Question: Is anyone using this to charge a battery larger than 72 amp hours?  If so how is this charger working out for you?
Document: The construction is very robust and waterproof. The design does exactly what is needed to properly charge and maintain a battery. I have two of this model, the first I bought a year ago for one location and the second in November 2013 for a different location. I have a different  version of this unit ( twin 5 amp outputs) that I bought 5 years ago and it is still doing the job correctly.
I purchased this for all outside use. It stayed outside Winter/Summer from 0F to 110F and never missed a lick. charged my trolling motor battery up in just a few hours and maintained that charge even if I didn't use the battery for two months. It has several "stages" of charging and drops amperage to trickle charge level automatically.I strongly recommend the Guest brand marine chargers.
This is a good charger for any single or two battery system. Installed this on a 2006 Ford F-250 Diesel pick-up. This keeps up with the rechargeable flashlights, etc. wired into the battery as well as keeping the battery charge up.
I have had my dump trailer for over six years and never had to change the battery (this runs the dump operation). I screwed up the charger. I ordered the same type of charger and installed the charger and prayed that my battery would take the charge. It took the charge! What a relief! Awsome product!
Amazon service superb as usual. This charger is perfect for my use and the price was very good considering the other choices. I mounted it in my 16' fishing boat to maintain the trolling motor battery for a Minn Kota Terrova 55, which I often run 5 or 6 hours in a day's fishing. No issues in 6 months of use. Should be mounted in a ventilated space - mounted mine vertically on the side under the left console. Seems of good quality and sealed to the elements.
Plug it in and my battery is ready for the lake and river for fishing. Keeps the batteries going in the winter. Only I plug them in once every two months in the winter to keep the batteries fresh. Plug them in everytime coming back from playing to keep them ready for the next trip. Highly recommend if you don't want to lose batteries from not using them enough.
SMALL compact potted electronics easy to install, will probably get a few more for redundancy instead of a very large amp unit
It looks and feels like quality stuff. Easy to install. Works great out of the box and still working great.
This is NOT the 2607A which has two 3 amp outputs and could have been wired for a 24vdc system, or a single 6 amp 12vdc. What you will be shipped is the 2608A which is a single output 12vdc, at 6 amps. I wish the model number listed did not mislead me.
I have had another Guest charger for my trolling motors. Has worked great for years. This 2608 will be used as a make up and occasional winter charger for my main battery. I expect it to last for many years. Had another brand that did not last a year. Value is much more than price.
Answer: yes
