Can use 1a charging voltage but need to shorten charging time.. e.g 1 hour only.

QUOTE(Pikichu @ Sep 23 2023, 11:44 AM) Planning to drain, flush, replenish sulfur into battery but first looking for affordable charger. Overcharging the battery can cause battery plates corrosion.. which decreases the battery performance & health.  Swapping acid wont improve your battery conditions. I m in the car battery industry for quite some time.. those battery revitaliser is an overrated scam. If u insist on swapping out the acid, u need to look for sulfuric acid density rating at 1.25sg. Good luck. AbbyCom liked this post

QUOTE(haturaya @ Oct 12 2023, 08:17 PM) Get yourself a bench power supply. Can supply what ever rate that you want. I think TS wants a low output battery charger, yours might be too powderful for TS.. [attachmentid=11481936] Just don't leave it alone as it might damage your battery. I have one, use it to charge many kind of battery.   |

QUOTE(haturaya @ Oct 12 2023, 10:53 PM) I bet u never use one. It's handy as you can dial up / down your voltage & current as you want. yup, my working place chargers are all analog.. except that latest charger which I cant use without my boss supervisions.   |

1 thing I want to point out -
For vehicles lead acid battery, the recommended charging voltage range is 13V(min) - 14.5V(max). |

QUOTE(alexei @ Oct 13 2023, 03:24 PM) does it differ by chemistry? like, calcium, silver, antimony, etc? No idea..My guess - silver is used to boost discharge power but, requires high charging voltages. As for calcium, it's used for reduced electrolytes lost. |
