Efest battery charger LUC V4 disassembly and fix

How to open the Efest battery chargers. I did this because I had a broken spring inside and wanted to fix it. It works great afterwards and have had no problems.

You need to have a soldering iron to fix the spring since the springs are held in via a soldered joint. You must remove the solder to put the spring back in the hole. Apply solder afterwards to secure it. A cheap solder sucker($3 on ebay) will make removing the solder much easier. I used rosin core solder to secure and reinforce the springs.

Product description

NOCO Genius smart battery chargers are some of the safest and most advanced on the market. One of our best, the G15000 15 Amp is designed to charge 12-volt and 24-volt lead-acid and lithium-ion batteries up to 400Ah. It can also effectively maintain automotive, marine, RV, lawn & garden and deep-cycle batteries. It charges 2x faster than ordinary battery chargers, can jump start dead batteries, repair damaged batteries, power DC devices and is designed to use with micro-hybrid start-stop vehicles and CANBUS electrical systems.
Guided by an onboard microcomputer, the G15000 monitors battery activity for safe and efficient charging, automatically minimizes energy consumption and provides redundant levels of safety protection, including spark-proof technology, as well as reverse polarity and overcharge protection. It can remain safely connected 24/7, while its streamlined design makes it ultra-compact, portable and incredibly lightweight.
The G15000 features external mounting holes and a rubberized base that avoids surface slipping and scratches, all while remaining impact, UV and water-resistant (IP44). Intuitive LED indicators provide visual state-of-charge feedback and diagnostic information, even when in maintenance mode. Designed for use on 120-volt, 50-60Hz electrical systems, the G15000 includes HD X-Connect battery clamps with detachable eyelet terminals and a 5-year limited warranty.
