Leisure battery numpty

[Dave79]

I have a 10" Meade lxd75, a Kendrick digifire 7 & a travel hair dryer (coz the corrector plate's a pain in the bum for dew. Honest!)

If I get a leisure battery, will I need an inverter?

All that lot will work on 12 volts DC, but not too sure about your hair dryer anyway it's best not to be using 240V in damp conditions you can get 12 volt hair dryers for £10 - £12, so no invererted needed

You can run all that on 12v, including a hair dryer made for 12v.

But be aware the hair dryer will use a lot of current, but as you will only use it for short time you should be ok.

Cheers guys.

The hair dryer is 12v, I didn't fancy even attempting to remove dew with 240v, risking electrocution or even worse, cracking the corrector plate coz it got too hot, too quickly. Lol.

Thanks again ;-)

Inverters are not all that efficient - much better, as said, to use everything 12v. To guesstimate the capacity of leisure battery needed add up all the Amps you will be drawing eg 2A for the mount, 4A for eg a camera = 6A. Double the answer = 12A. This gives a figure for amps per hour. If you use your kit for, say, 6 hours then you need 12 x 6 = 72 Ah (Amp-Hours) capacity.

The "double it" bit in the calculation is to allow for the fact that you should not really run a battery below 50% capacity or you will start to shorten its life. Don't forget to account for a decent charger/conditioner when you cost out your purchase - these can cost almost as much as the battery but are definately worth every penny as they will keep your battery in exellent condition for years.
