Hello,

I would like to get a battery that is fairly easily transported to use for portable expeditions.  I am looking for something that has a handle, comes with a charger, DC power (cigarette lighter) jack and hopefully 7-8 Ah or higher.  I have bought a couple of these in the past with not so great results.  Don't seem to last long

Wonder what brands/models are out there now that people here might suggest.

Thanks & 73

Russ,
I'd like to hear some "veteran" 817 users input on this as well.  I just got my 817 last week and absoultely adore this rig.  I have been running it off of 8 2500mAh AA batteries...it works, but I, too, would like to have a power solution that I could haul with me and have greater capacity.  I know the Power Port Store makes several options that would foot the bill, but they seem a little pricey (just my opinion).

73!

I've been using a 17 Ah automotive jump start battery that I bought at WalMart.  It came with a wall-wart trickle charger for under 80 bucks.  In the field, I keep it charged with a Unisolar 32 W solar array and a small Morningstar charge regulator.  There's enough daylight in the summer to keep the rig running 24/7.  Works great for Field Day.

If you're going to use a jump start battery, buy it from a store such as WalMart or Sears.  They turn their inventories often enough that you shouldn't have to worry about getting a battery that's been sitting uncharged for months on the store shelf.

Please check out the Nomad 300 portable power pack
from www.solarsense.com . I've been using one for
several years with my Yaesu FT-290RII.

The best battery would be one that is of the correct voltage and preferrably charged up. Light enough to carry might be a good trait too!

9V is better than 12V for the FT-817 as it has an internal regulator to cut the voltage down anyway.

Try one of the 9v LiFeSO4 packs from Batteryspace.

I have a 12 volt gel cell with 5 amps. It gets me about 4 hours of transmitting 5 watts on SSB and 6 hours of standby. The battery is light and fits in my grab bag with radio and portable antenna.

If your not too worried about weaight check out the Xantrex XPower 400R.  http://www.xantrex.com/web/id/177/p/1/pt/30/product.asp

I have one of these and use it frequently with both my 2m/70cm rig and my K2 qrp.  It has a Built-in 400 watt inverter and a Sealed, non-spillable 20 amp-hour AGM battery.  I find it to be quite handy even if it is a bit heavy.  I wouldn't want to take it backpacking but for car camping and genral portable use it is great.
