Vex Battery Charging ??

[broken line]

I saw this topic recently but cannot find it. Can I take an old vehicle (12 volt plug end) cell phone charger, cut the end off, replace the ends with those that match the Vex battery and charge the battery by plugging it into the vehicle lighter?

Some cig chargers, such as those for cell phones, are actually less than 12V and are typically 5V at the plug end.

You will run the risk of under or overcharging the battery and damaging the battery, or the sonar unit.

It needs to be a smart charger of the proper amperage and voltage in order to be trustworthy.

The chargers intended for the 7 amp hr batteries charge at 1/2 amp. You'll be well beyond that plugging into the cig lighter. Charging at those higher amps can ruin the battery and become dangerous. In a pinch it will work if you keep it to 5 minute intervals at most.

The old chargers transformer chargers didn't have a shutoff so you had to keep track of charge times and disconnect the charger from the battery. You will be doing the same a volt meter is a must with those old chargers.

As said the cell phone cords are 3.3-5 volts. You'll need to find an adapter from a 12 volt device. Most have the fuse built in but check and of coarse make sure you have the polarity correct. Remember I said this will work in a pinch and should not be even remotely considered as a primary way to charge your battery.

check out strikemaster web site they have a car charger for the eletric auger. the older one were a clamp on style might possibly work good luck Terry

Not a bad plan, that would work as that was a Smart Charger of the proper capacity.

Another option is just use an auto inverter, a economic one will handle the Vexilar 110 to 12V charger just fine.

I agree 100%, get an power inverter and you can use it for flashers, laptops, etc etc etc.

I agree Perchjerker. I have an inverter in the boat and truck for 110.
