Battery opinions

Trojan is tough to beat for quality.

I looked extensively and cost the T-145's to the T125's. Local dealer who owned DP talked me into going to the T-145's replacing my four dead OEM brand that were apparently in poor shape when I bought my 2016 Fleetwood. I have the residential Samsung RF-18 fridge and at the end had a tough time going overnight in cool weather.

I really struggled making the decision as I had two T-125's in my old MH and they served me well. Bottom line was I went and bought four Costco/Interstate last month and will add another two or four, depending on the bank account, this month. I just couldn't justify the cost of Trojan over the long run. DW makes donations at the local casino's and we will spend 2/3 nights at one near our daughter.

From everything I have read, everyone says go with the T-125's over the T-145's as they are the best bank for the buck and my feeble mind I figured the same.

What ever you do add a watering system to it. Makes care so much easier. I got a Flow-Rite on Amazon you can gang them together to water how ever many batteries you have.

I have Trojan T-125s now, they've been in service 4 years. and they won't hold a charge very long. we were getting 5 days on batteries but now we can only go 2 before we get the low battery light.

Are you going to go to AGM batteries?

I recently replaced my flooded cell GC6 batteries with AGM, tired of checking the water all the time.

I’m happy with my T125s. Probably try T1275s next time.

Most deep cycle batteries will last about 5 years. AGM are great but wet cell can last longer if properly maintained. After a full discharge, they must be equalized (A higher per cell voltage than a normal charge) Also, every time a battery has been discharged, it does lose some of its capacity. Temperature also plays into this as well. Optimal battery performance is 77 degrees. 25 years of battery experience on large UPS systems here.

My Position:
Other than a couple of "Boutique" brands which are even more expensive Trojan's are the best of the Major Brands.. BUT are they worth the cost??? I think not.

Trojan suggests a 14.8 volt daily charge. Have you checked the specific gravity and equalized?

no please explain how to equalize ?

I do not have a hydrometer (yet) but will measure specific gravity when I do.

but the question was and still is
what's the difference between a T-145 and a T-145 Plus/ and is it worth the price?

Just one Source. There are lots of discussions at places like Battery University, 12 volt side of life.

If you check the SG and say one or two cells are very low they could be bad. If all of them are low but close to each other an equalize may help.

Some solar controllers have the ability to go to those voltages. Some aftermarket converters can and some use automotive chargers that may reach it. I use a Meanwell brand Wich is manually adjusted to go from about 13 to 17 volts.

Pay attention during the process and don't start it and leave it alone.

A pendulum type hydrometer is available at auto parts store for about $12. If you want laboratory grade get a Prease(?)

I have sent Trojan a message and will post their reply when I hear from them.

It seems as I asked the question to the dealer I was talking to but I simply do not recall his reply. I do recall him saying it wasn't worth the price difference.
