Will this charger work with Optima batteries?

I would think so, but I'd recommend you check with the battery manufacturer to confirm it can be charged by a conventional charger.

No, not in my opinion. This unit will recondition and charge a very low AGM battery while most charger won't. Optima also offers a smaller trickle unit that will insure your AGM stays healthy assuming your AGM is in a vehicle that sits more than it's driven - or boat...

Optima and nearly all mfr's. of AGM batteries like these recommend a three stage, digital, charger. Stage 1 is a bulk delivery, at peak voltage, Stage 2 is a tapering charge; still at higher voltage but not continuous delivery, and Stage 3 is more of a maintenance mode where the charger only delivers capacity to the battery if it needs it, while maintaining the standing voltage at around 13.5VDC. I have my pair connected to a Digital MinnKota 210C(two 5A banks), and I use a Schumacher 15A single bank ship and shore marine model charger I purchased on the web as a backup. Both work exceptionally well with the Optima's, do not overcharge them, and keep the standing voltage where it needs to be.

I have used several chargers and they have all worked with these batteries. You should not have to purchase a specific one.

The description of the charger says it will work for the 18650 batteries, as long as it does not have the protection board. However, it also specifies the 3.7 volt 2600 mAh batteries. I used it on an off brand 18650 battery that was a 3.7 v. 2600mAh and it charged them fine . I don't know if a 3.6 v 2900mAh battery will work, for sure, but think it should.

Standard battery tenders are not designed to work with hi-performance AGM-type batteries. The Optima charger allows you to select which type of battery you are charging.

This charger is only for Shorai battieries. It comes only with a Shorai connector. For other batteries you can read about the Battery Tender Green Lithium Junior 002-0198LI

I really don't know. That would be a question for the manufacturer. I see no reason that it would not work with the proper setup, charger and battery type.

I am not using it on AGM batteries, but they are just lead acid batteries in a more efficient configuration, so I wouldn't be afraid to use this battery charger on AGM batteries.

david costa - makita chargers work just fine for this battery. i don't know what "tooldawg" thinks is an "optimal charge" but when i charge these batteries on my makita charger they operate stronger and at least 1.25x longer than makita's biggest 18v batteries. i've been using mine for over a year with no problems.

A couple of things to know about these type of batteries. One never let them sit for long periods of allowing them to discharge below 10.5 volts. They will not recover. I have a battery tender in my boat which regulates these batteries at full charge at all times. Second your charger should have a AGM setting. You can find what you need on optima's web site. http://www.optimabatteries.com

Optima is fine with CTEK but six batteries will probably take very long time for 5A but will work. I use OPTIMA on my truck and Jeep and works great

This charger is designed for AGM batteries. Works very well with the agm battery in my Harley, and the diehard in my truck.

Forest, I I don't know. I have 4 18volt Haticha batteries, but 2 different series. This charger only partially charges. I mean it lasts for about 3 minutes. I think we mave bee duped.

I just looked up the specs on this charger and it says it works on the battery your asking about. Just scroll down and look at the chart :)

yes it will work great on it just follow the instructions on what batteries you have and you should be good I use these chargers all the time when it coast to much for me to fix the OEM charger

Yes, I charge mine with this charger, only takes a couple of hours per battery.
