Questions & Answers for BatteryMINDer Battery Charger / Maintainer with Desulphator - 12 Volt 2/4/8 Amp, Model# 12248

Question

Proper Equipment Use and Installation

This charger would be bought for a standby generator for a rural water service district.
Would this equipment be suitable to remain engaged to the battery / charging system while the generator engine is running for an extended period of time? Or should it be disconnected after startup?
Also, based on information from the owners manual, would it be OK to mount the charger inside the vented housing of the generator set. That being from the concern of gases emitted from the battery and ruining the charger and effects on the charger from the heat of being in an enclosed although vented space.
Thanks

This maintainer would be a good choice to keep the battery maintained in your generator. The leads from the BatteryMinder should be disconnected before starting the generator. I would recommend mounting this item on the outside of the enclosure so that it doesn't get too close to any heat that would be strong enough to melt or degrade the housing. The housing is water tight so weather should not be a concern.

I would leave it hooked to the battery but away from heat and battery fumes. It can be used on board a car or truck-hooked up- but away from engine heat. Probably best to unhook it after charging and maintaining the battery.

The BatteryMINDer can be safely left connected at all times.

You should try to keep operational temperatures below 40C / 104F, they should never exceed 50C 125F.

The BatteryMINDer itself it designed to never cause outgassing on a healthy battery. I am assuming the gassing you are talking about is due to the generator connection. Always take every precaution when dealing with gasses emitted from a battery as they are explosive. All electrical connections need to be secure and insulated to remove any chance of sparking (not just those to the BatteryMINDer). In addition the BatteryMINDer and all other electronics should be mounted as far away (upwind) as possible. Although the BatteryMINDer is sealed with a rubber grommet, it is always best to err on the side of caution.

Question

Does the battery need to be disconnected during desulphation?

I understand that the desulphation phase for the 12248 applies short duration, high voltage pulses to the battery. I'm concerned that if it remains connected to an automobile's electronics that they could be damaged - ECM, alarm, radio stand-by, remote entry electronics, etc.

Is it safe to connect it to the auto battery while it is in the vehicle and connected?

Are there any equipment damage warranties?

The Battery Minder does not need to be disconnected during desulphation. The unit needs to be plugged into a 110 volt power source at all times during operation. The unit will not damage any of the automobile's electronics. The unit will perform as intended as long as the battery is in good working order. There are not equipment damage warranties available for this item.

It is perfectly safe to connect to your battery while in the vehicle. We do not have an equipment damage warranty (we have a 5 year manufactures warranty), but we have never had any issues.

Car alternators put out much higher voltages and dirtier power then a BatteryMINDer. As such the equipment in your car is built with much higher voltage tolerances then a BatteryMINDer will ever put out.

Yes. I have used this product for over five years and it works just as well right in the vehicle while the battery is hooked up to the vehicle. Make sure you disconnect it before starting as a precaution.

The model #12248 BatterMINDer comes with one battery clip set and one ring terminal set (depending if the intention is a permanent or temporary mount). Additional battery cables would have to made up of 18 gauge insulated wire.

To use this item with 6 volt batteries would require that two 6 volt batteries be wired in series. When used in this manner the batteries would need to be fully charged prior connecting the BatteryMINDer. This type of use would be for maintaining fully charged batteries only and should not be used to charge.

Only if you put 2 6Volt batteries in series, this is a 12Volt charger only. I have used this charger on 6 volt golf cart batteries two at a time with sucess.

The desulfating ability between the two is the same. The difference is the #167988 (Model #12248) can produce both more amps and can charge more batteries at a single time.

This BatteryMINDer Battery Charger charges at multiple amps depending on the voltage in the battery. It does not shut off. It will always provide some current, but will not overcharge. This battery charger is not designed to load test a battery.
