In the cold the reactions slow down which is why if a battery is going to fail it tends to be in the winter. So let’s stop pretending our fancy new vehicles are beyond understanding, or powered by secret, reverse-engineered alien technology, or filled with milk chocolate, or whatever it is you believe is going on in there. Now this could be due to the tracker I have fitted draining it but I doubt it, I'll do some drain current tests before taking the plunge. Auto parts retailers market kits that apply directly to the battery to prolong the life of the battery. Harper-ReinstateMonica well, I would have to get official approval for a permanent change to the vehicle and my car already has the winter heater option but that only comes online after the engine is running.

You usually notice the problem (trouble with cold starts and poor charge acceptance) during cold weather. Also, the jacket is made of sturdy material so its clearly going to outlive the car so I will probably use it on any replacement car I get in the future. Cell Saver is easy to install and excess material can be trimmed to accommodate batteries of most sizes and shapes. One of the best ways to properly protect your EV battery is to find the most effective insulation and shock absorption design.I made sure to leave some gap at the top for any gasses to escape should the worst happen battery-wise.

Warming them up in the cold might keep them going a little longer but doesn't solve the problem that they are failing, that is only solved by replacement. That stuff doesn't rot when it gets wet and it doesn't burn very easily (at least, not more easily than anything else under the bonnet).They don’t have any insulation because, one, they’re designed to work to ungodly low temperatures, and two, even if they had insulation, there’s no internal heat source, so there’d be no heat for the insulation to trap in. Depends on how much stop and go driving you do and how much heat it's exposed to while under the hood. whereas cold just affects performance until recharged again (cold can also do permanent damage if that implies leaving its voltage drop too much).
