sonar batteries

[Papa Sly]

are 12 volt 9 amp batteries all interchangeable for sonar

[Slabseek3r]

Yep. All flasher batteries can be used with all other sonars provided they are the same voltage

Thanks, trying to find the best deal and just wasn't sure.

eBay is a great source.  Usually you can get a 9ah 12v for around $20.

Take a look on amazon last year I got got a pair of 12v 10a for $39.00 free shipping ,

if your thinking about changing the amp hour rating, watch the size differences if your battery has a lowered area to keep it in place. a bigger amp battery probably won't fit that space.

some of us have gone with lithium to install in sonar and some have gone with lithium shuttle. i bought both. here's a deal on the shuttle right now.

The Lithium shuttle is 12aH. You can get a 10aH lithium battery for $100 from FishUSA.

I'm going to try to get a group buy on Dakota Lithium batteries going again. Their 10aH is the same size as a standard 12v sla and should fit in any of your flashers, cameras, etc.

My 10amp sla battery fit both my  lowrance units and both huminbirds , , but they are much heavier , certainly a draw back for many , run time is less as I get 0nly 2 days run , but I do get 5 year life span , I looked at the shuttles and they are very nice
 Guess I’m old and cheap

Fish USA has today only, spend $200, get $40 off.  Could buy 2 Dakota 10ah Lithium batts, get them for $80 each.
Would have to find an item for a few cents to reach the $200 total.

For those of you living in Michigan, Northwoods Wholesale Outlet in Pinconning sells 12v 7ah for $17.00 brand new. Picked one up for my sonar rig.
