Smart Car Battery Charger

[dr. d]

Just pulling your leg doc.



Pretty sure the venting happened before charging since this was the first time the batteries were hooked up to the charger. The batteries already had residue on them when I first popped the hood.

Just wondering. Has any battery failed you despite maintenance during the warranty period?

heh heh.

once, i was able to get a new battery, because my old battery failed one month before the warranty lapsed. "i was so happy."
there was nothing to maintain, as it was one of those "maintenance-free" batteries.
there was nothing wrong with my charging system. it was plain battery failure.

on three occasions that i can remember,
my battery failed because my alternator failed and couldn't charge the battery.
when the alternator got fixed, the battery re-gained its composure.

in our experience,
the white residue around our battery terminal was traced to a crack in the battery's cell. obviously, someone did it wrong, when it did/undid the battery cable.

Just bought an Elevo Battery Charger at a Concorde Shop in SM.

I found in the manual that says:

1.) Attach a 24-inch length #6AWG insulated battery cable to the negative battery post
2.) Connect the positive clamp to positive post.
3.) Connect the negative clamp to the to the free end of this #6AWG battery cable connected to the negative battery terminal.


Can I not just connect the negative clamp DIRECTLY to the negative battery post, like no more need for that #6AWG wire?

But most locally available "maintenance free" batteries aren't really MF. If you can pop the top covers off, it's not maintenance free. Motolite conveniently hides the ports with that "Do not remove sticker". "SMF" means semi-maintenance free.

i connect directly.
i do not remember the safety issue involved.

i am not about to theorize on what the corporation was thinking, when they designed their battery.
but i am concerned about the possible loss of warranty if i tear at the warning sticker, and the battery dies within the warranty period. sayang rin naman ang libreng bagong replacement battery...

personally, i suspect that were i to open the filler holes of these so-called MF batteries and inspect the electrolyte levels halfway down the warranty period, the battery will have low water levels that will necessitate adding water.
i believe that if i were to add water, my battery will still be alive even after the warranty period.
but these are my thoughts only.

heh heh.

there's also LM, "low maintancance".

Just received my ordered FOXSUR 7stage Smart Battery Charger...Looks decent including its box and all inclusive connectors. From the looks of it it is a direct cloned ng CTEK, though a lot bigger in dimension si Foxsur. Tested it for 2days in a row to 2 of my cars and it seems working as it should, the charger gets a bit warm but no worries daw as it has its own Thermal proctect, currently nakaFloat charge sya sa Everest ko now.

My only gripe is the AC electrical cord is too short, had to get an extension cable pa.. Hoping matibay and serves for many years..

the final test of these intelligent chargers, is the increased lifespan of the batteries.
this should be evident in the far future.
pray you remember to feed us.

splice up the short cord, with an adequately long cord. para hindi na hassle ang extension cord.

I see... I thought LM means Little Missy. [emoji3]

Is she still here and active?

LM.
Little Missy.
Low maintenance.
is there something i am not connecting?

apologies to LM.
couldn't resist.
kasalanan ni arch, for bringing it up.

Looks like it is really true na kapag mostly nakapark lang and long duration i.e. 2weeks not Run ang Car the battery degrades. I have this Lancol Battery Tester and just before the lockdown manage to get a data..Battery Health =92% Internal R = 4.50mOhm (March12) Today the reading are: Battery Health =87% and Internal R = 4.65mOhm. Both were tested *98% charge state of my 6month Old Amaron Battery. When this battery was installed also took a baseline reading using same Batt. Tester and Health *100% and Battery internal R =4.23mOhm.

Will observe in a month time if meron degradation pa. It seems my defective blendor motor is really draining my battery.

Bought another charger... lol this is quickly becoming an obsession. No BT this time, so I'm using an IP camera to monitor remotely.

No need to remove the car terminals from the battery while charging?

Ideally, yes. Some automatic chargers might not stop charging when the parasitic load is interfering with its measurements. But for practical reasons, no need if you're just topping it off.

I don't trust this charger enough to leave it on indefinitely. I got into this with my eyes wide open.... I know it's not a CTEK, so I won't expect it to behave as such.

i don't, when charging using my dumb, basic charger.
just don't crank the engine.

Thanks OJ and Doc [emoji106]

While parked waiting at Meralco compound i decided to check the charging voltage of my gs. 14.1V lang with engine on idle. Mababa di ba? Dapat at least 14.5V? napa-order tuloy ako ng smart battery charger sa lazada, yung Foxsur na100 amp model. Di ko nakita agad yung 150 amp e yun sana pero for shipping na kasi nung makita ko. Anyway good naman na for 3sm yung 100 amp. Di pa dumadating. Sana oem.

[12vdc]

13.8V is the float-charge for 12V system

4.2V for 3.6V system

42V for 36V

55.2V for 48V...
