Charger Maintainer Conditioner BM36271
Pros: This 'trickle' charger does the trick. After the main charger is used, I connect this unit to the batteries and leave it all night. The next day, the cart performed as expected for 18 holes of golf and when I returned home the 'main charger' would not turn ON to charge the batteries since there was too much charge left in the batteries so I just connected this unit...and that was enough!!!!
Cons: Perhaps the only 'gripe' would be that the unit does get quite warm when left for longer periods of time. Maybe a larger transformer or more efficient inverter would do the trick to help alleviate the heat.
Other Thoughts: Too bad I hadnot thought of this before. It would have saved me a lot of batteries and, of course, money as well since the previous batteries had to be replaced. Sorry I have lost the order number but Mr. JAMES VILLE supplied me with 'lots' of pertinent information. Thanks again

36 volt battery tender
Pros: This has brought my battery back from being deposited with sulfur on the plates to now the water is clear as drinking water. Great job so far; I am impressed. Product was well explained as to installation & operation in the instructions. Hopefully it will add some years to my five year batteries.
Cons: So far I have no cons to add to this review.
Other Thoughts: Is there any given number of additional years that one can expect from the Battery Minder when used on battereies?

New and hopeful user
Pros: Easy to install and set up. I am hopeful it will extend battery life and improve battery performance, as promised. Product came highly recommended by a long time user.
Cons: Extra plug to connect and disconnect every time you use the cart.
Other Thoughts: A diagram in the manual on how the various pieces of the unit's cables connect together would be helpful. I was able to look at a unit installed on another cart which was useful before I installed mine.

Battery Minder
Pros: I love the small size. The lights tell you what it is doing and you can see them from a distance and not have to walk up to it. My golf cart batteries are old and would not hold a charge very long. Since using this they have more power and pep now when you first start off and it can pull a hill much faster. If I would have had one of these from the start my batteries would be in much better shape than they are now. I liked the quick connector for the battery hook up. It's wife proof, you can only plug it in one way and you don't have to open the battery compartment to clip it on. Plus you don't have to listen to the noisy old battery charger that came with it.
Cons: I don't have any cons yet.
