When it comes to those less-expensive chinese chargers with funny-sounding names, this one from Aimtom was the best I could find, in terms of features and price. I think that in general, charging of a lead-acid battery is well-understood, so I don’t doubt that the algorithms are good.
I don’t know whether the way they are programmed makes any difference, as I could not find any reviews that scrutinized their charge algorithms. Chargers are expensive, because of the high-current transistors and capacitors inside, but also ‘features’. I think it’s worth a shot if you can get a decent charger for $35 instead of $90. I found lots of expensive and inexpensive chargers on Amazon, but which one to choose? I think that a good brand will produce a better quality charger, but then there are these generic-brand Chinese ones, where quality is variable. And as for 4-stage or 7 or 9-stage, I don’t think it matters too much, so I would not be swayed by the number of stages offered in a charger. While these computerized battery-charging features never existed in the old days, they are standard today, and absolutely required if you want to charge a battery with the least amount of degradation or damage. Then, they have the 7-stage or even 9-stage chargers, depending on what you might call a ‘stage’ – that add a few extra steps that are not strictly required, but might help to preserve battery life, or at least charge it up with the least amount of degradation usually associated with a charge-cycle.Īll of this is made possible with an embedded microprocessor, which is programmed to use different charge parameters at each stage, using different voltages, fixed or variable current, and adjust these parameters dynamically, according to how the charging progresses.

This will extend the battery’s life, and might even bring a dead battery back from the dead, although never with full 100% capacity. Desulfation will use a higher-than-normal voltage in short bursts, to force Lead Sulfate into solution, removing this build-up which interferes with a battery’s performance. During my research I learned that these multi-stage ‘smart’ chargers exist, and they can not only charge any battery, but they do it better in so many ways.Ī basic charger is 3-stage (bulk, absorption, float) and a 4-stage adds desulfation. I found that charging at a slow 1.5A should not harm a battery, even if deeply discharged, so I’m still confused why they recommended against it. I searched the web to better understand why this might be.
When I looked at the user guide, it says you should not use it to charge larger (car) batteries, and if you do, it might reduce its capacity. I have a Schumacher 1.5A trickle charger, which i’ve used to charge and maintain various batteries.
Has auto-memory, which returns to last selected mode when restarted, and also automatically adjusts itself to changing current needs. 24/7 BATTERY MAINTAINER: Designed to bring a battery back up to a full state of charge and then maintain a battery at 100% indefinitely without the worry of typical trickle chargers that overcharge and burn up batteries.SMART CHARGING MODE: Equipped with a 1A slow charge mode and a 4A fast charge mode, the intelligent 8-stage charging process allows for optimally complete battery charging without fear of overcharging.Automatically detectssulfated batteries and attempts to repair them if possible. SIMPLE AND PRACTICAL TO USE: Using a backlit LCD display, the IBC-4000 charger clearly and visibly shows charging voltage, current, battery type, charging mode, and the percentage of power remaining.It is also IP65 waterproof and has a snow mode for low temperature operation. TOTAL PROTECTION: Offers safety protection against reverse-polarity, over-current, overload, over-voltage, over-charge, and over-temperature.
Automatically detects battery type and voltage needed. HIGHLY COMPATIBLE: Suitable for both 6V and 12V batteries: SLA, WET, MF, FLOODED, GEL, VRLA, AGM, EFB, LIFEPO4 and LITHIUM-ION batteries, widely used in cars, motorcycles, boats, ATVs, mowers, snowmobiles, and others.
