:looking to buy new batteries for my 25' Cat w/ 565 blower mtr. Are the Optima blue top batteries worth the money or just go with some new deep cycle Interstate batteries ??

Griff

I would get one Interstate Marine regular starting battery and one starting/deep cycle battery.

optima,,junk stick with interstate..i have 2 27 series and they lasted over 10 yrs..they wing my engine over with ease..

Agreed. Never had any luck with optimas. Only lasted a year and half on each set I've ever had!

I have Optimas and would recommend going to the Interstates.

Interstates in my boat are going on their 8th season as long as they load test OK.

Interstate deep cycle and an onboard charger plugged in each night.

Its better to have more battery capacity and not run them down as far.
Don't run them down past mid 11v, keep them charged all winter, battery will last a long time.

If you do the math, it's really hard to justify the cost of an Optima even if you are replacing a couple normal deep cycles. Get a good deep cycle with a warranty and you should be good to go!

You can't beat the AGM (absorbed glass matt) batteries, whatever the brand. I switched after breaking two separate Exide 1000CCA cranking batteries from wake hopping.

The AGM's are tough as a brick, don't self discharge and work in any position. I've had the same two Seavolt AGM's from West Marine for 5 years now.
