Review: Smart charger that works great - does run a bit warm - This ECO-WORTHY smart charger has been excellent for maintaining my batteries. The automatic charging stages work perfectly—it intelligently switches between bulk, absorption, and float modes to keep batteries in top condition without overcharging. I use it on my RV batteries and it's extended their life significantly. The interface is straightforward with clear LED indicators showing charging status at a glance. It's reliable and I trust it to maintain my batteries during storage without babysitting it. One minor note: it does get a little warm during operation, especially during the bulk charging phase. Nothing concerning or abnormal for this type of charger, but worth mentioning. I just make sure it has good ventilation and it's been fine. The build quality is solid and the cord length is adequate for most setups. For the price, you're getting a smart charger with desulfation features that would cost much more from other brands. Great value and does exactly what it's supposed to do. I'd definitely buy another one if needed. Highly recommend for anyone looking for a quality battery maintainer!

## Questions & Answers

**Q: can I only buy the wire that connects to the battery on one end?**
A: The cables are compatible with other battery tender products. Search for battery tender cables to find what you are looking for.

**Q: Will the charger wake up my battery. I have 30ah eco worthy that shows it’s at 4.7 v. Thank you**
A: Generally, the occurrence of 4.7V in the battery indicates a battery cell malfunction, and the charger is generally unable to repair it. Activation can only be considered when the battery shows 0V.

**Q: Have a eco worthy 100ah 12 lifep04 battery. at 11.7v does not seem to charge. why does amp show 0?**
A: I have used this unit to charge a 30 amp hour lifepo4 battery with no issues.  The charge time required for a 100 amp hour battery @11.7 volts would be rather long.  I do not know why the charger is reading 0 unless it is not detecting the lifepo4 battery.  At the minimum it should display 11.7 volts.  When I plug the battery in the charger detects and flashes charging amperage and voltage alternatively.  It may be a back connection between the battery and charger unit.  Hope this helps.

**Q: Does this charge lifepo4 batteries, or is it a lifepo4 battery that is used to charge various thing?**
A: The 5Amp 12V Automatic Smart Battery Charger is mainly used to charge 12v lifepo4 batteries, and can also support 12v lead-acid batteries
