Warranty:
All Hybrid-Battery-Repair batteries are covered by a one year/unlimited mileage warranty. They are warranteed against P1447, P1449, P1433 and related errors. During the first 90 days, we will cover shipping, or remove and install the battery at our location for free (your choice).
The following conditions apply to the warranty:
- You may not open or remove the stickers that say "Warranty void if removed".
- You must install the battery into your vehicle within 45 days of us shipping it to you.
- You must drive or idle the car for at least 30 minutes in every 45 day period. Parking the car for more than 45 days will void the warranty.
- You must not charge or discharge the battery with any external charger.
- You must provide us with any error codes that the car has.
From the above conditions, you probably now realize that it is very bad for the battery to sit without being charged. This is because NiMH batteries naturally discharge (go flat) at a rate of about 5-10% per week. If a battery is allowed to fall below certain threshholds, it may become out of balance and this will lead to a P1447 failure. In our experience, any battery that sits for more than 90 days without charging will develop P1447 errors within 18 months. This is why junkyard packs work for a while and then fail.
