Review: Great battery - I replaced my 10 years old battery on my battery booster-air compressor. Working as new again.
Review: Great for my purpose - replacements for Power Wheels batteries - I bought two of these to use in my kids' Power Wheels vehicles. The Power Wheels (a Jeep and a Mustang) were some yard sale "finds" - the vehicles were ok, but batteries were worn out. These Mighty Max batteries are a tight fit, but DO fit. No surprise, but to use them for this purpose, you need to do some minor, very basic wiring. If you are so inclined, I'd recommend you check YouTube for instructions. I chose these specific batteries for several reasons. The "nut-and-bolt" terminals allow for very secure connections to the battery. The provided dimensions told me they should fit. The sealed AGM format means they can be mounted safely in any direction. I liked that these are advertised for their long life and capacity to recover from a deep discharge. (I was concerned that my kids would run these past the point they "should" be stopped and recharged.) Also, these are 18 amp-hour batteries, almost double the 9.5 amp-hours for the Power Wheels factory batteries. That extra capacity means I probably won't see any deep discharges - in long play sessions, my kids barely made a dent in the charge (as indicated by how little time my Battery Tender charger took to recharge them.) For me, these were a great deal. Two batteries for about $70, plus a few dollars for wiring connectors and fuses; they have nearly double the capacity, and they now can be quickly connected to my Battery Tender. At the time, a factory Power Wheels battery was running about $60 (and I needed TWO). Thank you, Mighty Max! So far, so good! I expect to get a nice, long service life from these. VERY happy customer.

## Questions & Answers

**Q: What terminal does this battery have?**
A: Will this fit a DL 12V 17AH 20HR jumper battery booster?

**Q: Will the model ML-55-12 12 volt 55amp be ok for a minn kota 50 trolling motor?**
A: The owner's manual calls for a 105 amp hr battery.  It is likely that you can power it for a little while.  However, if you were going to use it a decent amount on a fishing trip, you would likely run it below a 40-50% charge level where damage to the cells start.  Repeatedly doing this will reduce the charge capacity of the battery over time.

**Q: How long is lifespan of batter? Also what’s roughly the maximum amounts of trickle charges?**
A: Lifespan depends on care and usage, but is typically 3-5 years. If battery is not being used regularly I try to charge it about once a month, and then let it set. If being used, never drain it completely, and recharge it with a regular charger instead of a trickle charger.

**Q: Does this come acid filled?**
A: yes ready to use... I use it for my trap thrower and garden sprayers and any other misc stuff around the house that need 12 volts.

### ⭐⭐⭐⭐⭐ Replaced my booster pack battery
*by S***R on 28 September 2024*

Took out the old battery and substituted this exact clone. Moderate skill level, saved my $200 booster and like new output. Won't fit all boosters, check battery specifications first. Order the right amp/Hr. Volt type
