If you did manage to reverse the battery polarity, it would in most cases spell doom for the battery. In order to reverse the charge on a battery, it has to be 100% discharged first. To try to save the battery, it would have to have a second 100% discharge. There would not be much hope of recovery.

Suitable for all types of lead-acid batteries. Battery Charging Stage:5-steps automatic charging cycle. Intuitive 3 Safety Protection:Reverse polarity/Over heat

and shipping upgrades are available as well. by the battery edge, otherwise you will harm the trolleys electronics by reversed polarity.

A lead acid battery typically will be fully charged at rest at 12.6-12.8V where as a LiFePO4 battery will be 13.3-13.4V. A lead acid battery. LiFePO4 batteries operate in a very narrow voltage range with only 0.5V from full all the way down to 20% state of charge. Even at 25% state of charge it will still be at approx 12.8V whereas a lead acid 2016-06-01 “Lead acid batteries should be discharged only by 50% to increase its life” – is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid battery … As far as I know, the optimal charge current rate for lead-acid battery is in between 10-30% of its nominal capacity. (2,5Ah -> 0,25-0,75A)The higher the charge current, the higher the degradation Partial State of Charge (PSOC) in Lead-acid batteries and sulphation The problem It is important for lead-acid batteries to be maintained fully charged.

Suitable for 12/24V Normal Lead Acid, Sealed, Gel and 12V Lipo4 Batteries This unit offers reverse-polarity protection under charging modes, the RED LED

seems like a quality product with the usual loads of crap marketing BS thrown in. The water may not matter much. If your battery is not old and I don’t know enough to say what is old for various lead acid battery types, your battery may be sulfated.

Conclusion. There you have it.

However, Battery Sulfation can be reversed. This video prov 2009-04-28 Circuits for Lead Acid Battery Charging from a Solar Panel with Maximum Peak Power Tracking (MPPT) Introduction The following paper describes in detail the principle operation of the NCP1294, switching controller, and associated circuits for lead acid battery charging with MPPT. A design example and test data are included. Lead-acid battery charge in 12-16 hours (10 hours with multi-stage methods, 36 hours for larger capacity batteries) Charging voltage is critical and range from 2.30-2.45 volts per cell.

Partial State of Charge (PSOC) in Lead-acid batteries and sulphation The problem It is important for lead-acid batteries to be maintained fully charged. During discharge, small crystals of lead sulfate are created on the battery plates and are dissolved again during recharge. Leaving the battery uncharged, the crystals gradually re-crystalize to larger ones, difficult to

2. This charger is only suitable for normal lead acid, sealed, leisure or gel batteries and should not be used to recharge.

Do remember that battery voltage readings are temperature dependent. So between 50F and 80F could have a 10% difference in charge state. For really serious work advisable to take temperature of the battery acid for standard lead acid batteries. Secondly pulling voltage down to less than 50% remaining capacity permanently devalues the battery.

Lead-Acid Batteries Constantine Spanos,a,b, vances in utilizing inverse charge techniques were made in 2009.8,11 to positive electrode grid corrosion by allowing for battery use in a reversed polarity state after a deﬁned period of time.12 None of these 2008-07-25 2020-07-15 2014-08-19 This condition can be exacerbated with smaller lead acid batteries, such as motorcycle batteries.
