Battery Tenders
#1
We are going to get an Optima Yellow Top battery for the Mach 1 but I don't want to kill it by monthly charging/over charging. What do you guys recommend for a battery tender? I have seen the external kind that you have to hook up each time you park the car and the internal kind that mount under hood and you just plug them in when you park (no need to open hood). Looking for something that monitors the battery charge level and if it drops to X volts, the tender will trickle charge back to the proper levels.

Any suggestions?

I've been using a CTEK 7002 US for about 3 years on multiple cars with lead acid and AGM batteries good results. It can be connected either way. Chuck

I recently bought (6-7 months ago) one of the Battery Tender Jr's for my Mach 1. I think it works great. I have the eyelet cables attached to the battery terminals instead of the alligator clips. About a day after I park the car I just plug it in with the connection behind/below the front bumper. Even if I forget to disconnect it and drive away, it will disconnect and not harm anything. Going to buy another one for my 85 GT.

+1 on the CTEK 7002. It is one of the few units that will not damage the yellow-top AGM battery.

I bought one from Harbor Freight that was on sale for under $10 a couple of years ago. I use it on my mother's 1992 Buick LeSabre. They bought in new in 92 and it only has 36, 000 miles on it. In fact its only been driven 73 miles since last years safety inspection. Anyway, the Cheapo Harbor Freight battery tender has worked fine. The Buick has the Max battery from Walmart.

I bought 5 of the harbor freight battery tenders when they had a coupon for 5 bucks each. I have one on each of my 4 quads and 1 on the lawnmower. Havent had a dead battery since.

I am bringing this thread back to life to see if there is any new technology in the battery tender world? I am finally going to buy a new battery and a tender this spring.

+1 on the Battery Tender Jr. I top off a battery and disconnect, charging about once per month seems to work fine.

Been using a battery tender on my mustang and jeep red optima's and they work great.

On the mustang I disconnect the negative battery cable as well. On the jeep I do not.

I am still thinking about getting a yellow top or red top Optima battery...will any tender work with Optima or will I need to stick with the Cteck 7002?
