need a battery

[mr. t]

need some advice. is the riva battery any good if not what is a good one?

Odysee. That power whatever battery advance auto sells for power sports is a rebranded odysee

Your best bet might be to take your battery out and take it to a local auto parts store. They will be able to match up what you have.

I like the Deka AGM. Me & two other friends all bought Deka batteries over 3 years ago & all 3 are still cranking good.

If you are referring to these AutoCraft AGM batteries, they are made by East-Penn, same product as the well regarded Deka branded factory sealed AGM battery.

Deka AGM batteries can be identified by the terminal post design.



I prefer the Deka AGM battery over the Odyssey brand.

The Odyssey batteries have a vertical threaded post terminal.

ya i had an interstate battery this last one only made it a little over 2 years i need something different thanks for the input everybody!

Here's some interesting info on the Odyssey

The hit or miss on getting an agm that does not sulfate and corrode the terminals is a big gamble. This is performing very well-- more cranking power, no corrosion, much lighter and easier to handle. https://www.amazon.com/Battery-Tende...rds=BTL35A480C

Get a real charger too like a noco

I have had good results with the Deka manufactured ETX factory sealed AGM batteries. Solid terminal design, completely sealed and ready to use from the box. Never seen one corrode around the terminals, good longevity unless stored without a full charge, or allowed to drain down during storage.

Primary downside with Lithium powersports batteries, other than the higher purchase cost, is reduced charge capacity. Only 100 watt hours for the linked product. An ETX16 AGM battery would be rated 19 Amp hours (~228 watt-hours) while ETX30 would be rated 26 Amp-Hours (~360 watt-hours). This translates to potentially less run time with the Lithium battery for a bilge pump, fish finder or sound amplifier when the engine is not running.

The 'Pb equivalent' ratings are imaginary/marketing numbers, not actual capacity. Even the advertised Lithium cranking amp numbers can be marketing speak (marked as LCA in this example), despite the engine starting performance of the better Lithium battery products being quite good.



Sometimes the charging voltage in the watercraft doesn't exactly match with the lithium battery's optimal charge voltage, check the specs for the particular battery and measure the watercraft alternator charging voltage.
