| -2- Contd. so that all cells will be accessible without having to go to this trouble. We fear that, if that is not the case, there will be little chance of the battery receiving proper attention and we were therefore alarmed for the life of batteries which were apparently to be subject to these drawbacks, particularly in view of the fact that the battery in this position gets much hotter from engine heat than on the running board, which heat accelerates direct evaporation and also that due to overcharging. X7736 - It has been suggested that the difficulty with regard to the removal of the lids can be met by dispensing with lids altogether. We do not agree to this, because we know from experience with batteries that have been run on experimental cars uncovered that the top of the battery does get into considerable mess with dust and damp which may have effect on the sealing compound, not to mention electrical leakage that might be produced. It has been suggested, and it appears to us to be a suitable way out of the difficulty, that we should use a metal lid{A. J. Lidsey} to the E.H. box rather than the two separate lids of the battery cases. If this can conveniently be arranged, it would seem to be an improvement. Regarding the Instruction Book instruction to attend to the battery weekly, if or when we are able to fit a charge reducing switch (automatic or otherwise, but particularly automatic) it will be possible to extend the time to double and perhaps treble what it is at present.
