Although ceramic takes longer to heat up, there’s a smaller risk of losing control because it does an excellent job of encapsulating and sustaining the battery heat and processing it at a consistent temperature. Using your headlights and radio to keep the camp party rocking on after sundown may seem like a great idea at the time, but you may see it differently when you’re stranded in the woods next morning.

However, battery industry should have evolved significantly, especially in latest years, so such insulation could have become obsolete. Auto parts retailers market kits that apply directly to the battery to prolong the life of the battery. Depending on the individual battery design, thermal gap pads might fit in between the individual battery cells or between the electric battery and the vehicle’s chassis. Cell Saver is very capable of damping vibration and will absorb and neutralise any damaging leaky battery acids.The insulating blankets are actually installed by Honda more for insulation from heat than cold, but clearly they benefit a battery in both ambient extremes. While many types of adhesive are used to join all the different pieces within EV batteries, the insulating materials regulate their inner temperature. I always connect the last earth connection to my vehicle away from the battery anyway, on the chassis somewhere usually. Turn off any electrical components when you turn off your car, and be mindful of how many chargers are plugged in, too. Actually it was that thread where I saw the larger battery and lots of other great info such as the OBDELEVEN coding etc.

Batteries are very susceptible to heat and vibration that can cause premature failure and hazardous acid leaks. 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. Many reviewers on another site mentioned the tape supplied did not stick well so I just used my high gloss silver aluminum tape used to seal sections of HVAC ducts or exhaust vent piping. 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.

The chemical reactions happening in the battery do produce some heat, whether it's enough to be worth considering I don't know. Then in went the battery, and I put the rest of the insulation (a long piece 12" across I believe) in around the battery. You have it backwards, battery insulators are used to protect batteries from excess engine heat rather than protect them from cold, as extreme heat is worse for batteries than cold. I too know I have arrived in life because I don’t need to do many of those similar hacks on my cars as I did years ago.

A poorly maintained engine can actually overload and damage a car battery, reducing its overall lifespan. You usually notice the problem (trouble with cold starts and poor charge acceptance) during cold weather. I agree, the only way to have a warm battery on a cold morning is to have a heater and/or tender charger on the battery. Cell Saver is easy to install and excess material can be trimmed to accommodate batteries of most sizes and shapes. When the engine is running, it’s not just generating energy for propulsion, it’s also powering all of the car’s electrical systems, including the radio, A/C, headlights, flux capacitor, etc.My old Rover 3500S (M plate 1974) (P6 / Rover 2000 bodyshape) had the battery located in the rear offside wing / chassis. nonetheless, if anyone here did similar DIY battery blanket, can you please recommended any other material? We’ll start with the battery – that noble Keeper Of The Charge that starts the whole internal combustion business going.
