Hybrid Battery & 12V Systems in Hillsboro, KS
The short answer
If your hybrid or EV will not start, has lost fuel economy or is showing a battery warning, one of its two batteries is usually behind it, and the small cheap one is the most common culprit.
Every hybrid and electric vehicle has a large high-voltage battery that drives the wheels, plus a small 12-volt battery that runs the computers, lights and locks and switches the car on. A long July heat wave is hard on the big one, and a January cold snap in Marion County is hard on the small one. We test both in Hillsboro and tell you which is actually at fault before you spend money on the wrong one. Bring it in, or we will come and get it.

We check the small battery first, because it trips up so many owners. When the 12-volt battery weakens, the car's computers cannot wake up the high-voltage system, so a car with a fully charged main battery can sit dead in the driveway. It is one of the most common reasons an electric or hybrid car will not start, and one of the cheapest to put right.
We give the hybrid battery the time a bigger job deserves. It wears slowly with age and heat, and the first signs are usually poorer fuel economy and the engine running more than it should. A clogged cooling fan speeds that up, and cleaning it can buy a lot of life.
We do the high-voltage work ourselves. When the pack does need repair or replacement, Moxie handles it here, including everything on the high-voltage side, with the safety procedures that work requires. Depending on the pack, we can repair individual modules, fit a reconditioned pack or replace the whole battery, and we explain what each option costs.
We know it is a big-ticket repair, so financing is available. We look after hybrid and EV owners across Marion, Harvey, McPherson, Chase and Lyon Counties, including Peabody and Marion.

What wears out hybrid and 12-volt batteries around here
- A 12-volt battery that has simply reached the end of its life, often found out on the first hard freeze
- Something draining the 12-volt battery while the car sits
- A cooling fan or filter clogged with dust and pet hair, letting the hybrid battery run hot
- Age and long Kansas summers reducing the capacity of high-voltage battery cells
- One weak module dragging down the rest of the hybrid pack
- Corroded connections at either battery
How we test hybrid and 12-volt batteries
- We test the 12-volt battery first, under load, because it is the most common cause of a car that will not power up and the cheapest to fix.
- We check the system that keeps the 12-volt battery charged, and look for anything draining it while the car is parked.
- We read the hybrid battery's health from the car's computers, including the voltage of each section of the pack and how evenly they match.
- We check the battery cooling fan, filter and ducts, since a hot battery ages fast.
- We follow high-voltage safety procedures throughout, and explain what we found and what it will cost before any work begins.
What we check
- 12-volt battery condition under load
- The charging system and any drain on the 12-volt battery
- Hybrid battery state of health and cell balance
- Battery temperature, cooling fan, filter and ducting
- Battery cables, terminals and high-voltage connections
What the repair usually is
- Replacing the 12-volt battery
- Finding and fixing a drain that keeps killing the 12-volt battery
- Cleaning or replacing a clogged hybrid battery fan or filter
- Repairing or replacing a failing hybrid battery
- Cleaning or repairing corroded battery connections

Hybrid and 12-volt battery questions we hear every week
My hybrid will not start but the hybrid battery is fine. What is wrong?
The most likely culprit is the small 12-volt battery, which powers the computers that switch the hybrid system on. If it is weak, the car stays dead even with a healthy main battery. It is a common and fairly inexpensive fix. Call or text the shop, and if the car will not move, we can pick it up within 40 road miles.
Can I jump start my EV or hybrid?
Many hybrids and EVs can be jump started through the 12-volt battery, but the procedure varies and some have a special jump point under the hood. Check the owner's manual first, because doing it wrong can damage electronics. A car that needs a jump usually has a 12-volt battery that needs testing, and we are glad to do that for you.
How much does a hybrid battery replacement cost?
The cost depends on the make and model, the size of the pack and whether a repair is possible instead of a full replacement. We test the battery first, since a cheaper fix such as cleaning the cooling fan sometimes solves the problem. You get the real price before any work starts, and financing is available.
