I am running a Trimble R10 base with TDL450 connected via split cable.  My need to run the 35 Watt setting on the TDL all day.  I have heard that some are using deep cycle marine batteries.  What specific brand/model/spec battery are you using with great success?  What charger should I be getting for optimal battery life?

Thanks for your time!

I don't use my 35w radio often -- a TCP connection works most of the time for me -- but when I do I use UHF I power the radio with an Optima D34M battery, and use the Optima charger to charge the battery.

I have been using 55 ah SLA for years.

I add flat connector pig tails. I add 3 of them. One powers the radio, one powers the elec fence, and one (used to) power the Topcon legacy e.

The 55 amp hour sealed lead acid battery is available on eBay, for around $100.00.

The pigtails are heavy, like boats use for their trolling motors. 10 or 12 GA.

To charge, I use a 2 amp trickle charger, that goes into maintenance mode, after batt is charged.

I hope this helps.

Nate

Any deep cycle battery will work fine. We’ve always either purchased
Interstate or CAT batteries; both are
probably overkill but they do fine with GPS & lasers. We’ll keep them handy due to rampant theft
of batteries from equipment &
after some use we simply put them on a battery tender to keep them prepped/ready the occasional usage. not sure why the response was reformatted like this
