Hi,
Any idea in getting '12v 300Ma' or 0.3a charger ?

Have a lead acid battery that requires this charging specification.
Tried 1a charger which dries out battery, added distilled water 2x.
Yuasa charger would cost over RM200+ which is too costly.



Any suggestions are welcomed.

+1 Thank you for introducing this device.

Did 6V 10A but battery would not charge up to its capability and required state.

Even tried 30 minutes to prevent over heating and 2 hours because 1 hour did not charge up (as above)

+1 Appreciate you share your experience. Unable to trickle charge & auto stop.

Anyone would like to recommend supplier for Imax B6 charger, feel free to PM me. I will be shopping for one. I seen ecommerce offer them, but I prefer to support your supplier to thank you for sharing your thoughts.

Planning to drain, flush, replenish sulfur into battery but first looking for affordable charger.

Thank you for sharing your experience.
The method of dealing with battery that you used, is it listed online or youtube? Can share the links?
Much appreciated.

Thank you.
I don't know what I am doing.

+1 Thank you for sharing your experience. I shall avoid revitaliser.
I am looking for sulfuric from retail supplier, after investing in charger.

I searched to trade in this battery but no one wants. So left to dump it or recondition it.

The battery failed, then left unattended for long time.
Recently charged it, it boiled, added distilled, now looking for 0.3A charger.
Then likely looking for sulfuric acid from retail supplier.

No. This is a side project while Lazada wasting my time.

Thank you for sharing in the other comment.
They look cool but cost a lot.

For 200 budget, maybe get a SMR (small modular reactor) instead.
Then more research required.

Now that you asked I do not remember. I did recall seeing previous charge went beyond 10v.

GS GTZ4V 12V 3Ah (10hr)

Bought a new one, cost over RM120, if memory serves.
The second one did not last as long as GS.
Third one cost over RM210, if I recall. This one is lasting.
Instruction is to add distilled after 15 months but no indication of volume.

I dont know if recond is cheaper or not.

Eventually, the battery needs to be recharge or landfill.
LYN lots of 20k salary would not waste time or care about eco.
But for the few who comment and guide me - Thank you.

Probably IMAX B6 charger, from Cindy's in Kepong, about RM80+
Then a clamp meter from Mr.DIY RM32
Bought Aneng ST180 at 26, claim manufac warranty, but Lazada refuse to refund.
Now learning to use PGmall and Mudah.my

Still searching for sulphur. Its a side project and can only look into this when time permits.

+1 Thank you for this recommendation.
A bench power unit is costly.

+1 Thank you. I notice lead acid battery can apply different charging techniques.
Such as pulse charging, high amp charge and trickle charge. I was looking to trickle charge.

+1 Thanks for sharing.


In the end, I opt for an IMAX B6 v2 charger.
I could not find battery acid at reasonable price.
I abandon the project, salvage acid into another battery.

The bench charger was the best tool but the cost exceed a new battery.
Now that battery is dried out useless.

Thank you all for your input and thoughts.

Thank you
I browse cannot find how the charger enables setting between the 3 modes.
The promo price is 162 exclude shipping, very costly to getting it wrong.

Thanks.
I google "charger 5A1A" but no clear result.

Thank you.
