Battery Service

Are Unexpected Battery Failures Spoiling Your Drives?
Many RV and trailer owners in Sacramento struggle with battery issues. A failing battery can ruin your trip or leave you stranded when you least expect it.
Most batteries become defective for two reasons: overcharging and undercharging.
- Undercharging is a result of batteries being repeatedly drawn down and not fully recharged between cycles. This causes calcium buildup on the plates.
- Overcharging batteries results in severe water loss and plate corrosion.
Vintage Trailer Retrofits Sacramento
At McColloch’s RV Repair & Storage, we’ve helped hundreds of RV owners, trailer haulers, and fleet operators get back on the road fast.
We sell and install both 12V and 6V batteries from Interstate Batteries. We stock
a full line of deep-cycle 12V and 6V batteries and the most common motorhome starting batteries.
Whether it’s a travel trailer, utility trailer, or fully loaded RV, we know what it takes to power your journey, and we don’t cut corners.
Problem Could Be With the Charging System – We Know How to Fix
- High charging rates cause the electrolyte to boil off, thus resulting in an early death for the batteries.
- Also, if you have added batteries to your system, your stock battery charger is probably not big enough to handle the added demand.
Multi-Stage Charging
We have a solution for this problem; we stock a full line of “smart chargers”. We have multi-stage lower section replacements as well as stand-alone chargers in 55, 75, and 100 amp charge rates.
Multi-stage charging is an improved method. It optimizes charging based on the battery state of charge.
There are three stages, called Bulk, Absorption, and Float. Multi-stage charging helps in cases where the battery is fully depleted, as well as in cases where the RV is plugged into 110V for extended periods of time.
