TRUEcharge™3 40A 3 Bank Battery Charger - 12V

TRUEcharge3 battery chargers lead the industry with a small footprint and ultra-compact design. In addition to meeting global safety and regulatory standards, they feature low electrical interference and efficient power factor-corrected multistage charging. The TRUEcharge3 Chargers can be mounted in multiple positions thanks to their inherent drip-proof design characteristics. Unlike its predecessors, TRUEcharge3 is lithium-ion battery compatible.

Designed for recreational and commercial applications worldwide, TRUEcharge3 accepts 90–265 Vac, and 47–63 Hz, which makes traveling abroad and handling poor-quality power a breeze. The easy-to-read display of the TRUEcharge3 12 V models can be enhanced with an optional remote panel. Each model has built-in protection against surges and spikes on the AC power line.

Features:

  • Microprocessor-controlled, multistage charging algorithms
  • Settings for two and three-stage charging
  • Battery-equalization feature
  • Settings for flooded, gel, AGM, or lithium-ion batteries
  • Equipped with parallel stacking (remote panel required)
  • Ability to charge batteries drained to extremely low voltage
  • Added quiet mode

Protection Features:

  • Reverse-battery polarity protection
  • Drip-proof design
  • DC over-voltage protection
  • Over-temperature protection
  • Circuit breaker protection

Three-Stage Charging

Multistage charging ensures batteries receive optimum charging, but with minimal wear and tear, regulating the voltage and current delivered to the batteries in three automatic stages:

  • Bulk: Replaces 70–80% of the battery’s state-of-charge at the fastest possible rate
  • Absorption: Replenishes the remaining 20–30% of charge, bringing the battery to a full charge at a slow, safe rate
  • Float: Voltage is reduced and held constant to prevent damage and maintain batteries at a full charge for the remaining 20–30% of charge, bringing the battery to a full charge at a slow, safe rate

Power Factor Corrected (PFC) Charging

Less shore power is required for charging batteries, freeing up more usable AC power for running electrical devices and appliances and reducing the likelihood of tripping shore power breakers.

Good fit, good construction.
Style: CA12289
This filter was a good fit for my Corolla. It appears to be well made. The gasket is resilient and looks like it would seal well, preventing any leakage past the filter. Construction was good, with no holes or gaps in the filter paper itself. Unfortunately, the buyer usually has no way to judge the performance of an air filter, and I'm no exception, so I can't say how effective it is in actually removing dirt from the air going into the engine. But I would buy this filter again.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.
Size: AF997
This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.
