I'm looking for chargers and came across this one. Anyone have this or have comments? It's over $200 and I want to make sure it does all it claims.CTEK25000

It only goes to 14.4v which is too low for some batteries.It is only a 25 amper which is not enough amps for charging from a generator when running time matters.It's recondition mode says it will restore power by fixing stratification. So the ad writer has no clue what stratification is.You might like the VEC1093DBD depending on what the job is.

BLF13- I saw that 14.4v, but it's the removing sulfating and reconditioning modes I'm interested in. Going to use it when I return home. Goes to 15.7 at 3 amps on reconditioning. here's the manualCTEK 25000 manualThe Black and Decker has been discontinued and has bad reviews, the fan doesn't last.

Others who have other chargers can say better than I can how theirs might do instead. To me the OP one looks expensive and not at all "unique" in what it can do.You can do that job with a 3 amp manual trickle charger if you don't mind keeping an eye on it when the voltage gets high, so it doesn't go over your voltage limit of maybe 16v when desulfating. You have to shut it off yourself when things get too much.There are other automatic chargers that will do that for much less money (Battery Tender?) Also people are using those Meanwell or whatever gizmos that Mex likes for that work.Don't know on the OP one, but "recondition" often means to use pulses for a long time in hopes of crystalizing the sulfate, while "desulfation" or "equalizing" is a different mode where voltage climbs to about 16v and attempts to "overcharge" the battery to bring the sulfate into solution. The pulsing recondition method is somewhat dubious. The high voltage method does work for sure.

i agree BFL on most of what he saidhow ever the pulsing is supposed to be De-crystallizing, aka removing the crystals that form on the plates so they can desolve back into the solutionsome people swear by it, some say its BSMe..i think every little bit helps and it can't hurtequalizing is stirring the electrolyte with high voltagethis removes stratification and also helps desolve any sulfate crystals that come off the platesthe higher voltage is NEEDED to restore electrolyte density ie specific gravitywhich is how the battery gets fully charged to full amp hour capacityi use a B&D 9340 portable charge for this, like many others on here
