 charging setting so looks like it will be on wet setting from now on

mine only has Gel and Wet also but on balance it looks athough wet is the closest setting to avoid undercharging the AGM.. good luck:thumb:

an AGM (absorbed glass mat) is a wet battery but the electrolyte is suspended in the glass mat rather than a free running liquid.
