Review of BatteryMINDer Model 1500: 12 Volt 1.5 Amp

Customer Ratings:

I retired from a company that uses many batteries for backup plants. These batteries are basically giant versions of a car battery except ours had a lifespan of 20-40 years. I knew that automoble batteries could be made to last much longer if the proper equipment could be found to maintain them. Until this unit was available the equipment on the market was way beyond the means of the average owner. The primary reason for the end of many batteries is sulfate build up on your battery plates.

This unit will maintain a battery and extend its life by roughly a factor of 4X. You can use it to reclaim batteries that have been lost due to sulfation.

I use a previous model to maintain batteries used for my 23KW back up generator. I bought this newer model for my father -in-law. The only difference in this and the older model is the newer unit has a slightly higher charge current and the newer unit is temperature compensated. It is common for many units on the market to boil batteries when charging in high ambient temps. Boiling is not good for a battery.

Caution*** do not try to use this unit to charge a dead battery. It was not designed for this and will not be fun watching the black smoke.

I read up on this vs the battery tender product. The car and motor cycle forums all seemed to like this one better due to the desuflation feature.

I'm using on a jet ski battery. Every year it dies and wont hold a charge and I end up replacing for ~$100. Hopefully this will solve the problem. So far, so good.

The one thing I didnt like was the accessories for the batteryminder are more expensive than the battery tender. However, the battery tender accessories (extended cords and ring adapters) plug right in to the battery minder cables. Although the product description doesn't say it, the batteryminder doesin fact use ASE connectors. So, make your own our buy the cheaper cables.

Very happy so far. I have this supporting 2 vehicles. I bought the battery tender harnesses for easy connect and disconnect. I also found a cheap 5 way connector so it is easy to run up to 4 vehicles off this unit. Does what it is supposed to.....maintains the batteries of both vehicles perfectly. I even had one of the vehicles run down (was not connected) to the point the batter would barely turn the starter and hooked it up to see if it would recharge the battery....and it did in less than 10 hours.

Honest reviews on BatteryMINDer Model 1500: 12 Volt 1.5 Amp

Had this a month now. Rescued two 48-volt packs of 12-volt

(one 12-amp and one 10-amp, roughly three years old,

used for hundreds of cycles on ebikes).

Replacement cost woulda been around $250 for all.

This little genius was $50.

Good risk-reward #s.

Batts now charging and performing like new.

(One of the 10-amps has an internal short; this

charger will not repair that!:-).

I can't comment on whether or not it increases battery life but so far it's done what I expect as far as the battery charge is concerned.
