There is a battery housing built into it, so you don't need one. I bought a lawn tractor to use with it.

I guess there is. I haven't found the need. Both units went 8 months before needing batteries.

Hi Gordy, I am not sure what is meant by the non-standard battery. The unit runs on the 12V boat battery. I suspect the special battery may be internal to the unit and used to retain data such as your trajectory for prior trips, total elapsed time etc. This actually surprises me in the days of widely available FLASH memory. I purchased a map module...I love it.

No. You'll need to buy another battery for it. Be VERY, VERY careful with the key/latch that's used to lock/unlock the drawer that holds the battery. It is more fragile than it should be and the slightest amount of pressure in opening or locking it will likely break it. If anything were going to be the Achilles's heel of this device - that would be it.

You can buy a power supply to eliminate the need for batteries. Check the instructions or go to google for more information.

This unit MUST be plugged in to operate. Unfortunately it does NOT contain a standalone battery.

No batteries required. Generally, ordinary daylight is quite sufficient. In the nighttime an ordinary electric lamp is enough. It's a great little calculator for a very reasonable price.

Not at all. Leave the batteries in in case you need them. Plug it in when you can.

Yes. I actually have an extra battery that I can keep charged if necessary. You can also purchase an extended battery.

Yes. It is required. I had to purchase it after buying this particular extended battery.

If the AAA battery works, you really don't need this one. However, this NextGen unit is rechargeable, and then it's a question of economy -- and whether you'd also have to buy a recharging device.

Yes , you would need a extended battery cover that you can purchase with the battery.

It doesn't require batteries. It must be plugged into an electrical outlet.

There is no battery required. The connection to the radio is on the inside mount, and the outside is just the antenna mount.

It doesn't need batteries, but you can buy an accessory if you want to use it that way
